buildout recipe for installing Selenium RC
This weekend at the Plone Naples Sprint one of the things I worked on was a buildout to download and install Selenium RC. It is now available from PYPI under the name collective.recipe.seleniumrc For some reason the Selenium RC distribution zip file contains version numbers on each subdirectory so this meant I couldn't just use one of the existing download scripts. But I didn't want to re-invent the download recipe wheel, so I decided to base this recipe on a well-written existing download recipe, hexagonit.recipe.download. I asked on IRC if the author was present at the sprint and ironically enough he was sitting in the same room as me only two rows away ;) With some simple changes to his recipe I was able to derive collective.recipe.seleniumrc from it and gain features like download caching and md5 file hash verification. Along the way I learned that if you want your buildout recipe to be derived by others you should make it a new-style Python class so that super() works. Also that it helps to factor your install() method into submethods for overriding. The changes I made to hexagonit.recipe.download were cleaned up and integrated into a 1.1.0 release that we made yesterday, along with the 0.1 release of collective.recipe.seleniumrc If you want to try out the Selenium RC recipe just create a simple buildout.cfg:
