Kasper Timm Hansen 0d72489b2a * Don't eagerly require Rails' minitest plugin.
By making the Rails minitest behave like a standard minitest plugin
we're much more likely to not break when people use other minitest
plugins. Like minitest-focus and pride.

To do this, we need to behave like minitest: require files up front
and then perform the plugin behavior via the at_exit hook.
This also saves us a fair bit of wrangling with test file loading.

Finally, since the environment and warnings options have to be applied
as early as possible, and since minitest loads plugins at_exit, they
have to be moved to the test command.

* Don't expect the root method.

It's likely this worked because we eagerly loaded the Rails minitest plugin
and that somehow defined a root method on `Rails`.

* Assign a backtrace to failed exceptions.

Otherwise Minitest pukes when attempting to filter the backtrace (which
Rails' backtrace cleaner then removes).

Means the exception message test has to be revised too.

This is likely caused by the rails minitest plugin now being loaded for
these tests and assigning a default backtrace cleaner.

Rails dev tools

This is a collection of utilities used for Rails internal development. They aren't used by Rails apps directly.

  • console drops you in irb and loads local Rails repos
  • profile profiles Kernel#require to help reduce startup time
  • line_statistics provides CodeTools module and LineStatistics class to count lines
  • test is loaded by every major component of Rails to simplify testing, for example: cd ./actioncable; bin/test ./path/to/actioncable_test_with_line_number.rb:5
