This question has been asked before but the existing answers don't quite apply to my situation.
I'd like to test the submitCode() method:
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);
}
}
);
}
}
I have the following test case:
public class VerificationCodeViewModelTests {
private VerificationCodeViewModel viewModel;
@Mock private Context context;
@Mock private UnverifiedUser unverifiedUser;
@Mock private CampaignRepository campaignRepository;
@Mock private AccountRepository accountRepository;
@Mock private VerificationCodeNavigator navigator;
@Mock private ArgumentCaptor<AccountDataSource.VerifyMobileNumberCallback> verifyMobileNumberCallbackCaptor;
@Before
public void setupVerificationCodeViewModel(){
MockitoAnnotations.initMocks(this);
viewModel = new VerificationCodeViewModel(
context,
unverifiedUser,
campaignRepository,
accountRepository,
mock(VerifyMobileNumberActivity.class)//navigator
);
}
@Test
public void testSubmitCode(){
viewModel.verificationCode.set(VERIFICATION_CODE);
viewModel.submitCode();
assertTrue(viewModel.loading.get());
verify(accountRepository).verifyMobileNumber(
eq(unverifiedUser),//line 132
eq(VERIFICATION_CODE),//line 133
eq(CAMPAIGN_SOURCE),//line 134
verifyMobileNumberCallbackCaptor.capture());//line 135
UnverifiedUser.Entity entity = mock(UnverifiedUser.Entity.class);
when(entity.getId()).thenReturn(ENTITY_ID);
verifyMobileNumberCallbackCaptor.getValue().onVerificationSuccess(entity);
assertFalse(viewModel.loading.get());
assertEquals(viewModel.loginCredentials.get().getUsername(),UNVERIFIED_USER_EMAIL);
assertEquals(viewModel.loginCredentials.get().getPassword(),UNVERIFIED_USER_PASSWORD);
verify(navigator).finishActivity(true);
}
}
When I verify that the accountRepository.verifyMobileNumber is invoked, I get the following error:
org.mockito.exceptions.misusing.InvalidUseOfMatchersException: Invalid use of argument matchers! 0 matchers expected, 3 recorded: -> at ...testSubmitCode(VerificationCodeViewModelTests.java:132) -> at ...testSubmitCode(VerificationCodeViewModelTests.java:133) -> at ...testSubmitCode(VerificationCodeViewModelTests.java:134)
This exception may occur if matchers are combined with raw values: //incorrect: someMethod(anyObject(), "raw String"); When using matchers, all arguments have to be provided by matchers. For example: //correct: someMethod(anyObject(), eq("String by matcher"));
For more info see javadoc for Matchers class.
at ...VerificationCodeViewModelTests.testSubmitCode(VerificationCodeViewModelTests.java:135)
What I do not understand is why does it say 0 matches expected? Other answers suggest replacing eq(..) with any(...) or isA(..).
Firstly, I don't believe that's applicable because the error is that no matchers are expected in the first place;
and secondly, I've tried it and the issue persists.
I'd be grateful if someone could explain why 0 matchers are expected and how to fix this problem.
Update
The implementation of AccountRepository.verifyMobileNumber() is:
AccountRepository.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);
}
}
AccountRemoteDataSource.java
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());
}
});
}
}
