        lateinit var backendApi:BackendApi

    lateinit var fakeAuthRepository: FakeAuthRepository
    lateinit var authRepository: AuthRepository
    private lateinit var viewModel: SignInViewModel
    @Before
    fun setUp() {

        MockitoAnnotations.initMocks(this)
        fakeAuthRepository = FakeAuthRepository(backendApi)
        authRepository = AuthRepository(backendApi)
        viewModel = SignInViewModel(authRepository)

    }

    var login = _login

    @Test
    fun `testing repository`() = runBlockingTest {

        val fake = fakeAuthRepository.login("[email protected]", "12345678", "android", "123455")
        val real = authRepository.login("[email protected]", "12345678", "android", "123455")
        assertEquals(fake, real)


    }

CodePudding user response：

@Before is junit4 annotation.

If you are using junit5 you have to replace it with @BeforeEach.
