@fleeting-xx I suspect the right medium to long term solution here would be to convert these tests to unit tests, as @ChuanqiXu9 suggested. This would avoid having to mess around with the config file using `sed` since all of that set up could be done programatically.

Thanks @zmodem for the short term fix!
