rails c ⇒ odd, empty test runs.

[rking]

If you start with rails new foo && cd foo

Then edit the Gemfile to have:

group :development do
  gem 'turn'
  gem 'pry-rails'
end

Then run: rails c

Then hit ^D to exit the console, you'll get funky output like this:

Loaded Suite test,test/functional,test/unit,test/unit/helpers,test/performance
Started at 2012-12-03 05:56:45 +0000 w/ seed 23441.
Finished in 0.839736 seconds.
0 tests, 0 passed, 0 failures, 0 errors, 0 skips, 0 assertions

This doesn't happen:

• without the turn gem
• without the pry-rails gem (not even if you Pry.start from ~/.irbrc)

We haven't had time to look into it beyond seeing that:

• It comes from the test autorun stuff
• railties-3.2.9/lib/rails/console/app.rb has a funky hack:

# work around the at_exit hook in test/unit, which kills IRB
Test::Unit.run = true if Test::Unit.respond_to?(:run=)

Any clues about this one?

Bundler automatically require "<gem name>" by default: http://gembundler.com/v1.2/man/gemfile.5.html#REQUIRE-AS-require-.

Since you probably only want to load turn when you run tests, I'd suggest bundling turn like this:

gem "turn", :require => false

And explicitly put require "turn/autorun" in tests/test_helper.rb.

The latest version of Turn shouldn't have this problem. That's why turn/autorun become necessary --so Bundler could load turn without triggering a test run. I wonder what pry-rails has to do it with it too. That's seems especially odd.

This is still present, as described above, with the GitHub master branch version of Turn.

Solution from @5long fixed it for me, thanks!

Unfortunately the clash between Test::Unit and MiniTest has been a pain in the ass from day one. MiniTest should have never have usurped Test::Unit's namespace. That Bundler autoload's everything in the Gemfile only made matters worse.

I don't know why the railtie work around is being used. It seems like a mistake to me. Why would you run tests just b/c Test::Unit responds to #run=?
