= CliCase - Macros for testing Ruby command line apps with Shoulda or Test::Unit

When you start thinking about writing ruby command line utility you likely want to start with writing test. Assuming command line parsing is in CliApp#run you prabably want to write something like:

  class CliTest < Test::Unit::TestCase
    run_command_line_as {CliApp.run}
  
    run_with_options ["--help"] do
      assert_successful_run
      assert_out_contains /Usage:/
    end
  end


Work in progress...
