Gonna have to disagree yet again.

As an example, the Bacula project requires a database to run, and has a
full suite of testing stuff that multiple people run to help find bugs.
The thing that makes it doable is the fact that the setup process is
documented well enough that anyone who can follow instructions can set
up a testing system.
