title: Vstest.console.exe can't find nunit tests
body: <p>I have VS 2017 and .net 4.6 </p>
  
  <p>On trying to run via cmd prompt using vstest.console:</p>
  
  <pre><code>vstest.console.exe bin\Release\Tests.dll /UseVsixExtensions:true
  </code></pre>
  
  <p>I am getting warning "No test is available in <code>/bin/Release/test.dll</code> Make sure that installed test discoverers &amp; executors, platform &amp; framework version settings are appropriate and try again."</p>
  
  <p>So, I tried listing the tests but it doesn't show any tests.</p>
  
  <pre><code>vstest.console.exe bin\Release\Tests.dll /ListTests /UseVsixExtensions:true
  </code></pre>
  
  <p>Unit tests class file is as shown below.</p>
  
  <pre><code>[TestFixture]
  public class class1
      {
      static void StartTest(string[] args)
      {
  
      }
  
   [Test] [Category("Regression_Test")]   
      public void TS1()
      {
  
      }
  }
  </code></pre>
  
  <p>I tried googling for similar issue but didn't find anything that would work. Any help is really appreciated</p>
