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