How can Spock be made to retry failed Geb tests?

You'd have to write a little JUnit rule (for example something like gist.github.com/897229 ) or Spock extension. You'd probably have to live with some limitations like the same spec instance being reused and JUnit just reporting a single test, but hopefully nothing that rules out the approach altogether. (One thing that comes to mind is that mocking might not work.) In a future version of Spock, repeating a test (or its building blocks) will likely become a first-class concept, doing away with these limitations.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
