Android new testing library update

Android new testing library update

                      

          The new Android Testing Support Library provides an extensive framework for testing Android apps with espresso and Android Junit Runner with Android Studio. Now you can be able to run test cases from Android Studio with all connected devices. This library provides a set of APIs that allow you to quickly build and run test code for your apps, including JUnit 4 and functional user interface (UI) tests. You can run tests created using these APIs from the Android Studio IDE or from the command line. There are 3 major updates 1) Android Junit Runner. 2) Espresso. 3) Uiautomator 2.0

Android Junit Runner: 

         The Android Junit Runner class is a JUnit test runner that lets you run JUnit 3 or JUnit 4-style test classes on Android devices, including those using the Espresso and UI Automator testing frameworks. The test runner handles loading your test package and the app under test to a device, running your tests, and reporting test results. This class replaces the Instrumentation Test Runner class, which only supports JUnit 3 tests.

Uiautomator 2.0:

        The UI Automator testing framework provides a set of APIs to build UI tests that perform interactions on user apps and system apps. The UI Automator APIs allows you to perform operations such as opening the Settings menu or the app launcher in a test device. The UI Automator testing framework is well-suited for writing black box-style automated tests, where the test code does not rely on internal implementation details of the target app.

 Espresso:

                      

          The Espresso testing  framework provides a set of APIs to build UI tests to test user flows within an app. These APIs let you write automated UI tests that are concise and that run reliably. Espresso is well-suited for writing white box-style automated tests, where the test code utilizes implementation code details from the app under test.
