MockMvc在测试Web层时为null。

英文:

MockMvc is null when testing the Web Layer

问题

我在我的应用程序中有这个MvcTest:

@SpringBootTest
@WebMvcTest
public class BarsControllerTest {

	@Autowired
	private MockMvc mockMvc;

	@Test
	public void testBars() throws Exception {

		mockMvc.perform(get("/bars")
				.contentType(MediaType.APPLICATION_JSON_UTF8_VALUE))
				.andExpect(status().isOk())
				.andExpect(jsonPath("$.length()", is(1)));
	}
}

但是当我运行测试时,mockMvc在运行测试时为null。

英文:

I have this MvcTest in my application:

@SpringBootTest
@WebMvcTest
public class BarsControllerTest {

	@Autowired
	private MockMvc mockMvc;



	@Test
	public void testBars() throws Exception {

		mockMvc.perform(get("/bars")
				.contentType(MediaType.APPLICATION_JSON_UTF8_VALUE))
				.andExpect(status().isOk())
				.andExpect(jsonPath("$.*", hasSize(1)));
	}
}

but when I run the test mockMvc is null when running the tests.

不应该同时使用 @WebMvcTest@SpringBootTest

如果你想要测试 Web 层和其他层,可以同时使用 @AutoConfigureMockMvc@SpringBootTest

@SpringBootTest
@AutoConfigureMockMvc
public class BarsControllerTest {

    @Autowired
    private MockMvc mockMvc;

    @Test
    public void testBars() throws Exception {

        mockMvc.perform(get("/bars")
                .contentType(MediaType.APPLICATION_JSON_UTF8_VALUE))
                .andExpect(status().isOk())
                .andExpect(jsonPath("$.*", hasSize(1)));
    }
}

或者,如果你只想测试 Web 层,可以只使用 @WebMvcTest,请注意这不会加载完整的 Spring 应用程序上下文(它只加载 Web 层):

@WebMvcTest
public class BarsControllerTest {

    @Autowired
    private MockMvc mockMvc;

    @Test
    public void testBars() throws Exception {

        mockMvc.perform(get("/bars")
                .contentType(MediaType.APPLICATION_JSON_UTF8_VALUE))
                .andExpect(status().isOk())
                .andExpect(jsonPath("$.*", hasSize(1)));
    }
}
英文:

You shouldn't use @WebMvcTest and @SpringBootTest together.

If you want to test both web layer and other layers Use @AutoConfigureMockMvc and @SpringBootTest together:

@SpringBootTest
@AutoConfigureMockMvc
public class BarsControllerTest {

    @Autowired
    private MockMvc mockMvc;



    @Test
    public void testBars() throws Exception {

        mockMvc.perform(get("/bars")
                .contentType(MediaType.APPLICATION_JSON_UTF8_VALUE))
                .andExpect(status().isOk())
                .andExpect(jsonPath("$.*", hasSize(1)));
    }
}

Or if you only want to test web layer you can use just @WebMvcTest: note the this does not load full spring application context(It only loads web layer)

@WebMvcTest
public class BarsControllerTest {

    @Autowired
    private MockMvc mockMvc;



    @Test
    public void testBars() throws Exception {

        mockMvc.perform(get("/bars")
                .contentType(MediaType.APPLICATION_JSON_UTF8_VALUE))
                .andExpect(status().isOk())
                .andExpect(jsonPath("$.*", hasSize(1)));
    }
}
