Android Studio under Gradle robolectric Unit test Configuration

1.Robolectric

Robolectric is a unit test framework based on JUnit. It does not depend on the testing capabilities provided by Android, it uses shadow objects and runs tests on a normal workstation/server JVM, unlike a simulator or device that requires dexing (Android The Dex compiler compiles the class file into the format used by the Dalvik VM on the Android device, and the process of packaging, deploying, and running greatly reduces the time of the test execution.

2. Download as Plugin

If you are under Android Studio 0.8.9, you need to follow the instructions to add additional configuration

Https://github.com/evant/android-studio-unit-test-plugin

3. Writing Gradle Configuration

Project address:https://github.com/JCAndKSolutions/android-unit-test

The following is a detailed description of the configuration
