Android-specific testing on a test-first foundation. This reference focuses on the test-first discipline plus the Compose-test and KMP traps that are easy to get wrong, not the basics of the three tiers, fakes over mocks, runTest, or Given-When-Then naming — except where a name breaks one target's compile.
This layers on top of any dedicated TDD discipline skill (superpowers:test-driven-development, ace:test-driven-development) but requires none. For bootstrapping the test stack from scratch (test DI, JUnit/Robolectric/Roborazzi/Paparazzi selection, the instrumented runner, Compose Preview Screenshot Testing, UI Automator, Jacoco), see Google's official testing-setup skill (android skills add testing-setup).
commonTest names must survive Kotlin/Native, not just the JVMcommonTest is compiled once per declared target, so a green jvmTest proves nothing about the iOS compile. Backticks themselves are fine on every target — they are escaping syntax, not part of the name — but Kotlin/Native's frontend rejects 24 characters inside them: . ; , ( ) [ ] { } / < > : \ $ & ~ * ? # | § % @ (FirNativeIdentifierChecker — an unconditional error since Kotlin 1.7; the set also reserves the IR mangler's own characters). Kotlin/JVM forbids only . ; [ ] / < > : \. The comma is the gap between the two lists; a space is in neither, so a Given-When-Then convention with commas fails every native target while CI stays green:
// commonTest — compiles for jvm; fails compileTestKotlinIosSimulatorArm64 with
// error: name contains illegal characters: ","
@Test fun `given an empty cart, when an item is added, then the total updates`() { … }
// commonTest — same sentence, commas dropped. Backticks and spaces compile everywhere.
@Test fun `given an empty cart when an item is added then the total updates`() { … }
Two rules follow. Keep , . ( ) : ? out of every commonTest declaration name — the check covers classes, properties, type aliases, value parameters and enum entries, not just funs. And verify a KMP test with allTests or <target>Test, never jvmTest, which depends only on compileTestKotlinJvm; a device-only target has no test task at all, so compile its test binary explicitly (linkDebugTestIosArm64).
Don't confuse this with the Android rule Kotlin's coding conventions cite: D8 rejects spaces below minSdk 30, which bites instrumented tests only — and never commas, which the DEX SimpleName grammar has never allowed at any API level.
StandardTestDispatchercreateComposeRule() / runComposeUiTest {} default to StandardTestDispatcher (matching kotlinx.coroutines.test.runTest) — there is no separate "v2" package. It's gated by androidx.compose.ui.test.ComposeUiTestFlags.isStandardTestDispatcherSupportEnabled (defaults to true), so the regular androidx.compose.ui.test.junit4.createComposeRule already uses it. To pin a scheduler, pass it through: createComposeRule(effectContext = StandardTestDispatcher()). Under this default, a LaunchedEffect that previously ran eagerly (the old UnconfinedTestDispatcher behaviour) may need an explicit mainClock.advanceTimeBy(0) / runCurrent() to drain queued work; set the flag false only to temporarily restore the legacy behaviour.
Two-schedulers trap (the one coroutine-test gotcha worth stating): a MainDispatcherRule's TestDispatcher and the dispatcher runTest { } creates have separate TestCoroutineSchedulers. Pass mainRule.dispatcher into runTest(mainRule.dispatcher) so Dispatchers.Main and the test body share one — otherwise advanceUntilIdle() flushes only one and assertions race the ViewModel.
testTag as fallbackPrefer user-visible semantics over testTag — real users and screen readers see semantics; testTag is invisible to everyone except tests. Selector priority: (1) onNodeWithText; (2) onNodeWithContentDescription; (3) role/state matchers (hasClickAction(), isSelected(), isFocused(), isEnabled()); (4) onNodeWithTag only when there's no stable user-visible text or it's duplicated/ambiguous (lists of identical rows, per-locale copy, multiple instances). A text assertion survives refactors and exercises accessibility; a testTag assertion breaks the moment the tag changes and misses the user-facing regression.
(Counterview worth knowing: skydoves/android-testing-skills argues tag-first for i18n robustness, backed by androidx/material3's own 1825 : 424 : 46 testTag : onNodeWithText : onNodeWithContentDescription ratio. Defensible if you have separate accessibility coverage; this skill defaults to semantics-first because it catches a class of bugs testTag never can.)
A composable's contract is "render state, emit callbacks" — test exactly that; don't route the assertion through a ViewModel mock.
@Test fun `tapping article row invokes onArticleClick with id`() {
var clickedId: String? = null
composeTestRule.setContent { ArticleRow(Article(id = "42", title = "Hello"), onArticleClick = { clickedId = it }) }
composeTestRule.onNodeWithText("Hello").performClick()
assertEquals("42", clickedId)
}
| Proving | Shape |
|---|---|
| Text rendered, conditional content, loading/error branches, callback wiring | Plain UI Compose test (state + callbacks, no graph) |
| Focus navigation, keyboard, TV/D-pad | Compose test with performKeyInput + assertIsFocused() (see compose/references/focus-navigation.md) |
| Visual contract semantics can't prove — spacing, themed colour, typography, elevation, gradients, skeletons | Screenshot test, one per meaningful state |
| State holder updates UI correctly | State-holder unit test + ONE wiring smoke test |
| Lifecycle, navigation, or DI integration itself | Integration test (createAndroidComposeRule, Hilt rule, real graph) |
Test clock vs wall clock: for any Compose-state-observable condition use mainClock.advanceTimeUntil(ms) { state.value == Done } (deterministic, fast); use rule.waitUntil(ms) { … } only for non-Compose conditions (Job.isCompleted, an external counter). Mixing the two in one test is a common flake source.
Animation tests need mainClock.autoAdvance = false set before setContent — otherwise the framework's InfiniteAnimationPolicy throws CancellationException on indeterminate animations, and finite animations finish in one auto-advanced burst with no observable intermediate state. After pausing, drive frames with advanceTimeByFrame() (kick-off) then advanceTimeBy(durationMillis).
Screenshot determinism: fixed state data (no current time, random seeds, or remote URLs in the screenshot path); frozen clocks (Clock.fixed(...)) and animation progress; a fake image loader for image-heavy screens (Coil 3's test double: LocalImageLoader provides FakeImageLoader(LocalContext.current), or setContentWithFakeImageLoader { … }); one shot per meaningful state (loading / error / success / empty), not one per UI element.

# Android Testing
Android-specific testing on a **test-first** foundation. This reference focuses on the test-first discipline plus the Compose-test and KMP traps that are easy to get wrong, not the basics of the three tiers, fakes over mocks, `runTest`, or Given-When-Then naming — except where a name breaks one target's compile.
## Test-first (the foundation)
- **No production code without a failing test first.** Write the test, watch it fail (RED), write the minimal code to pass (GREEN), then refactor. A behaviour you never watched fail isn't proven.
- **A bug isn't fixed until a test that was red *because of the bug* is green.**
This layers on top of any dedicated TDD discipline skill (`superpowers:test-driven-development`, `ace:test-driven-development`) but requires none. For *bootstrapping* the test stack from scratch (test DI, JUnit/Robolectric/Roborazzi/Paparazzi selection, the instrumented runner, Compose Preview Screenshot Testing, UI Automator, Jacoco), see Google's official [`testing-setup`](https://github.com/android/skills/tree/main/testing/testing-setup) skill (`android skills add testing-setup`).
## `commonTest` names must survive Kotlin/Native, not just the JVM
`commonTest` is compiled once **per declared target**, so a green `jvmTest` proves nothing about the iOS compile. Backticks themselves are fine on every target — they are escaping syntax, not part of the name — but Kotlin/Native's frontend rejects 24 characters *inside* them: `. ; , ( ) [ ] { } / < > : \ $ & ~ * ? # | § % @` ([`FirNativeIdentifierChecker`](https://github.com/JetBrains/kotlin/blob/master/compiler/fir/checkers/checkers.native/src/org/jetbrains/kotlin/fir/analysis/native/checkers/FirNativeIdentifierChecker.kt) — an unconditional error since Kotlin 1.7; the set also reserves the IR mangler's own characters). Kotlin/JVM forbids only `. ; [ ] / < > : \`. **The comma is the gap between the two lists; a space is in neither**, so a Given-When-Then convention with commas fails every native target while CI stays green:
```kotlin
// commonTest — compiles for jvm; fails compileTestKotlinIosSimulatorArm64 with
// error: name contains illegal characters: ","
@Test fun `given an empty cart, when an item is added, then the total updates`() { … }
// commonTest — same sentence, commas dropped. Backticks and spaces compile everywhere.
@Test fun `given an empty cart when an item is added then the total updates`() { … }
```
Two rules follow. Keep `,` `.` `(` `)` `:` `?` out of every `commonTest` declaration name — the check covers classes, properties, type aliases, value parameters and enum entries, not just `fun`s. And **verify a KMP test with `allTests` or `<target>Test`, never `jvmTest`**, which depends only on `compileTestKotlinJvm`; a device-only target has no test task at all, so compile its test binary explicitly (`linkDebugTestIosArm64`).
Don't confuse this with the Android rule Kotlin's coding conventions cite: D8 rejects *spaces* below `minSdk` 30, which bites instrumented tests only — and never commas, which the DEX `SimpleName` grammar has never allowed at any API level.
## Compose tests now default to `StandardTestDispatcher`
`createComposeRule()` / `runComposeUiTest {}` default to `StandardTestDispatcher` (matching `kotlinx.coroutines.test.runTest`) — **there is no separate "v2" package.** It's gated by `androidx.compose.ui.test.ComposeUiTestFlags.isStandardTestDispatcherSupportEnabled` (defaults to `true`), so the regular `androidx.compose.ui.test.junit4.createComposeRule` already uses it. To pin a scheduler, pass it through: `createComposeRule(effectContext = StandardTestDispatcher())`. Under this default, a `LaunchedEffect` that previously ran eagerly (the old `UnconfinedTestDispatcher` behaviour) may need an explicit `mainClock.advanceTimeBy(0)` / `runCurrent()` to drain queued work; set the flag `false` only to temporarily restore the legacy behaviour.
**Two-schedulers trap** (the one coroutine-test gotcha worth stating): a `MainDispatcherRule`'s `TestDispatcher` and the dispatcher `runTest { }` creates have **separate** `TestCoroutineScheduler`s. Pass `mainRule.dispatcher` into `runTest(mainRule.dispatcher)` so `Dispatchers.Main` and the test body share one — otherwise `advanceUntilIdle()` flushes only one and assertions race the ViewModel.
## Semantics first, `testTag` as fallback
Prefer user-visible semantics over `testTag` — real users and screen readers see semantics; `testTag` is invisible to everyone except tests. Selector priority: (1) `onNodeWithText`; (2) `onNodeWithContentDescription`; (3) role/state matchers (`hasClickAction()`, `isSelected()`, `isFocused()`, `isEnabled()`); (4) `onNodeWithTag` **only** when there's no stable user-visible text or it's duplicated/ambiguous (lists of identical rows, per-locale copy, multiple instances). A text assertion survives refactors and exercises accessibility; a `testTag` assertion breaks the moment the tag changes and misses the user-facing regression.
*(Counterview worth knowing: [skydoves/android-testing-skills](https://github.com/skydoves/android-testing-skills) argues tag-first for i18n robustness, backed by androidx/material3's own 1825 : 424 : 46 `testTag` : `onNodeWithText` : `onNodeWithContentDescription` ratio. Defensible if you have separate accessibility coverage; this skill defaults to semantics-first because it catches a class of bugs `testTag` never can.)*
## Callbacks as test surfaces
A composable's contract is "render state, emit callbacks" — test exactly that; don't route the assertion through a ViewModel mock.
```kotlin
@Test fun `tapping article row invokes onArticleClick with id`() {
var clickedId: String? = null
composeTestRule.setContent { ArticleRow(Article(id = "42", title = "Hello"), onArticleClick = { clickedId = it }) }
composeTestRule.onNodeWithText("Hello").performClick()
assertEquals("42", clickedId)
}
```
## Choosing the test shape — the smallest contract that proves the behaviour
| Proving | Shape |
|---|---|
| Text rendered, conditional content, loading/error branches, callback wiring | Plain UI Compose test (state + callbacks, no graph) |
| Focus navigation, keyboard, TV/D-pad | Compose test with `performKeyInput` + `assertIsFocused()` (see `compose/references/focus-navigation.md`) |
| Visual contract semantics can't prove — spacing, themed colour, typography, elevation, gradients, skeletons | Screenshot test, one per meaningful state |
| State holder updates UI correctly | State-holder unit test + ONE wiring smoke test |
| Lifecycle, navigation, or DI integration itself | Integration test (`createAndroidComposeRule`, Hilt rule, real graph) |
**Test clock vs wall clock:** for any Compose-state-observable condition use `mainClock.advanceTimeUntil(ms) { state.value == Done }` (deterministic, fast); use `rule.waitUntil(ms) { … }` only for non-Compose conditions (`Job.isCompleted`, an external counter). Mixing the two in one test is a common flake source.
**Animation tests need `mainClock.autoAdvance = false` set *before* `setContent`** — otherwise the framework's `InfiniteAnimationPolicy` throws `CancellationException` on indeterminate animations, and finite animations finish in one auto-advanced burst with no observable intermediate state. After pausing, drive frames with `advanceTimeByFrame()` (kick-off) then `advanceTimeBy(durationMillis)`.
**Screenshot determinism:** fixed state data (no current time, random seeds, or remote URLs in the screenshot path); frozen clocks (`Clock.fixed(...)`) and animation progress; a fake image loader for image-heavy screens (Coil 3's test double: `LocalImageLoader provides FakeImageLoader(LocalContext.current)`, or `setContentWithFakeImageLoader { … }`); one shot per meaningful state (loading / error / success / empty), not one per UI element.
