What is Expresso Framework?

Espresso is a testing framework used to write UI test cases. It automatically tests your actions with the UI of your application. The framework also ensures that your activity is started before the test run. It can be used to test across multiple applications. If used for testing outside application, you can perform only black box testing. as you cannot the classes inside the application.
 

Espresso has three components:

ViewMatchers: Allows to find the view in the current view library.
ViewActions: Allows to perform actions on the view
ViewAssertions: Allows to assert state of the view
 

Why Espresso?

It's fast: It is really important to run test cases at a fast pace as there can be many tests. UI test takes time and is costly and it is possible that you might not be able to run all the tests.
 
It's easy to setup: Setup process on local machines is easy and Android developers feel comfortable in the mobile SDK language which they use every day.
 
It's less flaky: Automated DevOps process required fast and reliable feedback. Test written in native tools is much less flaky. It gives more control over the application: It is white box testing, Espresso is inside the application, it has access to and knows how to use the code that actually runs the application for more thorough testing of each element.
 
You can use Espresso cheat sheet for quick reference as it contains most available instances of Matcher, ViewAction, and ViewAssertion.

    Espresso with pCloudy

     
    Now, run your Espresso Scripts on hundreds of Mobile devices and build quality apps faster than ever.

    Several Mobile Automation Frameworks like Robotium, Calabash, Appium , KIF & uiautomator have been developed in recent years. Among a few popular ones, Espresso is one of them.

    You probably know, Espresso is a testing framework for Android apps. It is predominantly used by developers and testers for testing user interactions (UI) to ensure that users do not encounter crashes or unexpected results while using an app.

    There are several benefits of using Espresso, the primary ones are:

    • It automatically synchronises test actions with the UI of the app being tested. Meaning? To improve the reliability of tests, it detects when the main thread is idle and runs the test commands at the appropriate time.
    • This capability also relieves you from having to add any timing workarounds, such as a sleep period in your test code.
    • Espresso has an API that is small, easy to learn and built on top of the Android instrumentation framework.
    • It also supports testing activities outside the app like camera, browser and dialer etc which Appium does not support.

    However, when you have limited time and money it is a challenge to take full advantage of your Espresso scripts in improving the quality of your apps. Luckily, there are ways to overcome this.

    Conventionally, you would spend a huge amount of money to purchase several Android devices, and spend endless hours running your scripts independently on each device. Today, thankfully you don’t have to do this anymore, there is good news. With the help of a cloud-based testing platform like pCloudy.com, you can run your scripts on hundreds on real mobile devices in parallel.
