使用Mockito的Android单元测试

Question

@RunWith(MockitoJUnitRunner.class)
public class RegisterMemberPresenterTest {
    @Mock
    private  RegisterModel mRegisterModel;
    @Mock
    private  VerifyModel mVerifyModel;
    @Mock
    private  RegisterMemberContract.View mView;
    @Mock
    private  RegisterMemberPresenter mRegisterMemberPresenter;
    @Before
    public void setUp() throws Exception {
        MockitoAnnotations.initMocks(this);
    }
    @Test
    public void check_validPassword(){
        mRegisterMemberPresenter = new RegisterMemberPresenter(mRegisterModel,mVerifyModel,mView);
         mMemberPresenter.validPassword2("","123");
      verify(mView).setPasswordValidation(false, "error");
      mMemberPresenter.validPassword2("123","");
      verify(mView).setPassword2Validation(false, "error");
      mMemberPresenter.validPassword2("123","123");
      verify(mView).setPassword2Validation(true, null);
      mMemberPresenter.validPassword2("123","456");
      verify(mView).setPassword2Validation(false, "error");
    }
}

我对此测试有问题。

在第四次测试中应该是"密码不相同"，但是当我运行测试时它仍然通过。

我知道视图有问题，因为当我将第四测试移至第一个测试时它将显示错误消息，告诉我正确的是"密码不同的"非错误"。

public void validPassword2(String pwd, String pwd2) {
    if (pwd.isEmpty()) {
        mView.setPasswordValidation(false, "error");
        return;
    }
    if (pwd2.isEmpty()) {
        mView.setPassword2Validation(false, "error");
        return;
    }
    if (pwd.equals(pwd2)) {
        mView.setPassword2Validation(true, null);
    } else {
        mView.setPassword2Validation(false, "password is not same");
    }
}

验证(模拟(调用之间有一些干扰。

测试应仅出于一个原因而失败，因此您应该将测试分为单个测试。

之类的东西

@RunWith(MockitoJUnitRunner.class)
public class RegisterMemberPresenterTest {
    @Mock
    private  RegisterModel mRegisterModel;
    @Mock
    private  VerifyModel mVerifyModel;
    @Mock
    private  RegisterMemberContract.View mView;
    @Mock
    private  RegisterMemberPresenter mRegisterMemberPresenter;
    @Before
    public void setUp() throws Exception {
        MockitoAnnotations.initMocks(this);
        mRegisterMemberPresenter = new RegisterMemberPresenter(mRegisterModel,mVerifyModel,mView);
    }
    @Test
    public void check_validPassword_blankFirstPassword(){
         mMemberPresenter.validPassword2("","123");
         verify(mView).setPasswordValidation(false, "error");
    }
    @Test
    public void check_validPassword_blankSecondPassword(){
         mMemberPresenter.validPassword2("123","");
         verify(mView).setPassword2Validation(false, "error");
    }
    @Test
    public void check_validPassword_validMatchingPasswords(){
         mMemberPresenter.validPassword2("123","123");
         verify(mView).setPassword2Validation(true, null);
    }
    @Test
    public void check_validPassword_nonMatchingPasswords(){
         mMemberPresenter.validPassword2("123","456");
         verify(mView).setPassword2Validation(false, "error");
    }
}
