Howto resolve .net test hangs on “Starting test execution, please wait…”

Question

I am trying to execute dotnet test from the command line on our Jenkins build server, but it just hangs on:

Starting test execution, please wait...

Answer 1

Sometimes xUnit tests hang forever because the test runner pipeline can't handle parallel threads.

To check if that's the issue try adding xunit.runner.json file to the tests project root

  
    
      Always
    
  

And put inside 1 thread config.

{
  "parallelizeTestCollections": true,
  "maxParallelThreads": -1
}
