Use this skill to structure a Jetpack Compose UI test class the way androidx itself writes them — @MediumTest + @RunWith(AndroidJUnit4::class), a single createComposeRule(StandardTestDispatcher()) rule, hoisted mutableStateOf declared above setContent { }, and the Test → Find → Assert → Act → Re-assert flow. Covers when to use createAndroidComposeRule () for custom Activities, how to drive state from outside the composition via runOnIdle { }, why state must NOT be hoisted inside setContent, and why @get:Rule createComposeRule() and runComposeUiTest { } MUST NOT both appear in the same test. Use when the developer asks "how do I write a Compose test", "where do I declare state", "how do I name the test class", "MediumTest vs LargeTest", "rule.setContent inside @Before", or shows a test class that won't compile or doesn't drive state from outside.

Send it to your agent. Paste it into your coding agent’s chat and send.
Review the setup. Your agent checks the skill’s instructions, requirements, and installation scope.
Use this skill to structure a Jetpack Compose UI test class the way androidx itself writes them — `@MediumTest` + `@RunWith(AndroidJUnit4::class)`, a single `createComposeRule(StandardTestDispatcher())` rule, hoisted `mutableStateOf` declared above `setContent { }`, and the Test → Find → Assert → Act → Re-assert flow. Covers when to use `createAndroidComposeRule<MyActivity>()` for custom Activities, how to drive state from outside the composition via `runOnIdle { }`, why state must NOT be hoisted inside `setContent`, and why `@get:Rule createComposeRule()` and `runComposeUiTest { }` MUST NOT both appear in the same test. Use when the developer asks "how do I write a Compose test", "where do I declare state", "how do I name the test class", "MediumTest vs LargeTest", "rule.setContent inside @Before", or shows a test class that won't compile or doesn't drive state from outside.
