模拟静态方法时出现内容类型错误

Question

我正在尝试测试控制器内的方法。如果我在我正在测试的方法中调用的静态方法中注释掉逻辑，则测试通过。

我不能评论那个逻辑，相反我只想嘲笑它。现在模拟工作了，但我收到如下新错误：

java.lang.AssertionError: Content type not set

但我确实有指示的内容类型。请告知我做错了什么。

@Test
public void testMethod() throws Exception{

    // If I don't mock this, test will fail. 
    // If I don't mock this comment out logic in this method, test passes. 
    // If I mock this, test passes if I don't check for content type.
    // I am using Power Mockito. 

    mockStatic(MyStaticClass.class);
    doReturn("").when(MyStaticClass.class, "someMethod", any(Config.class), anyString());

    //also tried this, works. 
    //when(MyStaticClass.someMethod(any(Config.class), anyString())).thenReturn("");


    //as mentioned above this would work if I comment out logic in MyStaticClass. 
    mockMvc.perform(
                get("/api/some/a/b/c/d").accept(
                        MediaType.APPLICATION_JSON))
                .andExpect(status().isForbidden())
                .andExpect(content().contentType("text/html")); // when I mock, I need to comment this out to get test to work.  
}



// Controller 

@RequestMapping(value = "/{a}/{b}/{c}", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE) // I do have content type
@ResponseBody
public MyResponse getSomething(
            HttpServletRequest request, HttpServletResponse response,
            @PathVariable String a, @PathVariable String b,
            @PathVariable String c,
            @RequestParam(value = "some", required = false) String some)
            throws Exception {

            // some logic 

            //static method being called
            MyStaticClass.someMethod("sample", "sample2");

            try {
                MyResponse myPageResponse = new MyResponse(anotherStr, someStr); // it breaks here and throws that error msg. Doesn't reach return.
                return MyResponse;
            } catch (NullPointerException npe) {}
}

Answer 1

这是一个没有 body 的获取请求，因此理想情况下使用 contentType("text/html") 指定 content-type header 可能不是正确的方法。第二您在请求中的 content-type header 必须与 @consumes 值匹配，它清楚地表明您希望发送 text/html 但没有 @consumes 支持它。
