Guard::RSpectacle Build Status

Guard::RSpectacle automatically tests your application with RSpec when files are modified.

Tested on MRI Ruby 1.8.7, 1.9.2, 1.9.3, REE and the latest versions of JRuby & Rubinius.

If you have any questions please join us on our Google group or on #guard (irc.freenode.net).

How it works

The idea is that Guard starts the Rails environment, reloads changed Ruby files and starts the RSpec runner embedded in the current process. Please be sure to understand the limitation of this approach.

If you want to use a safer approach to run your specs, try guard-rspec.

Install

Guard and Guard::RSpectacle

Please be sure to have Guard installed.

Add it to your Gemfile:

group :development
  gem 'guard-rspectacle'
end

and install it by running Bundler:

$ bundle

Add the guard definition to your Guardfile by running this command:

$ guard init rspectacle

Usage

Please read the Guard usage documentation for information about Guard.

Guardfile

Guard::RSpectacle can be adapted to all kind of projects. Please read the Guard documentation for more information about the Guardfile DSL.

guard :rspectacle do
  watch('spec/spec_helper.rb')                        { %w(spec/spec_helper spec) }
  watch('config/routes.rb')                           { %w(config/routes.rb spec/routing) }
  watch('app/controllers/application_controller.rb')  { 'spec/controllers' }

  watch(%r{^spec/.+_spec\.rb$})

  watch(%r{^app/(.+)\.rb$})                           { |m| ["app/#{m[1]}.rb", "spec/#{m[1]}_spec.rb"] }
  watch(%r{^lib/(.+)\.rb$})                           { |m| ["lib/#{m[1]}.rb", "spec/lib/#{m[1]}_spec.rb"] }
  watch(%r{^app/controllers/(.+)_controller\.rb$})    { |m| [
    "app/controllers/#{m[1]}_controller.rb",
    "spec/controllers/#{m[1]}_spec.rb",
    "spec/routing/#{m[1]}_routing_spec.rb",
    "spec/acceptance/#{m[1]}_spec.rb"
  ]}
end

NOTE: When using watch with a block, you must return all files that should be reloaded.

Options

There are many options that can customize Guard::RSpectacle to your needs. Options are simply supplied as hash when defining the Guard in your Guardfile:

guard :rspectacle, :cli => '--format Fuubar --backtrace --tag @focus', :all_on_start => false do
  ...
end

General options

The general options configures the environment that is needed to run Guard::RSpectacle and RSpec:

:cli => '--tag @focus'         # RSpec CLI options
                               # default: ''

Spork is not needed (and supported), thus the --drb flag will be removed from the :cli options.

Spec runner options

The spec runner options configures the behavior driven development (or BDD) cycle:

:all_on_start => false         # Run all specs on start.
                               # default: true

:keep_failed => false          # Keep failed examples and add them to the next run again.
                               # default: true

:all_after_pass => false       # Run all specs after all examples have passed again after failing.
                               # default: true

System notifications options

These options affects what system notifications (growl, libnotify or notifu) are shown after a spec run:

:notifications => false        # Show success and error notifications.
                               # default: true

:hide_success => true          # Disable successful spec run notification.
                               # default: false

Important note on reloading

The ability to run specs immediately comes at a cost:

  1. In your Guardfile, you have to specify which files should be reloaded (apart from specs to be executed). But don't worry, the default template takes care of it.
  2. When a file is changed, it is reloaded the Ruby code with Kernel#load, which only re-interprets the file.

This, for example, means that a method already defined on a class (including initialize) will not be removed simply by deleting that method from the source code:

class Dinner
  def initialize
    raise "Too early"
  end
end

The spec that uses this class will fail for the obvious reason. So your first thought may be to just remove initialize method. But that will not work and you should rewrite the class above:

class Dinner
  def initialize
    super
  end
end

When you are done testing, restart guard to load the file afresh. Unfortunately this inconvenience can't be fixed easily (suggest if you know how?). So just keep in mind: you are monkey-patching within a single guard session.

Alternatives

Please have a look at the rock solid guard-rspec. Guard::RSpectacle uses it for continuous testing.
