wxPyCoverage is a simple source browser that shows which lines of code have and have not been executed, by accepting the output from trace.py and updating the code display as the program executes. To run it, redirect the output from your program to the input of wxPyCoverage, thusly: trace.py --trace yourCode.py | ./wxPyCoverage.py wxPyCoverage will accept input from stdin indefinitely, expecting that it's in the format output by trace.py, i.e.: file.py(line): text file.py(line): text file.py(line): text --- modulename: etc... file.py(line): text file.py(line): text file.py(line): text etc. This was written using Python 2.4, but should work with whatever versions print trace output in that format. It was also written using wxPython 2.6.x, and uses that to allow interactive browsing of the source code. It was tested on SuSE Linux 10.1. If you're using this on Windows, and have issues, please let me know; (I don't have a Windows box handy to do my own testing). Enjoy, Dave (djaquay@users.sourceforge.net)
