NPE when creating visible Activities in @BeforeClass #1232

activity = Robolectric.buildActivity(LoginActivity.class).create().visible().get();

gives an error when in a JUnit's @BeforeClass (see bottom for stacktrace);

while activity = Robolectric.buildActivity(LoginActivity.class).get();
(notice how create() and visible() are gone) doesn't throw an error.

I have the same issue. Did you resolve this problem?

I think I just moved it into a @Before method.

I have the issue in which ActivityController object returns null. I am using below lines to create Activity @before method
final ActivityController controller = Robolectric.buildActivity(FirstActivity.class);
firstActivity = controller.create().start().resume().visible().get();
firstActivity.getActionBar().hide();

I am getting NPE and all my tests getting failed because of this which are passed before. I am uing Robolectric 2.3

Why use @BeforeClass vs @Before? What is the status of this? Can you close this now?

@erd This is what I am talking about. This issue is really old and there is no replies on how to duplicate or if the issue still exists. Can we just close this? This should be put in @Before.

I have the same issue with yamo21 when build the test by "gradlew test".
The tests work fine when run on Android studio.
Please help.
