Cannot find context in class which extends TestCase

Question

I am writing test cases for android app classes. But I am unable to find a way to get context of this class. Below is my test case class.

public class SplashScreenActivityTest extends TestCase {
    SplashScreenActivity splashScreenActivity;
    Context context;

    public void setUp() throws Exception {
        super.setUp();
        splashScreenActivity = new SplashScreenActivity();
    }

    public void testDeviceDetailsPost() throws Exception {
     //I need to access a method here which requires context
    }
}

I looked through many questions but I cannot understand their answers.

For example this question Get context of test project in Android junit test case

Answer 1

You can pass the instance variable context to the method that requires it as follows methodThatRequiresContext(context);

I'm not entirely sure what your difficulty is.

Answer 2

You can use AndroidTestCase, this class has method getContext();

Or create class without parent and add @RunWith(AndroidJUnit4.class) to class header. And use this : InstrumentationRegistry.getTargetContext();

Reminder: i must put this test class to the androidTest package, because this classes there are integration tests.

Answer 3

Good starting points to understand testing for Android.

1. Training Building effective unit tests (official documentation from Google)
2. Repository Android Testing Blueprint contains examples for different kind of tests.
