Question

我只是想检查用户是否使用异步方法创建，我是测试新手，所以我正在使用ArgumentCaptor检查onRegistrationSucces()回调是否被调用过1次检查它是否成功。

这就是我所做的测试

RegisterTest.kt

@Test
    fun should_SignUpUser(){
        presenter.signUp("test1","test1@gmail.com","asdasd")
        verify(interactor).createUserWithEmailAndPassword("test1","test1@gmail.com","asdasd",object: RegisterInteractor.RegisterCallBack{
            override fun onRegistrationSucces() {
                callbackCaptor.capture()
            }

            override fun onRegistrationFailure(errorMsg: String) {
                callbackCaptor.capture()
            }
        })
        verify(callbackCaptor.value.onRegistrationSucces(), times(1))
    }

这是我要测试的演示者方法

RegisterPresenter.kt

override fun signUp(fullName:String, email: String, password: String) {
        view?.showProgress()
        registerInteractor.createUserWithEmailAndPassword(fullName,email, password, object : RegisterInteractor.RegisterCallBack {

                override fun onRegistrationSucces() {
                    if(isViewAttached()){
                        view?.navigateToLogin()
                        view?.hideProgress()
                    }
                }

                override fun onRegistrationFailure(errorMsg:String) {
                    if(isViewAttached()){
                        view?.showError(errorMsg)
                        view?.hideProgress()
                    }
                }

            })
    }

但是我遇到了这个错误

参数不同！通缉： interactor.createUserWithEmailAndPassword（ “ test1”， “ test1@gmail.com”， “ asdasd”， com.testapp.presentation.register.presenter.RegisterPresenterTest$should_SignUpUser$1@c86b9e3 ）; -> com.testapp.presentation.register.presenter.RegisterPresenterTest.should_SignUpUser（RegisterPresenterTest.kt：119）实际调用具有不同的参数： interactor.createUserWithEmailAndPassword（ “ test1”， “ test1@gmail.com”， “ asdasd”， com.testapp.presentation.register.presenter.RegisterPresenter$signUp$1@10aa41f2 ）; -> com.testapp.presentation.register.presenter.RegisterPresenter.signUp（RegisterPresenter.kt：64）

Answer 1

inner class below:          

class CallbackRegister extends RegisterInteractor.RegisterCallBack {  
private View view;
private Object forViewattached;     

public CallbackRegister(Object forViewattached, View view){
this.forViewattached=forViewattached;
this.view = view;
}

 override fun onRegistrationSucces() {
                    if(forViewattached.isViewAttached()){
                        view?.navigateToLogin()
                        view?.hideProgress()
                    }
                }

                override fun onRegistrationFailure(errorMsg:String) {
                    if(forViewattached.isViewAttached()){
                        view?.showError(errorMsg)
                        view?.hideProgress()
                    }
                }


//end class
}


Access this by the  kotlin equivalent:

object : new CallbackRegister(forViewattached, view)   

instead of object: RegisterInteractor.RegisterCallBack{...}

you can easily test this by:   TopLevelClass.CallbackRegister callbackRegisterUnderTest = new TopLevelClass().new CallbackRegister(MockforViewattached, MockView);

You can now call the callback methods directly and verify the mocks:

callbackRegisterUnderTest.onRegistrationSucces()
verify the mocks did something.
You have to convert this to kotlin, but I hope you see what is happening.

问题在于，每个createuserwithemailandpasswords方法的回调都不同。这就是为什么您看到“参数不同”错误的原因。

使用以下命令正确捕获回调：

verify(interactor).createUserWithEmailAndPassword(anyString(),anyString(),anyString(),callbackCaptor.capture())
            verify(callbackCaptor.value.onRegistrationSucces(), times(1))

如果您要验证字符串，可以用唯一的字符串捕获器替换anyString。

ArgumentCaptor-参数不同

RegisterTest.kt

RegisterPresenter.kt
