Test Explorer in Visual Studio 2022 is not working

Question

When I click Run All tests in view, it's running but not showing that tests are passed or failed. I mean it's showing blue marks as shown before]

Answer 1

Try invoking them by running the command in console

dotnet test

If that doesn't help it could be that the NUnit 3 Test Adapter is missing and you need to reinstall it.

I also suggest you to view the error output of your test runner to get some more information by opening the output panel (by clicking on view-->output), then choosing "tests" (from the 'Show output from' dropdown) and you'll get the specific problem.
