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

In my case all the approaches above didn't work. My solution: I don't know why, but - I re-installed "Specflow for Visual Studio 2015" in "Tools => Extensions and Updates", then I've created a new feature file (old still didn't work), and this new feature-file works correctly.
