That's such an unhelpful and arrogant response. I was looking for suggestions on why 'while' loop with an exit clause should timeout. In the unit tests provided it didn't timeout, clearly an infinate loop is not caused in those test conditions.
I've had feedback from others that has been more help and so I don't need your assistance any further.

I am getting the same problem reported by others, execution timeout when trying Attempt only. Are there further tests cases anyone can suggest for testing speed of tests?

I like how easy this is to read, compared to the others I've seen so far.
