What is "Could not find Test Containers for requested projects" message in VS output window?

Question

When I build my VS2015 solution I'm getting "Could not find Test Containers for requested projects" in my output window. It's in the "Tests" output---which is getting displayed automatically on publishing my (MVC) projects.

This has only started happening recently.

I have some MSTest projects in the solution.

I'm using Resharper. I mention this as the only search hits I got on the message were pages about Resharper.

What do these messages mean and, more importantly, how do I get rid of them?

I have VS 14.0.25431.01 Update 3 and Resharper 2016.2.2.

Answer 1

Seems like the best solution currently is to disable MSTest support in Resharper.

Go to Resharper | Options | Tools | Unit Testing | MsTest and uncheck Enable MSTest support.

Solved the problem for a few people, but obviously disables the MSTest support you get with Reshaper. So, we have to decide on the lessor of two evils for now.

Answer 2

I got rid of mine by

1. Navigating to Help | Register Product
2. Sign Out
3. Sign In

I have no idea why this worked for me, and no real good reason to have tried it in the first place.

Answer 3

As for me if i published in debug configuration - everything was ok. But with release i had the same problem. Next steps helped me: - Switched to Release configuration - Clean/rebuild solution - Publish it
