Aaron Patterson da225c0db6 Fix Rails environment when running tests with Ruby ... I frequently run tests with `ruby`, not with a runner like `rake` or `rails`. When running the test with just `ruby` the `RAILS_ENV` environment variable did not get set to "test", and this would cause the tests to fail (and even mutate the development database!) This commit adds integration tests for running tests with just `ruby` and ensures the environment gets defaulted to "test". I also added a test to ensure that passing an environment to `-e` actually works (and fixed that case too). An interesting / annoying thing is that Minitest picks up it's plugins by asking RubyGems for a list of files: ca6a71ca90/lib/minitest.rb (L92-L100) This means that RubyGems needs to somehow know about the file before it can return it to Minitest. Since we are not packaging Rails as a Gem before running the integration tests on it (duh, why would you do that?), RubyGems doesn't know about the file, so it can't tell Minitest, so Minitest doesn't automatically require it. This means I had to manually require and insert the plugin in our integration test. I've left comments about that in the test as well. Ugh.		2017-12-06 20:40:04 -08:00
