PyCharm does not support nose-testconfig and I need an alternative

I have most of test cases programmed using nose-testconfig, I'm trying to configure PyCharm in order to have a better IDE to improve my productivity but after investigating a lot an even ask to JetBrains I discovered PyCharm does not support nose-testconfig plugin then my ini file cannot be loaded before starting my test, so my test cannot be executed from PyCharm (I tried with external tool configuration but I could neither execute them, apparently same problem with config file "--tc-file=/home/iniFiles/884_firefox.ini") My question is if you know some method to use nose-testconfig with PyCharm, in the event it does not exist, what would you recommend me to do? I mean, is there any other unit test framework which allows ini config file (or similar format) and works in this way with PyCharm? I would like to have testing tool in pycharm, but most important to me is debugging functionality. I have a huge bunch of legacy test cases which I need to be able to use in PyCharm.

Thanks a lot for your help. Please let me know if I have not been clear enough
