RSpec::Cli

This is an extension to rspec to fascilitate cli testing.

Add this line to your application's Gemfile:

gem 'rspec-cli'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rspec-cli

In your rspec config

RSpec.configure do |config|
  config.include RSpec::Cli, type: :feature

  config.alias_example_group_to :feature, :type => :feature
  config.alias_example_to :scenario
end

or similar.

Now your feature specs will have helper methods new_cli_process(%w[echo hi there :D]) and spawn_cli_process(%w[echo hi there :D])

The first one returns a CliProcess instance that hasn't spawned your command yet.

The second one returns a CliProcess instance that has spawned your command.

The CliProcess instance has some useful methods like #read_all to read from it's stdout, #write(string) to write to it's stdin and #status to get the process's status.

As close to semantic versioning as I can be sure of (earlier in the project I broke semantic versioning, but everything past tag 0.2.0 is correct)

1. Fork it ( https://github.com/[my-github-username]/rspec-cli/fork )
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Add some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create a new Pull Request
