}

the function impletation
@test
fun given init state , when SaveAccountInfoUseCase fail , then SubmissionError state should be emit() {
// arrange
val accountInfo = fakePresentationAccountInfo()
saveAccountInfoUseCaseReturnFail()
// act
subject.saveAccountInfo()
// assert
val submissionError = AccountUiState.SubmissionError(accountInfo, "error")

Truth.assertThat(subject.uiUiState.value)
    .isInstanceOf(AccountUiState.SubmissionError::class.java)

}

the the code is
fun saveAccountInfo() {
val accountInfo = _uiState.value.accountInfo
disposable += saveAccountInfoDataUseCase.execute(
accountInfo.fromPresentationToDomain()
)

I have the same issue when using disposable +=. Please note that the test is flaky, sometimes it passes, sometimes it fails with the exception io.mockk.MockKException: can't find stub Disposable(temporary mock)
