Nunit 3 isn't running tests, while I'm running tests with 2.64 everything works like a charm. on version 3, I'm not getting any errors or anything. it just won't run.
I'm running my tests with Selenium-C# and Appium.
I never use Selenium-C# and Appium but common problem is if You start using NUnit 3 is NUnit Test Adapter.
NUnit Test Adapter for previous version of NUnit 2 won't work, test don't appear in test explorer etc.
To solve this You must install a NUnit 3 Test Adapter.
Here is a link for package:
