const val DEFAULT_TIMEOUT_MS = 10000: Long

The default timeout applied when calling runMainLooperUntil. This timeout should be sufficient for any condition using a Robolectric test.

java-static fun createRobolectricConditionVariable(): ConditionVariable!

Creates a ConditionVariable whose block method times out according to wallclock time when used in Robolectric tests.

java-static fun runLooperUntil(looper: Looper!, condition: Supplier<Boolean!>!): Unit

Runs tasks of the looper until the condition returns true.

Must be called on the thread corresponding to the looper.

Note for androidx.media3.test.utils.FakeClock users: If the condition changes outside of a message on this Looper, for example because it's checking a volatile variable or shared synchronized state that is updated on a background thread, or because checking the condition itself may cause it to become true, then the remainder of the test method may be executed in parallel with other background thread messages.

java-static fun runLooperUntil(
    looper: Looper!,
    condition: Supplier<Boolean!>!,
    timeoutMs: Long,
    clock: Clock!
): Unit

Runs tasks of the looper until the condition returns true.

Must be called on the thread corresponding to the looper.

Note for androidx.media3.test.utils.FakeClock users: If the condition changes outside of a message on this Looper, for example because it's checking a volatile variable or shared synchronized state that is updated on a background thread, or because checking the condition itself may cause it to become true, then the remainder of the test method may be executed in parallel with other background thread messages.

java-static fun runMainLooperUntil(condition: Supplier<Boolean!>!): Unit

Runs tasks of the main Robolectric Looper until the condition returns true.

Must be called on the main test thread.

Note for androidx.media3.test.utils.FakeClock users: If the condition changes outside of a main Looper message, for example because it's checking a volatile variable or shared synchronized state that is updated on a background thread, or because checking the condition itself may cause it to become true, then the remainder of the test method may be executed in parallel with other background thread messages.

java-static fun runMainLooperUntil(
    condition: Supplier<Boolean!>!,
    timeoutMs: Long,
    clock: Clock!
): Unit

Runs tasks of the main Robolectric Looper until the condition returns true.

Must be called on the main test thread.

Note for androidx.media3.test.utils.FakeClock users: If the condition changes outside of a main Looper message, for example because it's checking a volatile variable or shared synchronized state that is updated on a background thread, or because checking the condition itself may cause it to become true, then the remainder of the test method may be executed in parallel with other background thread messages.
