I think the name "transactional fixtures" is a little misleading and confusing, because (as far as I can tell) it doesn't really have anything to do with fixtures.

This is pretty embarrassing, but I've been using Rails almost since 1.0 and I had no idea that transactional fixtures were running on my tests. I don't use fixtures so I just erroneously assumed that feature didn't work for me. I've been using Database Cleaner unnecessarily for like the last four years. I know, it seems ridiculous, but I talked to a few other fairly savvy Rails users and they had no idea either. I'm beginning to think my misunderstanding is fairly common.

To make the feature less confusing and its intent clearer I've renamed "transactional fixtures" to "transactional tests". I deprecated the old usage and made it backwards-compatible so either will work but the new one will be preferred.

Let me know what you think!

Closes rails/rails#18864: Renaming transactional fixtures to transact…
…ional tests

I’m renaming all instances of `use_transcational_fixtures` to
`use_transactional_tests` and “transactional fixtures” to
“transactional tests”.

I’m deprecating `use_transactional_fixtures=`. So anyone who is
explicitly setting this will get a warning telling them to use
`use_transactional_tests=` instead.

I’m maintaining backwards compatibility—both forms will work.
`use_transactional_tests` will check to see if
`use_transactional_fixtures` is set and use that, otherwise it will use
itself. But because `use_transactional_tests` is a class attribute
(created with `class_attribute`) this requires a little bit of hoop
jumping. The writer method that `class_attribute` generates defines a
new reader method that return the value being set. Which means we can’t
set the default of `true` using `use_transactional_tests=` as was done
previously because that won’t take into account anyone using
`use_transactional_fixtures`. Instead I defined the reader method
manually and it checks `use_transactional_fixtures`. If it was set then
it should be used, otherwise it should return the default, which is
`true`. If someone uses `use_transactional_tests=` then it will
overwrite the backwards-compatible method with whatever they set.

Removing deprecation of `use_transactional_fixtures`
It was introduced in #19282 and has existed for one major version.
It looks like other deprecations from 5.0 are being removed so I
think it’s time to remove this.

Corrects transactional fixture check for Rails 5
In Rails 5 `ActiveSupport::TestCase` now uses `use_transactional_tests`
rather than `use_transactional_fixtures` as its method to check whether
transactional fixtures are being utilized for the current test.

See: rails/rails#19282
