Feature: Reek can be controlled using command-line options
  In order to change Reek's default behaviour
  As a developer
  I want to supply options on the command line

  Scenario: return non-zero status on bad option
    When I run reek --no-such-option
    Then the exit status indicates an error
    And it reports the error "Error: invalid option: --no-such-option"
    And there is no output on stdout

  Scenario: display the current version number
    When I run reek --version
    Then it succeeds
    And it reports the current version

  Scenario: return given status code when using --failure-exit-code
    Given the smelly file 'smelly.rb'
    When I run reek smelly.rb --failure-exit-code 23
    Then the exit status is 23

  Scenario: return given status code when using --success-exit-code
    Given the clean file 'clean.rb'
    When I run reek clean.rb --success-exit-code 42
    Then the exit status is 42

  Scenario: display the help information
    When I run reek --help
    Then it succeeds
    And it reports:
