title: Parallel TestNG Results in IntelliJ are mixed up
body: <p>I am running tests in parallel with TestNG (v6.14.3, desclared as a dependeny in pom file) and IntelliJ (2018.1.1). </p>
  
  <p>The tests are run on 3 browsers FF, Chrome and IE. I have some logs/println of test steps in the console, but the results are not quite clear, structure of result on each browser is a bit messed up, as following screenshot:</p>

  <p>For example, when I choose test on Firefox, the output is empty, so I don't see my outputs. But when I click on the root BKMS_FileUpload, all outputs for all 3 browsers are there and mixed up, so it's hard to say what is what.</p>
  
  <p>I expect that the ouputs should be printed separatedly for each browser. I don't know if I am missing something. This is my testng.xml</p>
  
  <pre><code>&lt;suite name="BKMS_FileUpload" parallel="tests"&gt;
  &lt;listeners&gt;
      &lt;listener class-name="ScreenShotListener" /&gt;
  &lt;/listeners&gt;
  &lt;test name="FileUpload Performance Test Firefox"&gt;
      &lt;parameter name="browser" value="Firefox"/&gt;        
      &lt;classes&gt;
          &lt;class name="FileUploadPerformanceTest"/&gt;
      &lt;/classes&gt;
  &lt;/test&gt;
  &lt;test name="FileUpload Performance Test Chrome"&gt;
      &lt;parameter name="browser" value="Chrome"/&gt;        
      &lt;classes&gt;
          &lt;class name="FileUploadPerformanceTest"/&gt;
      &lt;/classes&gt;
  &lt;/test&gt;
  &lt;test name="FileUpload Performance Test IE11"&gt;
      &lt;parameter name="browser" value="IE" /&gt;        
      &lt;classes&gt;
          &lt;class name="FileUploadPerformanceTest" /&gt;
      &lt;/classes&gt;
  &lt;/test&gt;
  &lt;/suite&gt;
