Did you consider using Emacs batch mode for re-indenting the source in bulk?
curious as to why you guys left Midje (I use clojure.test as well). What plugins/infrastructure were you missing?
For me, this is the essential bit: clojure.test is simpler and less magical. You can read the clojure.test source code and understand it in an hour or so - the trickiest bit is the extension system (e.g. throws?). Midje has a lot of really dark macro magic and the code is... complex.
