Built tests are not added to the Visual Studio Test Explorer window

Question

1. I set up the SpecFlow plug-in for the Visual Studio 2013.
2. I created new Feature Item and build it.

Result: built test is not shown in the Test

Answer 1

I'm running SpecFlow tests with SpecRunner and had this same problem, a couple of times as a matter of fact. Having tried all of the above suggestions, I found that the only solution to the problem was to uninstall and reinstall the SpecRun NuGet package. Next build, tests present in Test Explorer window as expected.
