Do people run tests with `ruby -Ilib:test`?

[andrewculver]

Had someone reach out because running tests with the following invocation doesn't work:

ruby -Ilib:test test/models/user_test.rb

Is that a normal way to invoke tests? I've always used rails test ... or rake test TEST=....

[esmale]

I also just run rails test

I just tried the ruby -Ilib:test method of invocation and this is the error, just for reference:

$ ruby -I"lib:test" test/models/user_test.rb

I really don't think that's a valid way to run a single test if you're inside of a rails application. It seems to skip some of the Rails Magic around loading of gems, or something.

I think we can close this one.

Just here to confirm that I got the same error.

If it's an eager loading issue, that's been one of the big problems we've encountered with tests across the whole bt architecture. Also in favor of closing this one.
