DejavuComposeTestRule

class DejavuComposeTestRule<A : ComponentActivity>(delegate: AndroidComposeTestRule<ActivityScenarioRule<A>, A>) : ComposeContentTestRule(source)

A test rule that wraps AndroidComposeTestRule with automatic Dejavu lifecycle management. Enables Dejavu and resets recomposition counts before each test, so no @Before boilerplate is needed.

Constructors

constructor(delegate: AndroidComposeTestRule<ActivityScenarioRule<A>, A>)

Properties

activity

val activity: A

Provides access to the underlying activity instance.

density

open override val density: Density

mainClock

open override val mainClock: MainTestClock

Functions
