I am new to JUnit and Mockito. Can someone please guide how to mock the below rest template? My current mocking shows an error: Unfinished Stubbing.
Service
class MyService { void func(){ (SimpleClientHttpRequestFactory).restTemplate.getRequestFactory()).setConnectTimeout(t1); } } Mockito
Class MyTest { @Inject MyService service; @Mock RestTemplate template; @Test void testit(){ doNothing().when((SimpleClientHttpRequestFactory) .restTemplate.getRequestFactory())).setTimeout(anyInt(); } } You need to add initMocks() or openMocks() for mock initialisation like that:
@BeforeEach(for Junit5 @Before for Junit4) void setUp(){ initMocks(this); } And then you should declare your mocks behavior in the "when-then" section:
when(restTemplate.getRequestFactory()).thenReturn(mock(RequestFactory.class)); Use mockito for stubbing chain of invocation your methods.
Full version example:
Class MyTest { @Inject MyService service; @Mock RestTemplate template; @BeforeEach void setUp(){ initMocks(this); } @Test void testit(){ RestTemplate template = mock(RestTemplate.class); ClientHttpRequestFactory factory = mock(ClientHttpRequestFactory.class); when(restTemplate.getRequestFactory()).thenReturn(template)); when(template.getRequestFactory).thenReturn(factory); etc... } }
