Good day. Visual Studio 2015 Community Edition Update 3 is available.
Installed via NuGet nUnit 2.6.4 and nUnitTestAdapter 2.0.
When you run a unit test, in the Output window, the Tests tab, you can see that the tests are located and run. By commands to perform unsuccessful tests and run the passed tests, you can even understand whether the tests have passed or not. That is, if the test passed, when running failed tests, the message No tests to run, etc. appears in the console.
However, the Test Explorer does not show anything at all.
