Prepare for separation of RSpec helper files Since rspec-rails 3, the default installation creates two helper files: * `spec_helper.rb` * `rails_helper.rb` `spec_helper.rb` is intended as a way of running specs that do not require Rails, whereas `rails_helper.rb` loads Rails (as Discourse's current `spec_helper.rb` does). For more information: https://www.relishapp.com/rspec/rspec-rails/docs/upgrade#default-helper-files In this commit, I've simply replaced all instances of `spec_helper` with `rails_helper`, and renamed the original `spec_helper.rb`. This brings the Discourse project closer to the standard usage of RSpec in a Rails app. At present, every spec relies on loading Rails, but there are likely many that don't need to. In a future pull request, I hope to introduce a separate, minimal `spec_helper.rb` which can be used in tests which don't rely on Rails. 2015-10-11 17:41:23 +08:00			`require 'rails_helper'`

Convert specs to RSpec 2.99.2 syntax with Transpec This conversion is done by Transpec 3.1.0 with the following command: transpec * 424 conversions from: obj.should to: expect(obj).to * 325 conversions from: == expected to: eq(expected) * 38 conversions from: obj.should_not to: expect(obj).not_to * 15 conversions from: =~ /pattern/ to: match(/pattern/) * 9 conversions from: it { should ... } to: it { is_expected.to ... } * 5 conversions from: lambda { }.should_not to: expect { }.not_to * 4 conversions from: lambda { }.should to: expect { }.to * 2 conversions from: -> { }.should to: expect { }.to * 2 conversions from: -> { }.should_not to: expect { }.not_to * 1 conversion from: === expected to: be === expected * 1 conversion from: =~ [1, 2] to: match_array([1, 2]) For more details: https://github.com/yujinakayama/transpec#supported-conversions 2015-04-25 23:18:35 +08:00			`expect(Dir.entries(File.dirname(path)).length).to eq(3)`
