I'm trying to decide whether I want to run wordpress off SVN or just grab the latest stable release. I'm making this decision because it seems that the repository is seeing a lot of development action (a good thing for bugfixes and new features).
However, I'm also concerned about using Subversion, because I don't know much about how you guys deal with QA and unit testing. Specifically, I'd like to know what kind of QA or unit testing you guys do, or if you do any at all before committing changes to the repository?
Obviously, there is no guarantee with any software that nothing will break between builds, even in releases, but can you shed some light / statistics on exactly how stable the nightly builds are (as well as SVN)-- how many times things have gone awry in the past between commits, etc.
