Feature: Reek can be driven through its Task
  Reek provides an easy way to integrate its use into Rakefiles,
  via the Task class. These scenarios test its various options.

  Scenario: source_files points at the desired files
    When I run rake reek with:
      """
      Reek::Rake::Task.new do |t|
        t.source_files = 'spec/samples/standard_smelly/minimal_dirty.rb'
        t.reek_opts = '--no-color'
      end
      """
    Then the exit status indicates an error
    And it reports:
      """
      spec/samples/standard_smelly/minimal_dirty.rb -- 3 warnings:
        [1]:C has no descriptive comment (IrresponsibleModule)
        [1]:C has the name 'C' (UncommunicativeModuleName)
        [2]:C#m has the name 'm' (UncommunicativeMethodName)
      """

  Scenario: name changes the task name
    When I run rake silky with:
      """
      Reek::Rake::Task.new('silky') do |t|
        t.source_files = 'spec/samples/standard_smelly/minimal_dirty.rb'
        t.reek_opts = '--no-color'
      end
      """
    Then the exit status indicates an error
    And it reports:
      """
      spec/samples/standard_smelly/minimal_dirty.rb -- 3 warnings:
        [1]:C has no descriptive comment (IrresponsibleModule)
        [1]:C has the name 'C' (UncommunicativeModuleName)
        [2]:C#m has the name 'm' (UncommunicativeMethodName)
      """

  Scenario: verbose prints the reek command
    When I run rake reek with:
      """
      Reek::Rake::Task.new do |t|
        t.source_files = 'spec/samples/masked/dirty.rb'
        t.verbose = true
      end
      """
    Then the exit status indicates an error
    And stdout includes "spec/samples/masked/dirty.rb"

  Scenario: fail_on_error can hide the error status
    When I run rake reek with:
      """
      Reek::Rake::Task.new do |t|
        t.fail_on_error = false
        t.source_files = 'spec/samples/no_config_file/dirty.rb'
        t.reek_opts = '--no-color'
      end
      """
    Then it reports no errors
    And it succeeds
    And it reports:
      """
      spec/samples/no_config_file/dirty.rb -- 6 warnings:
        [5]:Dirty has the variable name '@s' (UncommunicativeVariableName)

  Scenario: can be configured with config_files
