title: In Azure DevOps, can you get the test results in another Stage - namely total tests run/passed/failed/ignored?
body: <p>I have an Azure DevOps pipeline running in YAML.</p>
  
  <p>I'm using the VSTest@2 task to execute some unit tests. This is all working fine and I see the test results appear in the Stage overview UI itself, and in the 'Tests and Coverage' overview in the header.</p>
  
  <p>My YAML pipeline also posts a message to a Slack channel with links to the build, success/failure status and other things. I'm keen to add Test results into the message too...just a simple 'Total tests X - Passed X - Failed X - Skipped X' display. This happens in a separate Stage at the end.</p>
  
  <p>Is there a way to get the tests results from a previous stage in a later stage in the pipline (running on a different agent)?</p>
  
  <p>Are the tests available as an artifact, and if so where are they and in what format?</p>
  
  <p>Would I be right in thinking the only way to do this is via the Azure API? (I can't really be bothered to setup auth with that in the pipeline just for this feature, I don't interact with the API yet anywhere else)</p>
