I recently encountered the same error, and instead of using MockMVC I created an integration test as follows:
<pre><code>@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@ContextConfiguration(classes = { MyTestConfiguration.class })
public class MyTest {
 
 @Autowired
 private TestRestTemplate testRestTemplate;
 
 @Test
 public void myTest() throws Exception {
 
 ResponseEntity&lt;String&gt; response = testRestTemplate.getForEntity(&quot;/test&quot;, String.class);
 
 assertEquals(HttpStatus.INTERNAL_SERVER_ERROR, response.getStatusCode(), &quot;unexpected status code&quot;);
 
 } 
}
</code></pre>
and
<pre><code>@Configuration
@EnableAutoConfiguration(exclude = NotDesiredConfiguration.class)
public class MyTestConfiguration {
 
 @RestController
 public class TestController {
 
 @GetMapping(&quot;/test&quot;)
 public ResponseEntity&lt;String&gt; get() throws Exception{
 throw new Exception(&quot;not nice&quot;);
 } 
 } 
}
</code></pre>
this post was very helpful: <a href="https://github.com/spring-projects/spring-boot/issues/7321" rel="nofollow noreferrer">https://github.com/spring-projects/spring-boot/issues/7321</a>

I want to assert that an exception is raised and that the server returns an 500 internal server error.

To highlight the intent a code snippet is provided:

<pre><code>thrown.expect(NestedServletException.class);
this.mockMvc.perform(post("/account")
 .contentType(MediaType.APPLICATION_JSON)
 .content(requestString))
 .andExpect(status().isInternalServerError());
</code></pre>

Of course it dosen't matter if I write <code>isInternalServerError</code> or <code>isOk</code>.
The test will pass regardless if an exception is thrown below the <code>throw.except</code> statement.

How would you go about to solve this?

我想断言引发了一个异常，并且服务器返回了一个500内部服务器错误。为了突出这一意图，提供了一个代码片段：thrown.expect(NestedServletException.class);this.mockMvc.perform(post("/account")            .contentType(Me...
