title: @AutoConfigureWebTestClient(timeout = "600000") has no effect
body: <p>I'm using <code>WebTestClient</code> to do some integration testing of a controller. If I set a breakpoint inside the controller I hit the standard timeout of 5s of the <code>WebTestClient</code>. The solution to this is to add <code>@AutoConfigureWebTestClient(timeout = "600000")</code> to my test as stated her <a href="https://stackoverflow.com/a/49496309/671639">Timeout on blocking read for 5000 MILLISECONDS in Spring WEBFLUX</a>.</p>
  
  <p>For me <code>@AutoConfigureWebTestClient(timeout = "600000")</code> does not change anything. I still get the timout exception after 5s.</p>
  
  <p>Any ideas what's wrong?</p>
  
  <pre><code>@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
  @ActiveProfiles("test")
  @Transactional
  @Import(EntityFactoryConfiguration.class)
  @AutoConfigureWebTestClient(timeout = "600000") // giv me 10 min for debugging
  public class LogControllerIntegrationTest {
  
      ...
  
      @Autowired
      private WebTestClient webTestClient;
  
      ...
  
      @Test
      public void myTest() {
          ...
          webTestClient.post().uri("/log")
                  .contentType(MediaType.APPLICATION_JSON_UTF8)
                  .accept(MediaType.APPLICATION_JSON_UTF8)
                  .body(BodyInserters.fromObject(protocolLine))
                  .exchange()
                  .expectStatus().isOk();
  
      }
  </code></pre>
