Coroutines

Coroutines (Work-in-Progress)

Mockito-Kotlin supports stubbing and verifying with suspendable functions (those marked with suspend). This is possible without the need to create a coroutine context, e.g. using runTest {} from kotlinx.coroutines.test.

As of Mockito-Kotlin 6.2.0, the core whenever and KStubbing APIs support calling suspend functions directly:

whenever { myMock.suspendFoo() } doReturn value
mock<MyClass> {
  on { suspendFoo() } doReturn value
}

Use verifyBlocking to verify suspendable functions:

verifyBlocking(myMock) { suspendFoo() }
