QOF is actually pretty well covered already, but there’s plenty to work on in src/engine.

Be sure to read http://wiki.gnucash.org/wiki/Testing . There’s a StackOverflow article here
that lists several “beginning unit-testing” books. Mind 1) that some of the Gnucash classes are rather
impervious to testing and 2) that we’ve departed a bit from the “best practice” of writing a
separate function for each assert in the interest of getting more coverage in a hurry. I’ve found
the strategies in http://www.amazon.com/Working-Effectively-Legacy-Michael-Feathers/dp/0131177052
very helpful in figuring out how to test spaghetti functions, but like all CS books, it’s expensive.
 There’s an executive summary at
that you might find useful.

When you’re ready (and have the money), http://www.amazon.com/xUnit-Test-Patterns-Refactoring-Code/dp/0131495054
is the reference to get and keep handy.
