Do you put unit tests in same project or another project?

Question

Do you put unit tests in the same project for convenience or do you put them in a separate assembly?

If you put them in a separate assembly like we do, we end up wit

Answer 1

As others have answered - put tests in separate projects

One thing that hasn't been mentioned is the fact that you can't actually run nunit3-console.exe against anything but .dll files.

If you're planning on running your tests via TeamCity, this will pose a problem.

Let's say you have a console application project. When you compile, it returns an executable .exe to the bin folder.

From the nunit3-console.exe you wouldn't be able to run any tests defined in that console application.

In other words, a console application returns an exe file and a class library returns dll files.

I just got bit by this today and it sucks :(
