mockito

问题 I am writing an integration test using mockito. The unit under test is connected to a mocked object (objA) through an interface. The functionality that I am trying to mimic happens when the mocked objected fires an event and the unit under test is listening to it. The interface: public interface MyInterfaceAPI{ void fireyMyEvent(String msg); } The unit under test: public class UnitUnderTest{ ObjA objA; public UnitUnderTest(ObjA objA_t) { objA = objA_t; objA.addMyListener(new addMyHandler());

问题 In Kotlin (and Java 8) we can use Lambda expression to remove boilerplate callback interface. For example, data class Profile(val name: String) interface ProfileCallback { fun onSuccess(profile: Profile) } class ProfileRepository(val callback: ProfileCallback) { fun getProfile() { // do calculation callback.onSuccess(Profile("name")) } } We can change remove ProfileCallback and change it into Kotlin's Lambda: class ProfileRepository(val callback: (Profile) -> Unit) { fun getProfile() { // do

问题 I'm testing a service layer and not sure how to mock ObjectMapper().readValue in that class. I'm fairly new to mockito and could figure out how to do it. The following is my code, service.java private configDetail fetchConfigDetail(String configId) throws IOException { final String response = restTemplate.getForObject(config.getUrl(), String.class); return new ObjectMapper().readValue(response, ConfigDetail.class); } ServiceTest.java @Test public void testgetConfigDetailReturnsNull() throws

问题 I want to write unit tests for my spring controller. I'm using keycloak's openid flow to secure my endpoints. In my tests I'm using the @WithMockUser annotation to mock an authenticated user. My problem is that I'm reading the userId from the token of the principal. My unit test now fails because the userId I read from the token is null; if (principal instanceof KeycloakAuthenticationToken) { KeycloakAuthenticationToken authenticationToken = (KeycloakAuthenticationToken) principal;

问题 I am writing a unit test for a FizzConfigurator class that looks like: public class FizzConfigurator { public void doFoo(String msg) { doWidget(msg, Config.ALWAYS); } public void doBar(String msg) { doWidget(msg, Config.NEVER); } public void doBuzz(String msg) { doWidget(msg, Config.SOMETIMES); } public void doWidget(String msg, Config cfg) { // Does a bunch of stuff and hits a database. } } I'd like to write a simple unit test that stubs the doWidget(String,Config) method (so that it doesn't

问题 I want to create a mocked list to test below code: for (String history : list) { //code here } Here is my implementation: public static List<String> createList(List<String> mockedList) { List<String> list = mock(List.class); Iterator<String> iterHistory = mock(Iterator.class); OngoingStubbing<Boolean> osBoolean = when(iterHistory.hasNext()); OngoingStubbing<String> osHistory = when(iterHistory.next()); for (String history : mockedList) { osBoolean = osBoolean.thenReturn(true); osHistory =

问题 I am trying to Test a method but it has a global variable which is null, Please guide me so I can assign value to global variable i.e. a Map My Junit: public class ErrorTest { @Mock private DataSource db; @Mock private JdbcTemplate jdbcTemplate; @InjectMocks private RateServiceImpl rateService = new RateServiceImpl(); @Mock private RaterDao raterDao; @Resource private MessageSource msg ; @Mock Map<String, StringAttribute> errorMap = new HashMap<String, StringAttribute>(); @Before public void

问题 I am trying to do a unit test on this code : Bundle cidParam(String accountId) { Bundle params = new Bundle(1); params.putString(Params.CID, accountId); return params; } This is the unit test : private void mockBundle(String cid) throws Exception { Bundle mBundle = PowerMockito.mock(Bundle.class); PowerMockito.doNothing().when((BaseBundle)mBundle).putString(AnalyticsController.Params.CID, cid); } However, it always returns: java.lang.RuntimeException: Method putString in android.os.BaseBundle

问题 I have written a simple method which should take a url and retrieve the data from this url via a get request. The method looks like this: public String getResponse(String connectionUrl) throws HttpException { HttpURLConnection connection = null; try { URL url = new URL(connectionUrl); connection = (HttpURLConnection) url.openConnection(); connection.setRequestMethod("GET"); int responseCode = connection.getResponseCode(); if (responseCode != 200) { throw new HttpException("Response code was "
