 Description   

When running controller tests against endpoints that are asynchronous and using the PrintResultHandler, my tests always fail because the PrintResultHandler seems to attempt to print the result before it is available.

When the endpoint is asynchronous, I would expect that we wait to print until asyncDispatch(mvcResult) gets called or waiting some period of time before the result becomes available.

Example Code

final MvcResult mvcResult = getMockMvc().perform(post(<ASYNC_ENDPOINT>))
                    .andExpect(request().asyncStarted())
                    .andExpect(request().asyncResult(instanceOf(WebResponse.class)))
                    .andReturn();

getMockMvc().perform(asyncDispatch(mvcResult))
                    .andExpect(status().isOk());

Stack Trace

java.lang.IllegalStateException: Async result for handler [public <HIDDEN>] was not set during the specified timeToWait=0
