Based on the SQLIntegrityConstraintViolationException it looks like your delete statements are not being executed, do you perhaps have two delete. Sql files or not have src/test/resources configured as a source location in Eclipse?
What I've noticed that sometimes my unit test outputs change depending on the level of sandboxing done by the used testing tool. For example Eclipse seems to sandbox current selection(class, package, project) to a single setup-test-teardown cycle in same context while our CI seems to sandox every single unit test as setup-test-teardown cycle.
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.
