How can I test MutableSharedFlow<Unit>() with turbine ?

[ismailtosun]

Hi,
when i press button MutableSharedFlow() is emiting. So how can i test this with turbine emiting or not ?

// in ViewModel
private val _updateAddress = MutableSharedFlow()
val updateAddress = _updateAddress.asSharedFlow()

fun updateAddressClick() {
viewModelScope.launch {
_updateAddress.emit(Unit)
}
}

//Test Class
@test
fun updateAddressBtn_clickEvent_Emiting_or_Not() = runTest {
viewModel.updateAddress.test {
// given
// when
viewModel.updateAddressClick()
// then
Truth.assertThat(awaitEvent())
}
}

What you wrote looks fine. There is no real way to test the absence of an emission since your code could emit an item a millisecond later. All you can assert in the negative is that no events have been seen up until the current point in time.
