Spectator

Test driven development red-green cycle for simple people!

The gist

Spectator is a simple watcher for your specs:

it will execute a spec each time a file (spec or implementation) is modified or created (really catches new files!)
it does not starts your whole suite at start, nor when a spec passes or fails (as autospec tends to do)
if you ask it runs the whole spec suite

Started as a custom Watchr script Spectator has grown up to a tiny gem!

Compatibility

Works with RSpec-1 and RSpec-2 (looks for a .rspec file in the project root).

Usage

Launch spectator in a terminal and go back to code!

The normal behavior is similar to autotest --fast-start --no-full-after-failed but gives the user a bit more control over execution. By hitting CTRL+C (or CMD+. on OSX) you get the following prompt:

^C (Interrupted with CTRL+C)
--- What to do now? (q=quit, a=all-specs):

Type q and ENTER (or CTRL+C again) to quit.

Type a and ENTER (or CTRL+C again) to execute the whole suite of specs.

Advanced Configuration

If you want to override some path matching:

BASE_DIR_REGEXP:

The glob that expanded will list the directories that contains the code. Default:

SPEC_DIR_REGEXP:

The glob that expanded will list the directories that contains the specs. Default:

RSPEC_COMMAND:

The full command that will run your specs. Default: bundle exec rspec (or bundle exec spec for RSpec 1.x)

Examples

Inline ENV variables

# this will match lib/opal/parser.rb to spec/cli/parser.rb
BASE_DIR_REGEXP='lib/opal' SPEC_DIR_REGEXP='spec/cli' spectator

Exported ENV variables

BASE_DIR_REGEXP: '(?:opal/corelib|stdlib|spec)'
SPEC_DIR_REGEXP: '(?:spec/corelib/core|spec/stdlib/\w+/spec)'
RSPEC_COMMAND: 'bundle exec ./bin/opal-mspec'

With a `.spectator.rb` script file

This file can be present in each project folder or in your home directory if you want to share general settings. When files are present in both folders the one in the home directory will be loaded first.

# contents of ".spectator.rb" file

ENV['BASE_DIR_REGEXP']  = '(?:opal/corelib|stdlib|spec)'
ENV['SPEC_DIR_REGEXP:'] = '(?:spec/corelib/core|spec/stdlib/\w+/spec)'
ENV['RSPEC_COMMAND']    = 'bundle exec ./bin/opal-mspec'

require 'spectator/success_notifier'

module Spectator
  class SuccessNotifier
    def notify(success)
      fork { exec "say #{say_message(success)}" }
      super
    end

    def say_message(success)
      success ? 'All right' : 'Ouch'
    end
  end
end
