Guard::RSpec

RSpec guard allows to automatically & intelligently launch specs when files are modified.

• Compatible with RSpec 1.x & RSpec 2.x (>= 2.4 needed for the notification feature).
• Tested against Ruby 1.8.7, 1.9.2, 1.9.3, REE and the latest versions of JRuby & Rubinius.

Install

Please be sure to have Guard installed before continue.

Install the gem:

$ gem install guard-rspec

Add it to your Gemfile (inside development group):

group :development do
  gem 'guard-rspec'
end

Add guard definition to your Guardfile by running this command:

$ guard init rspec

Usage

Please read Guard usage doc

Guardfile

RSpec guard can be really adapted to all kind of projects.

Standard RubyGem project

guard 'rspec' do
  watch(%r{^spec/.+_spec\.rb$})
  watch(%r{^lib/(.+)\.rb$})     { |m| "spec/lib/#{m[1]}_spec.rb" }
  watch('spec/spec_helper.rb')  { "spec" }
end

Typical Rails app

guard 'rspec' do
  watch('spec/spec_helper.rb')                        { "spec" }
  watch('config/routes.rb')                           { "spec/routing" }
  watch('app/controllers/application_controller.rb')  { "spec/controllers" }
  watch(%r{^spec/.+_spec\.rb$})
  watch(%r{^app/(.+)\.rb$})                           { |m| "spec/#{m[1]}_spec.rb" }
  watch(%r{^app/(.*)(\.erb|\.haml)$})                 { |m| "spec/#{m[1]}#{m[2]}_spec.rb" }
  watch(%r{^lib/(.+)\.rb$})                           { |m| "spec/lib/#{m[1]}_spec.rb" }
  watch(%r{^app/controllers/(.+)_(controller)\.rb$})  { |m| ["spec/routing/#{m[1]}_routing_spec.rb", "spec/#{m[2]}s/#{m[1]}_#{m[2]}_spec.rb", "spec/acceptance/#{m[1]}_spec.rb"] }
end

Please read Guard doc for more information about the Guardfile DSL.

Options

By default, Guard::RSpec automatically detect your RSpec version (with the spec_helper.rb syntax or with Bundler) but you can force the version with the :version option:

guard 'rspec', :version => 2 do
  # ...
end

You can pass any of the standard RSpec CLI options using the :cli option:

guard 'rspec', :cli => "--color --format nested --fail-fast --drb" do
  # ...
end

By default, Guard::RSpec will only look for spec files within spec in your project root. You can configure Guard::RSpec to look in additional paths by using the :spec_paths option:

guard 'rspec', :spec_paths => ["spec", "vendor/engines/reset/spec"] do
  # ...
end

If you have only one path to look, you can configure :spec_paths option with a string:

guard 'rspec', :spec_paths => "test" do
  # ...
end

Former :color, :drb, :fail_fast and :formatter options are deprecated and have no effect anymore.

List of available options:

:version => 1                # force use RSpec version 1, default: 2
:cli => "-c -f doc"          # pass arbitrary RSpec CLI arguments, default: "-f progress"
:bundler => false            # don't use "bundle exec" to run the RSpec command, default: true
:binstubs => true            # use "bin/rspec" to run the RSpec command (implies :bundler => true), default: false
:rvm => ['1.8.7', '1.9.2']   # directly run your specs on multiple Rubies, default: nil
:notification => false       # display Growl (or Libnotify) notification after the specs are done running, default: true
:all_after_pass => false     # run all specs after changed specs pass, default: true
:all_on_start => false       # run all the specs at startup, default: true
:keep_failed => false        # keep failed specs until they pass, default: true
:run_all => { :cli => "-p" } # cli arguments to use when running all specs, default: same as :cli
:spec_paths => ["spec"]      # specify an array of paths that contain spec files

DRb mode

When you specify --drb within :cli, guard-rspec will circumvent the rspec command line tool by directly communicating with the RSpec DRb server. This avoids the extra overhead incurred by your shell, bundler and loading RSpec's environment just to send a DRb message. It shaves off a second or two before the specs start to run; they should run almost immediately.

Notification

The notification feature is only available for RSpec < 2, and RSpec >= 2.4 (due to the multiple-formatters feature that was present in RSpec 1, was removed in RSpec 2 and reintroduced in RSpec 2.4). So if you are using a version between 2 and 2.4, you should disable the notification with :notification => false. Otherwise, nothing will be displayed in the terminal when your specs will run.

The best solution is still to update RSpec to the latest version!

Formatters

The :formatter option has been removed since CLI arguments can be passed through the :cli option. If you want to use the former Instafail formatter, you need to use rspec-instafail gem instead:

# in your Gemfile
gem 'rspec-instafail'

# in your Guardfile
guard 'rspec', :cli => '-r rspec/instafail -f RSpec::Instafail' do
  # ...
end

Default formatter is the progress formatter (same as RSpec default).

Running a subset of all specs

The :all_on_start and :all_after_pass options cause all specs located in the spec directory to be run. If there are some specs you want to skip, you can tag them with RSpec metadata (such as :slow => true) and skip them with the cli --tag option (i.e. --tag ~slow).

You can also use option :spec_paths to override paths used when running all specs. You can use this feature to create multiple groups of guarded specs with distinct paths, and execute each in own process:

# in your Guardfile
group 'acceptance-tests' do
  guard 'rspec', :spec_paths => ['spec/acceptance'] do
    # ...
  end
end

group 'unit-tests' do
  guard 'rspec', :spec_paths => ['spec/models', 'spec/controllers', 'spec/routing'] do
    # ...
  end
end
