This is an effort to vastly decrease the time it takes to run a single
unit test file and therefore increase productivity and happiness for
people working on this project.
If you want to run a unit test file, now you can use `zeus rspec`
instead of `rspec` -- assuming you run `zeus start` first -- and it will
run a LOT faster.
Because test files tend to have long file paths, you can even use a
shorter version of those paths. So instead of saying:
zeus rspec spec/unit/shoulda/matchers/active_record/validate_uniqueness_of_matcher_spec.rb
you can say:
zeus rspec active_record/validate_uniqueness_of_matcher_spec.rb
* Add missing steps to CONTRIBUTING and reorganize it a bit.
* `bundle exec rake` no longer runs all tests in all appraisals, only
the tests in the latest appraisal.
* Add a `.ruby-version` file so people don't have to figure out which
version of Ruby to install.
[ci skip]
If you attempt to run tests without specifying an Appraisal, then you
will be going off of the main Gemfile. The Gemfile is not guaranteed to
contain all of the dependencies necessary to run tests, so it is very
likely that you'll get an obscure error somewhere. Instead of letting
this happen, raise a specific error.
