Of the several maintained backends, only two (Launchpad and Allura) have automated tests, and those are limited, and written in different ways. So I suggest we:
put test data for all backends into the tests/data/ directory
write tests for the data-processing parts of all maintained backends, using Python's unittest framework (could also use Mock and nose)
port the Launchpad tests to use the standard framework instead of having to download data from the web each time
