A JUnit @Rule which launches an activity when your test starts. Stop extending gross ActivityInstrumentationBarfCase2!

README.md

Hi!

This test rule is now in the 'test-rules' support repository. Use that one!

https://developer.android.com/reference/android/support/test/rule/ActivityTestRule.html

Use:

@RunWith(AndroidJUnit4.class)
public final class DummyTest {
  @Rule public final ActivityRule<MainActivity> main = new ActivityRule<>(MainActivity.class);

  @Test public void things() {
    SystemClock.sleep(TimeUnit.SECONDS.toMillis(2));
  }
}

Use:

@RunWith(AndroidJUnit4.class)
public final class DummyTest {
  @Rule public final ActivityRule<MainActivity> main = new ActivityRule<>(MainActivity.class);

  @Test public void things() {
    SystemClock.sleep(TimeUnit.SECONDS.toMillis(2));
  }
}

This is wonderful. Have you done anything similar for Android Unit Tests? I'd love to stop extending ActivityUnitTestCase

This is definitely non-gross. Thanks Jake.

Now first-party in a test support library https://developer.android.com/reference/android/support/test/rule/ActivityTestRule.html

Does anybody know how to get Instrumentation from android/support/test/rule/ActivityTestRule ?
I'm need it for Robotium instance.

Still use Jake's @rule for now...

Hi Jake,
Is there any means by which i can get the reference of Activity before its onCreate is called?
I want this because i want to inject mocks from tests into Activity.

Android testing support library already includes their ActivityTestRule. Why do we need this ActivityRule?

androidTestCompile 'com.android.support.test🏃0.3'
// Set this dependency to use JUnit 4 rules
androidTestCompile 'com.android.support.test:rules:0.3'
