title: Undefind withoutExceptionHandling()
body: <p>I'm trying to run my UnitTest on laravel 6 (windows 10) with the famous:  </p>
  
  <blockquote>
    <p>this->withoutExceptionHandling();</p>
  </blockquote>
  
  <p>But I get this error:</p>
  
  <blockquote>
    <p>Error: Call to undefined method Tests\Unit\ExampleTest::withoutExceptionHandling()</p>
  </blockquote>
  
  <p>I didn't change any setting and of course it's being defined in: </p>
  
  <blockquote>
    <p>Illuminate\Foundation\Testing\Concerns\InteractsWithExceptionHandling</p>
  </blockquote>
  
  <p>I even tried: </p>
  
  <blockquote>
    <p>"use Illuminate\Foundation\Testing\Concerns\InteractsWithExceptionHandling;" </p>
  </blockquote>
  
  <p>But this still does nothing.</p>
