We have commit rights to the SVN repository.

I believe you can do that with Ned Batchelder's coverage.py if you include 'coverage' in your eggs list in buildout.cfg and run the tests as bin/coverage run bin/test [options as usual] bin/coverage xml Downside: Hudson runs the steps as a shell script with 'set -e' enabled, which means that the first command that fails stops the script. You won't get coverage results if your tests fail. (Also, if ztk tests fail, zopeapp tests won't even be run). The syntax for combining coverage files produced by several test runs is left as an exercise for the reader: http://nedbatchelder.com/code/coverage/cmd.html > At that point, the build process would be nicely automated, with > browsable results including coverage, pretty graphs, etc. See the > 'repoze' jobs for examples of those outputs. Nice. Incidentally, I recommend the "green balls" plugin that I see you're already using for hudson.repoze.org. Blue doesn't really signal "job was successful" to me. > Questions for discussion: > > - I find the prettier interface and easier setup than buildbot worth > running a 3rd-party Java app (rather than a 3rd party Python app). > Would that be acceptable among the folks running our automated tests? A year ago I'd have said "there will be no PHP or Java on my servers". A month ago I installed Hudson because Buildbot finally got to me. I'm still holding the fort against PHP, though ;) > - Is it worth adding the XML support for test results and coverage to > 'zope.testing.testrunner'? I think so, at least for the test results. > - Would people be willing to run Hudson "permanently" on enough hosts > to make this a reasonable replacement for buildbot (we need Windows, > too)? I'd have to overcome my paranoia of letting somebody else define what shell commands get run on my servers, but it seems enough people are already providing Linux build slaves. > - Hudson seems general purpose enough to allow automating other code- > related tasks, e.g., production of dependency graphs.

It would be *awesome* if people making releases of core packages like zope.interface didn't need to build Windows binary eggs by themselves. > I will try to leave the ZTK Hudson server up for a little bit, to allow > folks to see what it can deliver already. > >  http://hudson-ci.org/ > >  http://hudson.repoze.org/ > >  http://old.nabble.com/schema-for-junit-xml-output-td22193385.html > >  http://cobertura.sourceforge.net/xml/coverage-01.dtd Regards, Marius Gedminas -- http://pov.lt/ -- Zope 3 consulting and development
