Use Guard with jasmine-headless-webkit

README.md

Guard support for jasmine-headless-webkit

Add running your Jasmine specs to your Guardfile via jasmine-headless-webkit. Nice!

guard 'jasmine-headless-webkit' do
  watch(%r{^app/assets/javascripts/(.*)\..*}) { |m| newest_js_file("spec/javascripts/#{m[1]}_spec") }
end

gem install guard-jasmine-headless-webkit and then guard init jasmine-headless-webkit in your project directory to get started. You should also put it in your Gemfile because, hey, why not, right?

Output is colored by default. If you want it not colored, place a --no-colors option into the project's or your home folder's .jasmine-headless-webkit file.

guard options

  • :all_on_start => false to not run everything when starting, just like guard-rspec.
  • :valid_extensions => %w{js coffee} to only trigger run_on_change events for files with these extensions. Forces Guard to re-run all tests when any other matched file changes.
  • All other options from Jasmine::Headless::Runner: (see the list of available options)

Using with .erb files in the Rails 3.1 Asset Pipeline and/or Jammit

If your code required Jammit or ERB templates, which aren't directly supported by jasmine-headledd-webkit, use guard-rails-assets chained in before guard-jasmine-headless-webkit to precompile your application code for testing:

guard 'rails-assets' do
  watch(%r{^app/assets/javascripts/.*})
end

guard 'jasmine-headless-webkit' do
  watch(%r{^public/assets/.*\.js})
  ... specs ...
end

Do the same for Jammit, using guard-jammit.

guard-jammit and Jammit >= 0.6.0

Jammit >= 0.6.0 changed how it determines the Rails environment. Use my fork of guard-jammit until it's fixed upstream.

What's the deal with newest_js_file?

Since one could, theoretically, have a CoffeeScript app file and a JavaScript spec file (or vice versa), the search for the correct matching file is a little more complicated. newest_js_file extends the Guard DSL to search the given path for the newest .js or .coffee file:

newest_js_file('spec/javascripts/models/my_model')
  #=> search for Dir['spec/javascripts/models/my_model*.{js,coffee}'] and return the newest file found

If you 100% know you won't need that support, modify your Guardfile as appropriate.
