How to create the vsmdi/testrunconfig file when importing a Visual Studio test project?

Question

When I add an existing test project, my solution lacks the vsdmi and the testrunconfig files. How to create it?

Answer 1

In Visual Studio 2010 just go to Test → Create New Test List...

It will automatically add the vsdmi file and put it into the correct location, no need to add a solution item manually.
