createzopecoverage ================== createzopecoverage provides a ``bin/createzopecoverage`` script that serves as a one-line coverage report generator. It is essentially a wrapper around `z3c.coverage <http://pypi.python.org/pypi/z3c.coverage>`_. It is intended for use inside buildouts, so there are two assumptions: - The directory you run this script from is the root of the buildout. - There is a ``bin/test``. And yes, it assumes a z3c.coverage, so a zope test setup. It doesn't work with a "regular" coverage.py setup. Installation and use -------------------- To install, add ``createzopecoverage`` to a zc.recipe.egg section. You often already have one for common scripts. So something like this:: [buildout] ... parts = ... console_scripts [console_scripts] recipe = zc.recipe.egg eggs = ... createzopecoverage alternatively you may use:: [buildout] ... parts = ... createzopecoverage [createzopecoverage] recipe = createzopecoverage (Note: you can name your part differently and the binary will be named after that part). This gives you a ``bin/createzopecoverage`` script that does the following: - Check whether bin/test exists. Safety feature. - Remove old coverage dir if it exists. This way you always have clean results. - Run bin/test with the ``--coverage=...`` option. - Use z3c.coverage to create the actual reports. By default into ``./coverage/reports``. If you start createzopecoverage with a command line argument (``bin/createzopecoverage /tmp/output``) it will put the reports into that directory. - Open the reports in your webbrowser *if you did not specify an output directory*. The assumption here is that if you run the script as-is, you just want to see the coverage reports. If you *do* specify an output directory, you're probably running it from within buildbot or so on the server and you want the output in some webserver-served directory. No use to open a browser on the server. Development ----------- The source code lives at https://bitbucket.org/reinout/createzopecoverage, you can also `report issues <https://bitbucket.org/reinout/createzopecoverage/issues>`_ there. Feel free to suggest improvements (and especially to make them yourself). OSX comment ----------- z3c.coverage uses the "enscript" command for python code highlighting. The version provided by OSX before 10.5.7 complains about an unkown ``--footer`` argument passed by z3c.coverage. There are two possible solutions: - Update to 10.5.7. That update came out a few minutes after I wrote this original comment :-) - Install enscript from macports. - Add a script called "enscript" on your path that calls the original enscript minus the offending argument:: #!/bin/sh shift /usr/bin/enscript -q --header -h --language=html --color -o - $9 More info --------- Technical details and a full doctest are in ``createzopecoverage/USAGE.txt``.
