Running Unit test in PHPStorm, but not showing the web response

I've decided to give Test Driven Development a try. So far, so good, however while developing an API for my site, I do run into the problem that the test is false so now and than. Once the test fails, only little information is provided for example:

Expected status code 200 but received 422. Failed asserting that false is true.

It also gives the line of the test that failed, however it does not give the response of the API. In this case 422 is a valid JSON response, without exceptions. The JSON response is that the user needs to provide a email/password in order to login.

I already found on this forums that you can export the logs to the command line by adding the following line to web.php (it is a kind of hack... but well)

Log::useFiles( 'php://stderr' );

Now my question is: Is it possible to show the webresponse in the command line when the test fails?

I'm using Laravel 5.4
