How to run tests in VS2015 for a Unity project?

Question

Unity

I have a large piece of game logic in the project, without display, which I would like to cover with tests using "Microsoft.VisualStudio.TestTools.UnitTesting". But, unfortunately, there is no such namespace in the standard Unity project. Tell me how to run tests in the IDE?

Answer 1

Create a separate project in the same solution, connect your current one to it as a dependency and write tests.
Naturally, classes covered by tests should not contain unity uses, otherwise use something else for tests.
