Migrating from Android Test Classes

About this skill

Use this skill to migrate a codebase off the deprecated android.test. testing classes that ship in the Android platform SDK onto AndroidX Test. Covers InstrumentationTestRunner → AndroidJUnitRunner; InstrumentationTestCase/AndroidTestCase → @RunWith(AndroidJUnit4) + InstrumentationRegistry/ApplicationProvider; ActivityInstrumentationTestCase2 → ActivityScenario/ActivityScenarioRule + Espresso; ServiceTestCase/ProviderTestCase2 → ServiceTestRule/ProviderTestRule; MoreAsserts → Truth/Hamcrest; ViewAsserts/TouchUtils → Espresso matchers/actions; android.test.UiThreadTest/FlakyTest/suitebuilder.annotation. → androidx.test.; android.test.mock. → real test contexts or Mockito; and JUnit3 extends TestCase → JUnit4 @Test. Use when the user sees @Deprecated on android.test., asks how to replace ActivityInstrumentationTestCase2 / InstrumentationTestCase / MoreAsserts / TouchUtils, or "old Android tests won't run on AndroidJUnitRunner".

Original description

Use this skill to migrate a codebase off the deprecated `android.test.*` testing classes that ship in the Android platform SDK onto AndroidX Test. Covers `InstrumentationTestRunner` → `AndroidJUnitRunner`; `InstrumentationTestCase`/`AndroidTestCase` → `@RunWith(AndroidJUnit4)` + `InstrumentationRegistry`/`ApplicationProvider`; `ActivityInstrumentationTestCase2` → `ActivityScenario`/`ActivityScenarioRule` + Espresso; `ServiceTestCase`/`ProviderTestCase2` → `ServiceTestRule`/`ProviderTestRule`; `MoreAsserts` → Truth/Hamcrest; `ViewAsserts`/`TouchUtils` → Espresso matchers/actions; `android.test.UiThreadTest`/`FlakyTest`/`suitebuilder.annotation.*` → `androidx.test.*`; `android.test.mock.*` → real test contexts or Mockito; and JUnit3 `extends TestCase` → JUnit4 `@Test`. Use when the user sees `@Deprecated` on `android.test.*`, asks how to replace `ActivityInstrumentationTestCase2` / `InstrumentationTestCase` / `MoreAsserts` / `TouchUtils`, or "old Android tests won't run on AndroidJUnitRunner".
