java – Spring MockMvc – 如何测试REST控制器的删除请求？

我需要测试我的控制器方法,包括删除方法.这是部分控制器代码：

@RestController
@RequestMapping("/api/foo")
public class FooController {

    @Autowired
    private FooService fooService;

    // other methods which works fine in tests

    @RequestMapping(path="/{id}", method = RequestMethod.DELETE)
    public void delete(@PathVariable Long id) {
        fooService.delete(id);
    }    
}

这是我的测试：

@InjectMocks
private FooController fooController;

@Before
public void setUp() {
    this.mockMvc = MockMvcBuilders.standaloneSetup(fooController)
.setControllerAdvice(new ExceptionHandler()).alwaysExpect(MockMvcResultMatchers.content().contentType("application/json;charset=UTF-8")).build();
}

@Test
public void testFooDelete() throws Exception {
    this.mockMvc.perform(MockMvcRequestBuilders
            .delete("/api/foo")
            .param("id", "11")
            .contentType(MediaType.APPLICATION_JSON))
            .accept(MediaType.APPLICATION_JSON))
            .andExpect(status().isOk());
}

因错误的状态代码而导致测试失败：

java.lang.AssertionError: Status
Expected :200 Actual :400

在控制台日志中我也发现了这个：

2017-12-11 20:11:01 [main] DEBUG o.s.t.w.s.TestDispatcherServlet - DispatcherServlet with name '' processing DELETE request for [/api/foo]
2017-12-11 20:11:01 [main] DEBUG o.s.w.s.m.m.a.RequestMappingHandlerMapping - Looking up handler method for path /api/foo

你能告诉我怎么解决吗？谢谢.

解决方法:

您的目标URI是：/ api / foo / 11基于此根：/ api / foo和此路径变量：/ {id}.

使用MockMvc时,您可以设置路径变量(也就是URI变量),如下所示：

delete(uri, uriVars)

更多细节in the Javadocs.

所以,你的测试应该是：

@Test
public void testFooDelete() throws Exception {
    this.mockMvc.perform(MockMvcRequestBuilders
            .delete("/api/foo/{id}", "11")
            .contentType(MediaType.APPLICATION_JSON))
            .accept(MediaType.APPLICATION_JSON))
            .andExpect(status().isOk());
}

或者：

@Test
public void testFooDelete() throws Exception {
    this.mockMvc.perform(MockMvcRequestBuilders
            .delete("/api/foo/11")
            .contentType(MediaType.APPLICATION_JSON))
            .accept(MediaType.APPLICATION_JSON))
            .andExpect(status().isOk());
}
