PDS & Feedgen: Testing things that require a database connection

[rudyfraser]

Mainly looking to solve the fact that tests are failing in the CI after deployment due to some tests requiring a database connection. Open to this being a mock database connection of some kind -- will need a way to have records created I think during tests but no persisting after tests complete. Folks doing dev work could hopefully not have to manually set up a bunch of services to be able to build and test things.

I'm going to take a look into this this weekend, if all works out the way I expect it to!
