Why is [AssemblyInitialize] and [AssemblyCleanup] being called twice in same test project assembly?

Question

I thought the whole purpose of these attributes was to run them only once per assembly. I have a simple class as follows:

[TestClass]
public class AssemblyIntegr         


        

Answer 1

In my case, it was a misbehavior of QTAgent32.exe process that was causing [AssemblyInitialize] to be executed twice. Restarting the host machine where my code was built and executed solved the issue for me.
