Feature: exclusion filters

  You can exclude examples from a run by declaring an exclusion filter and
  then tagging examples, or entire groups, with that filter.
  
  Scenario: exclude an example
    Given a file named "spec/sample_spec.rb" with:
      """
      RSpec.configure do |c|
        # declare an exclusion filter
        c.filter_run_excluding :broken => true
      end

      describe "something" do
        it "does one thing" do
        end

        # tag example for exclusion by adding metadata
        it "does another thing", :broken => true do
        end
      end
      """
    When I run "rspec ./spec/sample_spec.rb --format doc"
    Then the output should contain "does one thing"
    And the output should not contain "does another thing"

  Scenario: exclude a group
    Given a file named "spec/sample_spec.rb" with:
      """
