cmd_line_test - Extends Shoulda or Test::Unit with macros for testing command line apps
Basic Usage
Installation
$ gem install cmd_line_test
Example
If you are about to start writing new command line utility MyCommandLineApp, you probably want to specify its options and behavior, likely in form of tests. This gem is aimed to simplify creation of such tests:
requrie 'cmd_line_test'
class CliTest < Test::Unit::TestCase
run_command_line_as {MyCommandLineApp.run}
run_with_argv "--help" do
assert_successful_run
assert_out_contains /Usage:/
end
end
Shortcomings
Only tested on the 1.8.7 Ruby implementation and with Shoulda 2.10.1
