[galaxy-dev] Writing functional test for galaxy tools

Dear Galaxy development team, I am working with Gunnar Raetsch's group in Tuebingen and now I am writing functional test for mGene modules in our galaxy instance. Here my tools will automatically create an output directory and write all output files into that. The tool will keep most of its output files behind the galaxy screen. User will be able to see a summary file for his/her experiment. So my question is simple. Whether do you have any system to perform a functional test for such kind of situations? I would like to hear from you. Many thanks, Vipin T S
