Only real file with changes worth looking at, all the rest is adding tags to spec files.

As discussed here rubyforgood#4264, some tests modify global variables and expect them to be reset before each test. This makes it more difficult to move forward with removal of pre-seeding. This commit refactors certain tests to be less brittle to changes in global state and to rely less on assumptions on global state. Ex: not assuming that there are 0 records of a certain type when a test starts, etc.

* fix: remove more test order dependence As discussed here #4264, some tests modify global variables and expect them to be reset before each test. This makes it more difficult to move forward with removal of pre-seeding. This commit refactors certain tests to be less brittle to changes in global state and to rely less on assumptions on global state. Ex: not assuming that there are 0 records of a certain type when a test starts, etc. * fix: minor cleanup / lint

You can reorganize this a bit like so:
if seeded_last && !seed_current
DatabaseCleaner.clean_with(:truncation) # remove previously seeded data
end
if seed_current
seed_base_data_for_tests if !seeded_last # need to re-seed data
define_global_variables
end

I was doing it the other way do be explicit about all the cases, also why I added the comment about the !seeded && !seeded case. You think this is better?
All specs tagged with seed_db will get seeded. This happens on a group level, so it will happen before the whole group. Ex: if the outer most Rspec.describe is tagged with seed_db: true the seeding will run once before the entire spec file and once after. Tracks the previous execution group. - seed or not seed base on flag on current group - truncate if the previous group seeded
Previously we were truncating if prev run had been seed and seeding if current run needed seeding. The more correct approach is: if seeded_last && seed_this => only define global vars if seeded_last && !seed_this => truncate if !seeded_last && seed_this => seed + define globals if !seed_last && !seed_this => do nothing

@dorner ill rebase the other existing PRs off this. You think its possible if I get the refactors in early enough to get this done before the event? |

Can't hurt to try! 🎉 |

New change in item seeding strategy:
All specs are seeded by default except specs tagged with
