How can we access context of an application in Robolectric?

Question

Actually, I need to get a response of an API call, for that I required Context.

Answer 1

It is safer to use Robolectric.getShadowApplication() instead of using Robolectric.application directly.

Answer 2

Ok, so I know many others said this answer before and might already outdated

    when(mockApplication.getApplicationContext()).thenReturn(RuntimeEnvironment.application);
    when(mockApplication.getFilesDir()).thenReturn(RuntimeEnvironment.application.getFilesDir());

    sharedPref = RuntimeEnvironment.application.getSharedPreferences(KEY_MY_PREF, Context.MODE_PRIVATE);
    sut = new BundleManagerImpl(mockApplication,
            processHtmlBundle, resultListener, sharedPref);

I got null, because the when() part was AFTER the sut initialization. It might help some of you.

also I have the

@RunWith(CustomRobolectricTestRunner.class)
@Config(constants = BuildConfig.class)

at the beginning of the class

Also

 when(mockApplication.getApplicationContext()).thenReturn(RuntimeEnvironment.application.getApplicationContext()); works
