i'm using mockito and junit and run unit test against spring mvc my flow of code is:
Service Layer -> Model Layer -> Controller Layer
i was successfully testing the Controller against the model layer with the code:
@RunWith(MockitoJUnitRunner.class)
public class HashLinkerControllerTest {
private static final Logger LOGGER = Logger
.getLogger(HashLinkerControllerTest.class);
@Mock
private HashLinkerModel modelMock;
@InjectMocks
private HashLinkerController controller;
private MockMvc mockMvc;
@Before
public void setup() {
MockitoAnnotations.initMocks(this);
this.mockMvc = MockMvcBuilders.standaloneSetup(controller).build();
}
@Test
public void update() throws Exception {
int date = 123;
String hashToCheck = "asdfasdfasdfasdfas";
HashLinker first = this.createHashLinker(hashToCheck, "some name",
"some des", "some data", date);
when(modelMock.update(first)).then(returnsFirstArg());
mockMvc.perform(
put("/api/hashService/" + hashToCheck)
.contentType(TestUtil.APPLICATION_JSON_UTF8)
.content(
TestUtil.convertObjectToJsonBytesWithSettersOnly(first))
.accept(TestUtil.APPLICATION_JSON_UTF8))
.andExpect(status().isOk())
.andExpect(
content().contentType(TestUtil.APPLICATION_JSON_UTF8))
.andExpect(jsonPath("$.hash", is(hashToCheck)))
.andExpect(jsonPath("$.description", is("some des")))
.andExpect(jsonPath("$.name", is("some name")));
verify(modelMock, times(1)).update(first);
verifyNoMoreInteractions(modelMock);
}
but now i'm looking for a way to test the 3 layers structure. i.e testing the service against the controller . i came up with :
@RunWith(MockitoJUnitRunner.class)
public class HashLinkerControllerServiceLayerTest {
private static final Logger LOGGER = Logger
.getLogger(HashLinkerControllerServiceLayerTest.class);
@Mock
private HashLinkerService serviceMock;
@InjectMocks
// @Mock
private HashLinkerModel modelMock;
private HashLinkerController controller;
private MockMvc mockMvc;
@Before
public void setup() {
MockitoAnnotations.initMocks(this);
controller = new HashLinkerController(modelMock);
this.mockMvc = MockMvcBuilders.standaloneSetup(controller).build();
}
and doing the test with
@Test
public void update() throws Exception {
int date = 123;
String hashToCheck = "asdfasdfasdfasdfas";
HashLinker first = this.createHashLinker(hashToCheck, "some name",
"some des", "some data", date);
when(serviceMock.update(first)).then(returnsFirstArg());
mockMvc.perform(
put("/api/hashService/" + hashToCheck)
.contentType(TestUtil.APPLICATION_JSON_UTF8)
.content(
TestUtil.convertObjectToJsonBytesWithSettersOnly(first))
.accept(TestUtil.APPLICATION_JSON_UTF8))
.andExpect(status().isOk())
.andExpect(
content().contentType(TestUtil.APPLICATION_JSON_UTF8))
.andExpect(jsonPath("$.hash", is(hashToCheck)))
.andExpect(jsonPath("$.description", is("some des")))
.andExpect(jsonPath("$.name", is("some name")));
verify(serviceMock, times(1)).update(first);
verifyNoMoreInteractions(serviceMock);
}
the test is the same as above expect i have changed modelMock to be serviceMock. for some reason this test fails . i get 404.
any ideas?
