Android &引用；需要0个匹配器，记录了3个"；-为什么需要0个匹配者？

这个问题以前有人问过，但现有的答案并不完全适用于我的情况

我想测试

submitCode（）

方法：

public class VerificationCodeViewModel{

    //Input
    public final ObservableField<String> verificationCode           = new ObservableField<>();

    //Output
    public final ObservableField<String> requestError               = new ObservableField<>();
    public final ObservableBoolean loading                          = new ObservableBoolean();
    public final ObservableField<LoginCredentials> loginCredentials = new ObservableField<>();

    @NonNull private final Context context;
    @NonNull private final UnverifiedUser unverifiedUser;
    @NonNull private final CampaignRepository campaignRepository;
    @NonNull private final AccountRepository accountRepository;
    @NonNull private final VerificationCodeNavigator navigator;

    public VerificationCodeViewModel(@NonNull Context context,
                                     @NonNull UnverifiedUser unverifiedUser,
                                     @NonNull CampaignRepository campaignRepository,
                                     @NonNull AccountRepository accountRepository,
                                     @NonNull VerificationCodeNavigator navigator) {

        this.context = context;
        this.unverifiedUser = unverifiedUser;

        this.campaignRepository = campaignRepository;
        this.accountRepository = accountRepository;
        this.navigator = navigator;
    }

    public void submitCode() {

        loading.set(true);

        String sourceCampaign = null;
        if (campaignRepository.getCampaign() != null) {
            sourceCampaign = campaignRepository.getCampaign().getSource();
        }

        this.accountRepository.verifyMobileNumber(
                this.unverifiedUser,
                this.verificationCode.get(),
                sourceCampaign,
                new AccountDataSource.VerifyMobileNumberCallback() {
                    @Override
                    public void onVerificationSuccess(UnverifiedUser.Entity entity) {
                        loading.set(false);
                        loginCredentials.set(createLoginCredentials());
                        navigator.finishActivity(true);
                    }

                    @Override
                    public void onVerificationFailure(@Nullable String message) {
                        loading.set(false);
                        requestError.set(message);
                    }
                }
        );
    }
}

AccountRemoteDataSource.java

public class AccountRepository implements AccountDataSource {
    @Override
    public void verifyMobileNumber(@NonNull UnverifiedUser unverifiedUser, 
                                   @NonNull String verificationCode, 
                                   @Nullable String sourceCampaign, 
                                   @NonNull VerifyMobileNumberCallback callback) {
        this.remoteSource.verifyMobileNumber(unverifiedUser, verificationCode, sourceCampaign, callback);
    }
}

public class AccountRemoteDataSource implements AccountDataSource {

    @Override
    public void verifyMobileNumber(@NonNull UnverifiedUser unverifiedUser,
                                   @NonNull String verificationCode,
                                   @Nullable String sourceCampaign,
                                   @NonNull final VerifyMobileNumberCallback callback) {

        accountService().verifyMobileNumber(/*params*/).enqueue(new Callback() {
            @Override
            public void onResponse(Response response, Retrofit retrofit) {
                try{
                    //parse response
                    callback.onVerificationSuccess(entity);
                } catch (Exception e) {
                    callback.onVerificationFailure(e.getMessage());
                }
            }

            @Override
            public void onFailure(Throwable t) {
                callback.onVerificationFailure(t.getMessage());
            }
        });
    }
}

哈哈，找到了！您在测试文件的第六个注释字段中错误地使用了

@Mock ArgumentCaptor

@Mock private ArgumentCaptor<AccountDataSource.VerifyMobileNumberCallback>
    verifyMobileNumberCallbackCaptor;

@Mock private ArgumentCaptor，然后对Mockito Mock的下一次调用将触发验证。Mockito在参数匹配器堆栈上看到三个匹配器，用于调用
capture
。这就是为什么记录了3个匹配者，预期为0

将注释切换到，您就可以开始了。
您确定错误在那一行吗？张贴整个错误please@JuanCruzSoler我已经包含了完整的错误消息，并在代码段中标记了相关行。感谢您迄今为止提供的完整且标记良好的源代码，但除此之外，请发布
verifyMobileNumber
的实现。很有可能是
最终版
；AccountRepository和verifyMobileNumber

都应该是非最终版本。（我有点惊讶它说的是“记录了3个匹配者”而不是“记录了4个匹配者”，但0预期是一个相当不错的信号，表明你没有验证你认为你是什么。）@JeffBowman谢谢！我已经包括了实现

AccountRepository

是

viewModel

中的

final

字段（删除

final

并不能解决问题）

AccountRepository

、

remoteSource

和

verifyMobileNumber（）

都不是

final

Facepalm！当然，现在一切都有意义了。非常感谢您抽出时间来发现这一点

@Mock private ArgumentCaptor<AccountDataSource.VerifyMobileNumberCallback>
    verifyMobileNumberCallbackCaptor;
