ActivityTestRule<T extends Activity> This class is deprecated. use ERROR(/androidx.test.core.app.ActivityScenario) or ERROR(/androidx.test.ext.junit.rules.ActivityScenarioRule) instead. They offer a simpler, and safer way of controlling Activity lifecycles.

Here are some tips to consider when converting to ActivityScenario/Rule:

  1. For simple cases where you want to launch the Activity before each test and tear it down after each test (eg you are using ActivityTestRule(Class)), convert directly to ActivityScenarioRule.
  2. If you need control over when to launch the Activity (eg you are using ERROR(/#ActivityTestRule(Class, false, false)), use ActivityScenario.launch. Its recommended to wrap the launch in a try-block, so the Activity is closed automatically. try (ActivityScenario.launch(activityClass)) { ... }
  3. If you need access to the Activity during the test (eg you are calling getActivity() provide a Runnable callback to ERROR(/androidx.test.core.app.ActivityScenario#onActivity(Runnable)) instead. The callback provided to onActivity will run on the application's main thread, thus ensuring a safer mechanism to access the Activity.
 
AtraceLogger Class contains helper methods to dump atrace info asynchronously while running the test case.

DisableOnAndroidDebug The DisableOnAndroidDebug Rule allows you to label certain rules to be disabled when debugging. 

G

GrantPermissionRule The GrantPermissionRule Rule allows granting of runtime permissions on Android M (API 23) and above. 

P

ProviderTestRule A TestRule to test ContentProviders, with additional APIs to enable easy initialization such as restoring database from a file, running database commands passed in as a String or a file. 
ProviderTestRule.Builder A Builder to ease ProviderTestRule creation. 

S

ServiceTestRule A JUnit rule that provides a simplified mechanism to start and shutdown your service before and after the duration of your test. 

U

UiThreadTest Classes and methods annotated with this annotation will be executed on the application's UI thread (or main thread). 
UiThreadTestRule This class is deprecated. use UiThreadTest directly without this rule. UiThreadTest is now supported as part of the core Android test runner to provide the ability to run methods annotated with @Before and @After on the UI thread regardless of what @Test is annotated with.
