I have been handed a complex set of Ant scripts for feature additions and maintenance. No test framework whatsoever has been used for developing those in the past. I want to start developing the new features inside tests. The scripts use a mix of ant, ant contrib and custom made tasks, I am not going to be adding any new tasks, just scripts. How do I go about building unit tests around those? I looked at AntUnit but it seems more concerned with unit testing custom task development.
