ActivityScenarioRule

class ActivityScenarioRule<A : Activity?> : ExternalResource

kotlin.Any
↳	org.junit.rules.ExternalResource
	↳	androidx.test.ext.junit.rules.ActivityScenarioRule

ActivityScenarioRule launches a given activity before the test starts and closes after the test.

You can access the androidx.test.core.app.ActivityScenario instance via getScenario. You may finish your activity manually in your test, it will not cause any problems and this rule does nothing after the test in such cases.

This rule is an upgraded version of the now deprecated .

This rule does not support calling scenario.getResult(). Use ActivityScenario.launchActivityForResult() when the Activity result is needed.

Example:

  @Rule
  public ActivityScenarioRule<MyActivity> rule =
      new ActivityScenarioRule<>(MyActivity.class);

  @Test
  public void myTest() {
    ActivityScenario<MyActivity> scenario = rule.getScenario();
    // Your test code goes here.
  }
