DevRecT1 - Fixture setup for testing (and potentially dev setup)

[TheMadBug]

Best to wait on #1126
Also maybe on #1166 - so that each main module would have its own fixture set

Create full set of fixures that can be used for testing - or even development.

Need to work out if we migrate existing test plans / leave existing test plans as is / start fresh etc
Also write a few more test plans to make sure fixture is comprehensive

I usually try and compress all the data migrations every so often. Might be easier to dump SQL into CSV then write them out
