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.

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.

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.

Appium Mobile Test Automation

 

As we all know that Appium is the most preferred test automation tool for mobile applications. It is the first choice of the testers because of its flexibility i.e. it is open source, it has the best supported and highly active community of experts, Appium works across different platforms and works well with different scripting languages. Even after gaining such a popularity and having a strong community base, surprisingly,the users still make mistakes while running the mobile test automation with Appium.

 

Here are a few common mistakes that Appium users encounter while using Appium Mobile Test Automation Tool:

 

1.Unrestricted X Path Usage:

Over usage of X Path could be found in case of Selenium as well but when it comes to Appium world, it has more outrageous effects because X Path is a more dynamic way to unearth the elements. But the biggest stumbling block in this scenario is its huge performance cost due to which it becomes elusive an area. This is because Google and Apple do not provide XML or XPath related queries in a way we would need them to be. All of this hospitalizes an unmanageable cost finding elements using X Path. Undoubtedly, X Path is the most trusted method but there are several other better locator methods like ‘Accessibility IDs’ that can be used in this sitch.

 

2. Neglected usage of Accessibility IDs:

The accessibility ID locator strategy is formulated to read a unique identifier for a UI element. For both iOS and Android, getting an element by their accessibility ID is the best method. Most importantly, it is preferable because it is quicker. It should be noted that semantically accessible IDs are different than the Web IDs. However, the two shouldn’t be combined. In many cases, the accessibility IDs are used only for the purpose of testing even though they have a larger purpose. So, in order not to spoil the accessibility of the applications just for the sake of testing, the bigger purpose of the accessibility IDs should be known. If the accessible IDs are set up on the elements to make the apps testable, the app accessibility also increases, provided that the accessibility labels are sensible to the users using them. But the foremost criteria not to make automation efforts a failure is to make the application testable in the first place.

 

3. Not making a testable App:

Developing an app should be a forecasted move where in the developers, even before writing the first line of code, plan to develop an app keeping the automation in mind. This they can achieve by keeping in mind the hooks and the unique IDs for the elements in order to make the app more testable. This strategic approach would be a reason for a successful mobile app test automation. Apart from this, there should also be a concentration on the different testing scenarios in order to elude the chances of overlapping before even getting into Appium coding. An open discussion forum with the development teams to discuss the plotting of right accessibility IDs, labels or Unique IDs for the application’s elements would reduce many test automation reliability concerns.

 

4. Disregarding Application View States:

One of the challenge faced in Mobile Test Automation is not setting up the application. Most of the developers do not set up the application in order to access specific views and user states rapidly. To quote an example given by Jonathan Lipps,one of the key contributors to the Appium project.

A shopping cart functionality of the app might have ten different tests, and ninety percent of the tests might go through the same steps of logging in and searching items to be put in the cart which is a huge waste of time.

So, your team should be able to set up an app’s state and start the test in that apposite state, straightaway. This is highlighted in Appium scenario due to the fact that the mobile simulators and emulators are slow and take longer than usual to reach to the right position on the test.

 

5. Query for every element visibility:

Not querying for the visibility of every element is another way to speed up the run-time of the Appium test scripts. This leads to an additional load of calls and waiting time for Appium while in the every activity of retrieving an element. The lag can be reduced by only requesting the element attributes which are important in perspective of the test code.

 

6. Native Testing tools – Always better?

According to some developers, usage of the native testing tools is the best way to get unfailing mobile tests. For example- Espresso in case of Android and XCUITest in case of iOS. This is not good advice as neither of Google or Apple are going to release and new automation technology. When the question is of stability, the stability of code should be chosen rather than technology and in this scenario, Appium is the best choice!

As an exception, if the development team writes the tests and it’s most comfortable in mobile SDK language, using Google and Apple providers to build development environments. Also, when the constricted test-app or test code-app code integration is needed, then Appium might not be of much help. The utmost value is that Appium provides the WebDriver layer on top of the technology, which means the code can be written in any language and acts as a stable interface to that specific automation technology. Also, being a cross-platform tool, Appium allows to saves a lot of code and architecture in case of testing both iOS and Android devices.

 

7. Appium is slow:

Appium might be slower in some circumstances and also there are points in Appium codes where it does not seem efficient. Appium backs upon technologies that are slower than Appium and the curators of Appium have strategically chosen to utilize slower strategies for specific instances. For eg: Appium will certainly be slower if you are relying on XPath. The efficiency of the tool depends on how it is being used. Mostly, Appium is favored because of stability than the speed.

 

8. Not Using Appium Documentation:

The earlier Appium docs were not very user friendly. As a result, they weren’t used as much as they needed to be but the new Appium documents have been completely redesigned and reorganized. Information about the API reference to Appium, client libraries, supported drivers and Appium commands, code examples which was not provided before is all documented in the updated version. It deserves a revisit due to its newness and can be accessed at Appium.io.
