title: Force retesting or disable test caching
body: <p><strong>Problem:</strong></p>
  
  <p>When I run the same go test twice the second run is not done at all. The results are the cached ones from the first run.</p>
  
  <pre><code>PASS    
  ok      tester/apitests    (cached)
  </code></pre>
  
  <p><strong>Links</strong></p>
  
  <p>I already checked <a href="https://golang.org/cmd/go/#hdr-Testing_flags" rel="noreferrer">https://golang.org/cmd/go/#hdr-Testing_flags</a> but there is no cli flag for that purpose.</p>
  
  <p><strong>Question:</strong></p>
  
  <p><strong>Is there a possibility to force go test to always run test and not to cache test results.</strong></p>
