Bring in M to run tests

[qrush]

Run the entire test suite:

test

Run a directory of tests:

test "unit"

Run an entire test:

test "unit/upload"

Run a specific test:

irb(main):002:0> test "unit/upload:123"
No tests found on line 123. Valid tests to run:
  test_create: m test/unit/upload_test.rb:4
...
=> true

Some problems with this:

• You need to have the rails console in test environment to use this.
• I killed the print_test_usage help for now.
• This only works with 1.9+, MiniTest, or Test/Unit right now.
• Forking to run tests and canceling them causes MySQL to barf: ActiveRecord::StatementInvalid: Mysql2::Error: MySQL server has gone away mysql_errno=2006 sqlstate=HY000: SELECT @@FOREIGN_KEY_CHECKS
• MiniTest spits this out for me on killing the console, not sure why yet or if this is normal:
