Testing open source isn't a new area of expertise (of course), and there are some methods and tools available which make it easier to put in perspective. One of these methods is the
Open Source Maturity Model (OSMM).
This website is dedicated to this subject, and can certainly help provide a methodical background to the testing and QA process.
There's also some ISO standard (
ISI 9126) that classifies tests for applications.
