How to use Microsoft.VisualStudio.TestPlatform.TestExecutor in Unit Test App?

I want to test my DLL for Universal App in Visual Studio 2015 (OS: Windows 10). I find Unit Test App project template in C# category:

This creates another new App for me, in which, there is a Test class with TestMethod. I tried to run the Test app but I don't think the method is invoked and I don't where to look for the test results.

Anyone have had experience?
