Hi Sunny,

Are you able to get a debugger onto the code before it hangs? NCrunch has no knowledge of the behaviour of Nancy's test code - it will simply call into it. If there is a difference in the behaviour of the code under test, usually you should be able to identify this by debugging through.

There is some history with people using Nancy under NCrunch, so it is possible that there are overrides in place to detect NCrunch and introduce alternative behaviour.

The timeout enforcement by NCrunch and underlying test frameworks is not 100% reliable. The interruptions triggered by timeouts are handled using Thread.Abort, which will not trigger aborts under certain situations. This makes it possible for the execution thread to hang inside some piece of O/S critical code and be unrecoverable without the test process being torn down.
