Why Test crashes using NUnit / TestDriven.Net2.0?

I have a Set of TestFixtures running fine. I added a new Test into the fixture, but for some reason, I am not able to run it. Other tests in other classes and even in the same class run fine.

• Both NUnit GUI / TestDriven crash

If I run from NUnit GUI I get this error:

NUnit has stopped Working with this message

using TestDriven.Net 2.0 inside VS2008, get this error:

Well, it seems fairly clear that you're causing a stack overflow. StackOverflowException is a fatal exception which will bring down the CLR - which is why you're seeing that problem.

I suggest you debug into the test to work out the cause of the stack overflow. It's typically a recursion issue. For example, if you have a typo in a property:

 private readonly int age;

 public int Age
 {
     get { return Age; } // should be "return age;"
 }

That will cause a stack overflow - but so can incautiously written recursive methods.
