Some testing teams set up their own staging environment to test internal servers but as there is no public access which makes it difficult to perform local testing on remote devices. So how would you test your app which can be accessed through your internal network? We launched a feature called Wildnet, that enables you to test private or internal servers using pCloudy. You can test your privately hosted apps on any Android or iOS devices and implement continuous testing to ensure reduced release cycle.
Some times testers want to test their internal servers to protecting unsecured data and credentials, hide new features, and general security. But if an app hasn’t been made public, it should not delay testing across environments. When the Wildnet feature is enabled, a secure connection is created between your machine and pCloudy remote devices so you can perform testing even if the devices are connected remotely.

Let’s see how you can test local or private servers using Wildnet.

User should be registered on pCloudy platform
Executables can be downloaded from below links

    Flutter has been creating waves in the app development space since its launch. The reason is simple, it solves the problem of creating two different codebases for a single app to run on Android and iOS devices. Some experts say that Flutter which was launched by Google is to counter React Native which is used by Facebook. Nevertheless, this is a much-needed relief for enterprises as Flutter will help them save a lot of their time and resources. So let’s first understand what is Flutter.

    What is Flutter

    Flutter is an opensource mobile UI framework that can create Android and iOS apps from a single codebase. The Flutter framework includes the Flutter engine, Dart platform, the Foundation library, and design-specific widgets. Flutter apps are written in Dart programming language and runs on dart virtual machine.

    How to Create a Flutter App

    Before we start the process of app development it is important to know that there are two types of widgets, stateless and stateful. A stateless widget describes part of the UI by building a structure of other widgets that describe the UI more definitive. Stateful widgets are the widgets that can change their state multiple times and can be redrawn on to the screen any number of times while the app is in action.
    To create a Flutter app you need to install Flutter SDK and other tools required to support the framework. We will create the app in Intelli J IDE and for that, you need to install two plugins. The first one is Dart and the second plugin is Flutter. You can install the plugins by clicking on File in the menu bar of the IDE and then click on Settings.

    Then you need to create a new project and you will get a basic code layout to start with your app development. In the first line, we have the main method where we will enable the flutter driver extension and there is a run app method with MyApp class instance, to run the app.
    Flutter stateless

    In this sample code, we have used the title as the stateless widget and we have set the title as the key and for the home screen, we are using one more instance which is MyStatefulWidget(). So in this class, we have a small piece of code, where we have set values for elements like appBar, background color, and in the body, we have placed a floating action button for a counter.
    flutter statefull

    After adding the code you can run the program and you will be able to see the changed state of the counter with every click on the action button.

    Appium Flutter Driver

    Appium Flutter driver is a test automation tool for flutter apps on multiple platforms. It is a part of the Appium mobile test automation tool. But how does the Appium Flutter driver work? It uses webSocket communication to carry WDIO script to instantiate the flutter driver and the request will be sent to the particular application. Then the AUT will send the response to the script through the Appium Flutter driver.

    Appium Flutter driver
    Appium Flutter driver

    You can also build Appium in your machine through the source code. Once you have cloned the source code, run npm install then npm run built and type a command node to start the Appium server. You can download the package from GitHub. The package contains Appium Flutter Driver and Appium Flutter Finder. You can clone the sample project to get the WDIO code.
    Flutter sample

    In the terminal, you can see that to automate flutter application we have used Flutter as an automation name for both Android and iOS apps. You can see that port is 4723 and in the capabilities, we have mentioned osSpecificOps, automation name: ‘Flutter’. We have mentioned the app path at the top with the device name and platform name and we created an object.
    Flutter Terminal

    Appium==OS environment is ‘android’ which will pick all the information and specify in the capabilities and it will pass a post request to the server.
    Now here we are trying to find the element using CounterTestFinder and a ButtonFinder to click on the button. In the next line, we have created a driver using a remote method.
    Then we have switched the Native App context to Flutter. You can switch this if you are using the Flutter app. Once the app is launched, we are validating that the counter text finder has value as zero by calling Flutter APIs internally. So here we are using two actions, one is clicking and the other is touch.
    Flutter code

    The button is to be clicked two times and thus we have used strictEqual function. In the last line of code, we are deleting the session.
    Now to run the test we need to pass the environment variable to connect the device.
    Flutter demo

    Then we will check if our Appium server is running.
    Flutter Appium

    Then once you run the code you will be able to see the actions performed on the device and the counter will change to two.
    Flutter Appium automation

    This is how you can automate your Android and iOS app testing using Appium Flutter driver. Although there are many benefits of using Flutter, there are some limitations as well. The first thing is that you need to learn Dart language to develop and automate the Flutter app.
    Suppose you need to run automated tests on multiple devices, then you will have to fire multiple commands in the terminal. Appium flutter driver depends on Flutter Driver APIs and as it’s still not matured enough, some actions cannot be performed.

    Espresso is a testing framework for Android which automatically synchronizes your test actions with the UI of your app. It also lets the test wait until all the background activities have finished.
    The pCloudy utility uploads your Application APK, test APK and other APK files to pCloudy. It will then acquire a device to run your test on, execute those tests and report back the status and test report.
    In pCloudy you don’t have to set up the environment. Just follow these simple steps.
    After the test cases are run you can see the detailed reports. Once automation ends, the device under test will be released automatically so that you or other users can use it later.
    There are two ways you can execute espresso test cases. Here are the steps for both
    1. pCloudy UI Dashboard
    a. In pCloudy UI there is a section called Automation where you will find multiple automation frameworks integrated to the platform.
    b.Select the Espresso automation and to fill in the required details.

    ii. AndroidXJUnitRunner (androidx.test.runner.AndroidJUnitRunner)
    d. Select your Application and Test Application.
    e. Select the required devices.
    f. Click on Next button and Schedule the automation by clicking on the Schedule button.
    g. You will get a dialog box. Click on Ok.
    h. You will get the active session details on the Dashboard and you will also be able to see the Live view.
    i. Liveview will help you to see the live execution on your test cases. Click on the Liveview icon
    2.pCloudy Utility
    a. Download the espresso starter pack from here and Unzip it
    b. You will find two files,
    i. pCloudy_Espresso.jar
    c. Place the config.properties file and pCloudy_Espresso.js file into the same directory.
    d. Update the config.properties file as guided in the comments in the file.
    e. In your workspace, run the command by typing the java -jar pCloudy_Espresso.jar
    f. This will upload the required files which you have mentioned inside the config.properties files.

    g. You will get the status of the Automation in pCloudy Dashboard ActiveSession.
    h. Even on the pCloudy dashboard, you can use the Liveview by which you can see the running test cases.
    i. Once the test execution is over, You will get a URL of the test execution report on the terminal.
    j. You can open the report from the dashboard Report section also. In the report, all the test details will be there as shown in the screenshots below.
    k. You will also get individual device reports. Inside the test case level details, you will find performance details, test case logs, device logs, and video files.

    Studies have indicated that after installing a new app, only a quarter of the users return to the app on the second day. The retention rate is eminently low and the majority of the users uninstall the app after the first use. You might have guessed the reason for this. If you think the reason is scanty testing then you are correct. A lot of times testers show little interest when testing is repetitive. Although regression testing is crucial to the success of the project, it is often overlooked to some extent. So let’s understand the concept of regression testing.

    What is Regression Testing

    In simple terms, regression testing can be defined as retesting a computer program after some changes are made to it to ensure that the changes do not adversely affect the existing code. Regression testing increases the chance of detecting bugs caused by changes to the application. It can help catch defects early and thus reduce the cost to resolve them.
    Regression testing ensures the proper functioning of the software so that the best version of the product is released to the market. Although, creating and maintaining a near-infinite set of regression tests is not feasible at all. This is why enterprises are focusing on automating most of the regression tests to save time and effort.

    Types of Regression Testing

    There are different types of regression testing for different phases of testing. Let’s understand the types of regression testing.
    Unit Testing: It is done when coding changes are made for a single unit and a tester re-runs all previously-passed unit tests. Often automated unit tests are built into the code to make unit testing efficient.
    Progressive Testing: This type of testing works effectively when there are changes done in the software/application specifications as well as new test cases are designed.
    Selective Testing: In this to cut down the retesting cost and effort, testers use a subset of the current test cases. A test unit must be rerun when there are changes in the program entities it covers.
    Retest-All Testing: In this, we reuse all test cases even where the changes have not been made. It shouldn’t be done where there is a small change in the application as it is very time-consuming.
    Complete Testing: Complete testing is effective when multiple changes have been done in the existing code. It is done to identify unexpected bugs and the final system can be made available to the user once complete testing is done.

    How to Derive a Regression Testing Plan

    Whenever there is a change in the app or a new version is released the developer carries out these tests as a part of the regression testing process.
    First, the developer executes unit-level regression tests to validate the code that they have modified along with any new test that is created to cover any new functionality. Then the changed code is merged and integrated to create a new build of AUT. After that smoke tests are performed to assure that the build that we have created in the previous step is good before any additional testing is performed.

    These tests can be executed automatically by continuous integration services such as Jenkins. Once we get the assurance that the build is perfect then we do the sanity testing to confirm that the functionality works as expected and known defects are resolved before conducting integration testing.
    Integration testing is performed to verify that the units of the apps interact with each other and with backend services such as databases. The next step is to schedule regression tests depending on the size and the scope of the code either a partial or a full regression test may take place.
    Defects are reported back to the development team and many require additional runs of regression testing to confirm the resolution. So based on the test reports you can analyze and figure out what test cases can be added for the next checking process as well and you create your report on that.

    Regression Testing Challenges

    Automation is always a smart move but there will be some challenges that would need your attention. Let’s have a look at the challenges that you might face in automation testing.
    Cost is High
    In terms of business expenses, the company will have to invest a lot of time and money in repetitive testing. Also, there’s no specific return on investment that is attached to regression testing. It is a complicated process and to explain the importance of regression testing in terms of business benefits to the management is really difficult. But this has to be done to draw the budget for the testing even though it is expensive from a management point of view.
    Unstructured Information
    If new testers are recruited during the ongoing software testing project, either to speed up the process or to release some of the tasks. The existing testers in the organization might not have time to give complete details about the functionalities and features of the app, existing bugs, delivery time, etc. The new testers might have to initiate testing with inadequate data about the ongoing testing project. Challenges like these need an appropriate test strategy for efficient collaboration.
    Time Restrictions
    The focus of enterprises is on developing quality apps and delivering them faster. This is why regression testing is always time-bound. Testers always get a deadline to complete the process of regression testing. To keep pace with time, The testers might have to take chances to give more importance to the critical regression tests and skip a few tests. It is a serious challenge as it is critical to decide which tests can be skipped.
    Maintenance and Optimization
    A major challenge is to maintain and optimize the existing regression test suites. The existing regression test suites might need modification like adding, removing or editing the existing test cases, whenever there are new changes. All this need to be done before the deadline fixed for the regression testing. Therefore, optimization and maintenance is another challenge that needs attention.

    Best Practices to Perform Regression Testing

    Now that we are aware of the challenges in regression testing. Let’s have a look at the key changes we can do to enhance it.
    Focus on the Frequently Used Paths
    Frequently used paths also make the most frequent use cases for your app. They must include the most popular features and the basic functionality of your app. You should be aware of the core group of users and their usual interaction with the app features. The regression test cases must ensure that this core functionality is working as expected.
    Update the Regression Pack Regularly
    A regression pack is a collection of test cases that are performed when a new app version is released or if there are any new updates. The tests in a regression pack are created keeping in mind the app’s older version requirement specifications. Ad-hoc tests should be included in the regression pack to keep it up to date. You wouldn’t want to waste your time on tests to validate an old feature that is not included in the latest version of the app.
    Create an Entry/Exit Criteria
    The entry/exit criteria that we usually follow in the software development lifecycle can be implemented in regression testing as well.
    As entry criteria, a fixed set of conditions need to be met like reviewing bugs and performing regression testing to fix those bugs. Exit criteria can be applied with a fixed set of conditions like making sure that all the tests are executed and no bugs remain unfixed.
    Automate Regression Tests
    Automating regression tests makes the process much more efficient and saves time and effort. Repetitive testing can make testers lethargic and testers might lose motivation. It also affects the quality of their work as the testing is repetitive. Automated regression testing will free up resources to work on the more complicated tests. When we use automation, the test cases along with the software can also be reused which increases the return on investment.

    In a Nutshell

    Change is hardest at the beginning, messiest in the middle and best at the end. This quote by Robin Sharma suits the importance of regression testing in delivering a smooth functioning app. As mentioned earlier in this blog, different types of regression testing can be performed at all stages of the testing life cycle. And there are ways to overcome the challenges in regression testing too.
    One option is to use a cloud-based app testing platform which will enhance the effectiveness of regression testing by many folds. There will be hundreds of devices to perform testing in parallel and features which complement regression testing automation.

    In the last blog in this series we learned how to start the Appium server and launch app from the code. In this blog we will understand how to setup Appium on a Mac machine.


    • Mac Book
    • Xcode
    • Simulator or real device
    • Appium
    • Eclipse
    • Java

    The first step is to install Xcode in the Mac Book. To do that, open app store and search for Xcode and click on the Get button to download Xcode.

    download Xcode
    Then click on the Install App option. This will install Xcode on your Mac machine. Now click on the Agree button if you agree with the terms and conditions and it will start installing components.

    Once the Xcode is installed, you need to select “Create a new Xcode project” and you will be redirected to the template selection option.

    template selection
    You may select any of the templates or leave default settings as they are. Click on the next button to navigate to the next screen.

    Now you will be asked to provide a product name and other product-related settings.

    Enter the required details and click on the next button. In the last seen of product settings, you will be asked to give the location in which to save your project.
    Select the location anywhere as per your requirements and click on the create button.

    create button
    Once the project is loaded go to the Product menu option and click on the Run option.

    Run option
    Once you click on the run option, it will launch iOS simulator.

    iOS simulator
    Now right click on the simulator icon on the doc panel and select the keep in doc panel. In this way, you don’t need to start Xcode to launch the simulator. Thus you don’t need to open the Xcode project each time to launch iPhone simulator. If you want to see the list of simulators, got to the Window menu and select the Devices option. You will get a list of all the simulators available with this version of Xcode.

    Installing JDK and setting the path

    Download JDK for Mac OS and once the file is downloaded, double click on the file and install Java.

    install Java
    Now you need to set the Java installation path in your environment variable. Open a terminal and write “open.bash_profile”.

    Open a terminal
    If “.bash_profile” does not exist then execute the command “touch~/.bash_profile”. This will create the file. So when you execute the command, it opens the “.bash_profile” file.

    execute the command
    Copy the path to JDK home, write export JAVA_Home= and then save this file. Open command prompt and execute the java – version command. Open Appium.io and click on Download Appium button.

    Appium button
    Now download the latest .dmg file and once downloaded, double click on the .dmg file.

    dmg file
    It will open a new window where you need to drag and drop Appium into the application folder.

    application folder
    Search for Appium and double click on the Appium icon. This will launch the Appium server on your Mac machine.

    Appium icon
    To Launch Appium on a simulator click on the Start Server button.

    Now click on the Start Inspector Session button in the Appium server.

    Start Inspector Session
    Once you select pCloudy as the cloud provider from the list you can click on Done.

    cloud provider
    Then you need to enter the Hostname, User name, API Key, Desired Capabilities and then click on Start Session.

    Start Session
    Your simulator is now connected.

    Now you know how to setup Appium on Mac and in the previous blogs in this series we explained how to write the test script and start Appium server. In the next blog we will learn how to use Appium inspector to identify elements in an app.

    There are more than 5.5 Million apps available on Google Play and Apple App Store combined and by 2022, the number of app downloads will be around 250 Billion. The number of smartphone users in the world is more than 3 Billion and the users prefer using smartphones instead of desktop. This data shows that the mobile app market is very competitive and growing. In this age of digital transformation, the focus of enterprise mobility is to provide better user experience at great speed. The launch of 5G will further complicate the app development and testing process initially. But apart from this, there are three main challenges to overcome and pCloudy is leading the path to bring positive change. Let’s look at these challenges and their solutions.

    Challenges Faced by Enterprise Mobility

    There is a growing demand for quality at speed in the mobile app industry. The current market dynamics are such that it is necessary to provide the best quality product in less time to remain in the competition. When we talk about mobile app testing, quality can be maintained only when the enterprise can achieve scale. There is a myriad of devices in the market with different OS versions, browsers, Custom ROM, etc. and the app should be compatible with all the devices. How can ensure this and most importantly, how can we speed up the testing process on multiple devices? pCloudy can help you overcome this challenge with its best in the class features. Let’s have a look at them one by one.

    Parallel Testing to Achieve Scalability

    If we are talking about scalability then testing your app on 5,10 or even 20 devices are not enough for the enterprises to ensure a bug-free app. pCloudy enables to testers to run your test scripts concurrently on 50, 100 or maybe more devices. Enterprises have the option to perform parallel testing in our public cloud or in our plug & play on-premise infrastructure solution. With more than five thousand device browser combinations, enterprises can ensure that the application is working properly in all the devices.
    Parallel Testing

    Parallel testing on 50 devices

    You can see in the picture above, we have set up a device infrastructure for 50 devices for demonstration. Similar device setup can be provided for our on-premise solution and public cloud users can just log into the pCloudy platform and book the devices to perform testing. These real devices can be accessed remotely on the cloud which makes it more convenient for the users as there are no location constraints.

    Progressive Reports to Improve Quality

    It won’t be efficient to go through each and every report to analyze the data for every device. Instead of that, you get intelligent results where you can do a quick analysis of the errors and then debug quickly. In the pic below you can see the list of results for different builds with their start time, progress, status, and Action.
    In the status, you will be able to see how many tests pass, fail, and errors. This way you can concentrate on the tests which failed and you will save time as you don’t have to manually go through all the cases.
    Progressive Reports
    You can integrate any reporting framework with your existing Appium setup. The same way you have to configure with pCloudy by adding a one-line code while creating an asset.
    Test Case Report
    In the pic above you can see the test case result in detail. You can see the tags, test case name, build, Automation, and the live status of errors.
    Progressive report
    Once you expand the test case you can see the logs, Jason format, screenshots, video for that particular session. This information can be used to expedite the test execution.

    Integration with AI to Speed up Mobile App Testing

    The next challenge is to speed up and simplify the test script creation process. Usually, the procedure is to connect the device to the system and use an automation framework like Appium to use object repositories. If you are using images then the XPath may change depending on the devices.
    This AI based utility will help you to get the object repository for the entire page. So if there is an icon for contacts then this utility will automatically recognize the element.
    AI Code
    In the code, you just need to declare the driver for Appium and for pCloudy as well. Then you need to initialize the drivers and start using the code generated using the AI utility. This is how the script creation is expedited using AI.


    To sum up, pCloudy has come forward with solutions for the enterprise mobility to deliver quality at speed with scale. Whether it’s parallel testing, progressive reports or creating a script using AI-based utility, all these features fix the problems that were mentioned earlier. The proverb “change is the only constant” fits well as pCloudy comes up with updates on a regular basis to resolve the issues and make mobile app testing better.

    It is necessary to check cross-browser compatibility to ensure that the app is working fine on all the web browsers. Sometimes when you open an app on a web browser it might not look or feel convenient and there might be some issues like image/test overlapping, navigation, alignment, etc. These issues degrade the user experience which will eventually lead to low traffic and existing user attrition. This is why cross-browser testing is an integral part of the QA process and should not be avoided.

    What is Cross Browser Testing?


    • Browser compatibility testing can be automated or done manually.
    • In manual cross-browser testing, the testers have to test the app on multiple OS, device and browser combinations. This is why it is a time-consuming process.
    • The main issues are with the UI and the main features are tested on different screen sizes to check if the look and feel are similar to what was expected.
    • In automated cross-browser testing, there is a need to create the test script initially then there is minimal human supervision is required.
    • Efficient automation tools will take much less time to perform the testing.


    Automation for Cross Browser Testing

    Automation has reduced the time and effort put into cross-browser testing by 80 percent. The only human work goes into writing the initial test script and selecting the tool. Let’s look at the reasons why we should automate cross-browser testing.

    Run Multiple tests simultaneously: When it comes to regression testing and running multiple tests for an app, automated testing saves the day. So if your app is already in the market and you launch a new version then automated cross-browser testing helps you to deliver faster. When a new feature is to be launched in the app and the build is sent to the testing team, they will take some weeks to perform all types of testing. This time can be reduced to a few hours using Automation testing tools.

    Improved test accuracy: Even the experienced testers can make an error while testing the app manually. Although in Automation testing the accuracy is very high and the detailed reports are recorded. Testers can review the testing process and create new Automated test with the help of those reports.

    Save Time and Money: Cross-browser testing require repetitive tests and so it can be a boring and time-consuming process. These repetitive tests can be automated to save time, effort and return on investment. You just need to make sure that everything is included in the test script to avoid gray areas in the app functioning.

    Better Test Coverage: The time taken to perform any web app testing is dependent on the type of feature or functionality you have to test. The length of the test affects the cross-browser testing process. For example, end to end testing can be difficult if done manually. It will take much time and effort to do so. This why automation testing can be used if you have to run the test on multiple devices with multiple browser-OS combinations.

    Feasibility of Local Test Environment

    There are many types of devices in the market with different screen sizes, OS versions, Browsers, etc. To create the desired test environment, you will have to have all these combinations and you will have to set up a device lab. This will take huge investments and efforts to maintain the lab. Also, there is an issue of geographically distributed teams accessing the devices. Apart from that, you will have minimum flexibility as scaling up or down will be difficult.

    Advantages of Cloud-Based Cross Browser Testing

    There are many Cloud-based cross-browser testing tools in the market which will help you achieve your testing goal without investing a lot. This is one of the reasons why cloud-based cross-browser testing is better than setting up a local test environment. Let’s have a look at some other advantages which will give you a reason to opt for cloud-based option.

    Multiple Test Environment Support: Heterogeneity in the operating system versions, device screen sizes, browser versions makes it necessary to perform tests on many combinations of device/OS/browser. This means a lot of effort will be put in to test the functions of an app on multiple devices. This could be avoided by testing the app on a cloud-based device platform.

    In the cloud-based testing platform, you will be able to select the devices of your choice and perform parallel testing on multiple devices without buying one. This will save you money and effort to put up a device lab. While running the test in parallel on multiple devices with different OS browser combination will save time, it will also increase the accuracy significantly as compared to testing the app feature manually.

    All time access to resources: The testing team can access the tool at any time by just logging into the tool and selecting the devices according to the market research report on popular devices in the region. Testing can be performed at any time which means there is no foundation and this comes in handy when the deadline is near. Having all time access to the device cloud will contribute to continuous testing and ensure faster deployment.

    Scalability: While handling multiple projects the team might have needed many devices at times and very few on some occasions. This means that most of the devices in your device lab might rarely be used and sometimes you might have to buy more to add in the environment. This improper management of resources can be avoided by using Cloud-based device platform. Here you can select the devices which you actually need to perform the cross-browser testing and as all the devices are virtual, there is no worry of managing the extra devices.

    Collaboration: There are tools to communicate and collaborate with the team which impacts on your productivity in a good way. Test reports can be generated which are elaborate and provides all the information about the health of the app. These reports can be shared with the team online to analyze and resolve the issue.

    Initial time and cost: To set up an actual device lab you will require dedicated cloud/network expertise and suitable infrastructure. On the contrary, if you use cloud-based platform for cross-browser testing then you don’t have to worry about the infrastructure and initial setup cost. Also, you will save a lot on maintenance cost and everything is preconfigured.

    Comprehensive testing: To perform thorough cross-browser testing, you need a permutation and combination of mobile devices with different screen size, OS, browser, other features relevant to the app function. This will make a big hole in your pocket if you wish to buy that many devices. This is why cloud-based testing platforms are the best option.

    Cross Browser Testing

    Types of Cross Browser Functional Testing

    There are three types of cross-browser functional testing, multi-browser testing, multi-version testing, and concurrent testing. Let’s get familiar with all three of them.

    Multi-Browser Testing: The application under test is opened on different browsers like Chrome, Safari, Opera, UC Browser, etc to check if the app works consistently across all the browsers. The app feature can be tested on multiple devices of different configurations and browser combinations.

    Multi-Version Testing: In this type of testing the AUT is tested with different versions of any browser to check if the functioning is smooth. So if your app supports chrome version 40.0.2214, then the app must be tested on all the versions of chrome after 40 to check the functionality. One tester can perform the task and multiple devices will be used to perform the testing.

    Concurrent Testing: In this, the application under test is checked simultaneously on different web browsers. There are four variations of this testing – single browser distributed concurrent testing, multi-browser distributed concurrent testing, Multi-browser concurrent testing, and single browser and single browser concurrent testing.


    Cross browser testing combined with cross-platform testing will ensure that the app works smoothly in any type of environment. Especially for web apps, cross-browser testing cannot be avoided. Studies have suggested that people uninstall the app after using it once if the UI is not user-friendly. Even the app ratings on App Store and Play Store are affected by the user experience, leading to a lower number of downloads. Enterprises can save a lot of money and build a good report among the users by proactively testing their app thoroughly.

    We all know that testing your application is important as it ensures security, customer satisfaction, and saves money in the long run. Sometimes it can saves lives as well. Here is an example to make my point; China Airlines plane crashed due to a software bug on April 26, 1994, which took 264 lives. In software testing, Unit testing is the first level where most of the issues can be rectified and this saves time. Let’s understand what is Unit testing.
    Level of testing

    What is Unit testing?

    In Unit Testing, individual components of a software application are tested during the development phase. Unit Testing is usually done by developers instead of testers. A function which is in the form of a section of code is tested to verify the accuracy. Drivers, unit testing frameworks, mock objects, and stubs are used to perform unit testing.

    How to Perform Unit Testing

    Unit testing is usually Automated, but sometimes it can be done manually. A manual approach can be done with the help of an instructional document. Unit testing can be performed on all types of mobile applications.
    In automated unit testing, a developer writes code in the app to test the function or procedure. Once the app is deployed, that code can be removed. The function can be isolated to test the app rigorously and it reveals the dependencies between the code being tested and other units. Then the dependencies can be eliminated. Most of the developers use unit test automated framework to log the failing test cases.
    Unit Test Life Cycle

    How to Improve Unit Testing

    There are some points to keep in mind while performing unit testing. Use consistent naming conventions and test one code at a time. Make sure that there is a corresponding unit test case for a module if there is any change in the code. All the bugs must be fixed before moving to the next phase. It’s better to test as you commit a code to avoid errors. Focus more on the tests that affect the behavior of the system. Online Android emulators can be used to perform unit testing in some cases.

    Advantages and Disadvantages of Unit Testing


  • With Unit Testing, the speed of development will be faster. If you perform developer test instead of unit test then you need to set breakpoints, fire up the GUI and provide inputs. But if you do unit test then, you write the code, write the test and then run the test. You don’t need to provide the inputs or fire up the GUI. In the end, you have a more reliable code. It takes less time to find and fix the bugs during unit testing than in system or Acceptance testing.

  • Reusable codes reduce the effort and save time as the code needs to be modular in unit testing.

  • More reliable code as the bugs are fixed in the initial stage.

  • Easy to debug as only the latest changes need to be debugged if the test fails. Whereas if you test on a higher level, then you will have to scan the changes made within weeks or months.

  • We can test a part of the project without waiting for others to be completed due to the modular nature of the unit test.
    The only disadvantage with Unit Testing is that it’s not possible to check all the execution paths and it cannot catch broad system errors or integration errors.


    It is evident that unit testing cannot and should not be avoided. Rather the developers should opt for Test-driven development where they can write the test and then write the code on the basis of that test. You just need to get the suitable tools which will further reduce your testing efforts.

    [xyz-ihs snippet=”quickLinks-mobile-app-testing”]
    In the year 2020, there will be around 5.5 Billion mobile users which accounts for 70% of the world population. More mobile users mean more apps and more competition and to lead the competition we need to make sure that our app is flawless. If nearly half of the bugs in your mobile app are discovered by the users, your app’s ratings are going to decline and so are the downloads. This is why the right choice of mobile app testing techniques must be followed in the decision making process.

    Mobile App Testing Strategies

    Today, the mobile app market is highly competitive. To be better every day and survive for long, the QA team has to follow a mix of plans that would be responsible for taking the right testing decisions. The testers have to formulate testing strategies to face every situation fearlessly and immaculately. Mobile apps have to be perfect before reaching to the end users so there have to be certain decisions to be taken regarding the testing plan. The following model of mobile app testing plans can be considered for better execution.
    In the planning Stage, decisions like Selection of Device matrix, Test Infrastructure (In-house vs. Cloud, Simulator vs. Real device), Testing scope, Testing Tools, Automation (Framework/Tool) are taken. Since it is the first stage, it is the most important one as all the further stages would depend on these decisions. In the next stage which is execution and review, decisions regarding Test Case Design, Testing of user stories, testing types as per Sprint Objective, Progressive Automation, Regression Testing, Review and course correction are taken.
    We are going to discuss the planning stage aspects more elaborately

    Device Matrix:

    It is an important factor, choosing the device as per your target audience’s behavior matters in decisions regarding resting. There are different approaches to the selection of the device matrix.

    Approach 1- Selection of Devices based on market research.

    Determine the set of devices with your target operating System that will have the highest occurrence of accessing your application by using app purchase data and analytics. For Example- if you support both Android and iOS, and your application will be used across millions of Samsung, Google Nexus and Moto G devices but only thousands of iPhones, you prioritize testing on the Google Nexus and Moto G above the iPhone device. So, this test plan will consist of testing on devices which are prioritized by your market analysis.

    Approach 2: Categorize the devices based on Key mobile aspects

    This approach highlights the categorization of the devices based on certain mobile aspects which can be considered in formulating the testing strategy. The categorization goes as:
    Mobile device categorisation

    Test infrastructure

    This is another element of the planning stage. This focuses on Strategizing on the Infrastructure components like hardware, software, and network which are an integral part of test infrastructure. It ensures that the applications are managed in a controlled way.

    Real device, Emulators or Mobile cloud-Where to test?

    Choosing the right platform to test as per the testing needs is very important i.e whether to test on the Real device or an emulator or on the cloud

    Real Devices

    Testing on a real device is anytime more reliable than testing on a simulator. The results are accurate as real-time testing takes place on the device in a live environment. It carries its own disadvantages as it is a costly affair and not all the organizations are able to afford a complete real device laboratory of their own.
    Reliable- Testing on Real devices always gives you an accurate result
    Live Environment- Testing on real devices enables you to test your application on the actual environment on which your target audience working on. You can test your application with different network technologies like HSPDA, UMTS, LTE, Wi-Fi, etc.
    User experience- Testing on Real devices is the only way to test your Real-time User experience. It cannot be tested through Emulators or devices Available on Cloud.
    Maintaining the matrix- You cannot maintain such a huge matrix of mobile devices in your own test lab.
    Maintenance- Maintaining these physical devices is a big challenge for organizations.
    Network providers- There are more than 400 network providers all over the world. Covering all these network providers in their own test lab is impossible.
    Locations- You cannot test how your application behaves when it is used in different locations.


    The emulator is another option to test mobile apps. These are free, open source and can be easily connected with the IDE for testing. The emulator simulates the real device environment and certain types of testing can be run on it easily. However, we cannot say that the results of emulators are as good as those of real devices. It is slower and cannot test issues like network connection, overheating, battery behavior, etc.


    Price- Mobile emulators are completely free and are provided as part of the SDK on every new OS release.

    Fast- As Emulators are available on the local machine so they run faster and with less latency than Real devices connected to a local network or devices available on the cloud.


    The wrong impression- Even if you have executed all test cases on emulators, you cannot be 100 % sure it will actually work in the real environment.

    Testing Gestures- Gestures like Pinching, Swipe or drag, long press using the mouse on simulators are different in using these gestures on real devices. We cannot test these functionalities on emulators.
    Can’t test Network interoperability- With the help of Simulators you cannot test your application with different network technologies. Like HSPDA, UMTS, LTE, Wi-Fi, etc.

    Testing on Mobile Cloud

    Mobile cloud testing can overcome the cost challenges like purchasing and maintaining mobile devices. It has all different sets of device types are available in the cloud to test, deploy and manage mobile applications. The tests run virtually with the benefit of choosing the right type device-OS combinations. Privacy, security, and dependency on the internet can be a challenge in this case but it has many benefits that can cater to different testing scenarios.
    Mobile cloud

    The organization can choose the right mix of above-mentioned platforms as every platform carries its own advantages and disadvantages. Sometimes a combination of real and emulators is preferred and sometimes all three can be considered as per the testing strategy.

    Devices Availability- Availability of Devices and network providers is a big gain for cloud users.
    Maintenance- When you are using cloud services. Forget about maintenance. These providers take responsibility for maintaining these devices.
    Pay per use- You don’t need to buy a device. You only have to pay for the duration you use that device.

    Parallel Execution- You can test your complete test suite on multiple devices.

    Cost- Some providers are a bit costly
