Modify helper methods provided by ControllerBuilder so that we use as
much of rspec-rails's controller example group capabilities as possible.
All of this can still be improved but this is a good start for now.
Currently before running unit tests we are getting auto-required before
rspec-rails is getting required. This is bad because we need to wait
until rspec-rails is loaded before injecting Shoulda::Matchers::* into
the current RSpec context, otherwise matchers that clash with
rspec-rails (such as `render_template` will get overridden).
This is happening when creating and booting the Rails application.
Bundler will auto-require any gems in the Gemfile. One of these gems is
ourselves (via the `gemspec` line). Since there aren't any dependencies
in the gemspec, there's no need for us to be in the Gemfile.
This means that we no longer have to explicit `include` Rails
ActionController template assertions in the tests for `render_template`
as they should get included automatically for us.
When running unit tests we need to ensure that we are simulating how
other people will use the matchers as best we can. This means, for
instance, tagging any example groups that test controller matchers as
controller example groups.
* Change 'spec' Rake task to 'spec:unit'
* Require unit_spec_helper.rb in unit tests, not spec_helper.rb
* Re-namespace files in spec/support/unit under UnitTests
* Files in spec/support/unit/helpers no longer automatically add
themselves to RSpec - this happens in unit_spec_helper.rb
* Extract RecordWithDifferentErrorAttributeBuilder and
RecordValidatingConfirmationBuilder to separate files
* Move spec/shoulda to spec/unit_tests/shoulda
* Move spec/support/*.rb to spec/support/unit_tests/{helpers,matchers}
* Move spec_helper.rb to unit_spec_helper.rb
