If you are a RailsCast Pro subscriber, I recommend to watch #261 Testing JavaScript with Jasmine (revised) for an introduction to Jasmine, Jasminerice and Guard::Jasmine.
The simplest way to install Guard is to use Bundler. Please make sure to have Guard installed.
Add Guard::Jasmine to your Gemfile
:
group :development, :test do
gem 'guard-jasmine'
end
Add the default Guard::Jasmine template to your Guardfile
by running:
$ guard init jasmine
Please have a look at the CHANGELOG when upgrading to a newer Guard::Jasmine version.
You need the PhantomJS browser installed on your system. You can download binaries for Mac OS X and Windows from the PhantomJS download section.
Alternatively you can install Homebrew on Mac OS X and install it with:
$ brew install phantomjs
If you are using Ubuntu 12.04 or above, phantomjs is in the official repositories and can be installed with apt:
$ sudo apt-get install phantomjs
For older versions of Ubuntu, you will need to add a repository first:
$ sudo add-apt-repository ppa:jerome-etienne/neoip
$ sudo apt-get update
$ sudo apt-get install phantomjs
You can also build it from source for several other operating systems, please consult the PhantomJS build instructions.
With Rails 3.1 and later you can write your Jasmine specs in addition to JavaScript with CoffeeScript, fully integrated into the Rails asset pipeline with Jasminerice. You have full access to your running Rails app, but it's a good practice to fake the server response. Check out the excellent Sinon.JS documentation to learn more about this topic.
Guard::Jasmine will start a Rails Rack server to run your specs.
- Guard is triggered by a file modification.
- Guard::Jasmine executes the PhantomJS script.
- The PhantomJS script requests the Jasmine test runner via HTTP.
- Rails uses the asset pipeline to get the Jasmine runner, the code to be tested and the specs.
- The asset pipeline prepares the assets, compiles the CoffeeScripts if necessary.
- The asset pipeline has finished to prepare the needed assets.
- Rails returns the Jasmine runner HTML.
- PhantomJS requests linked assets and runs the Jasmine tests headless.
- The PhantomJS script collects the Jasmine runner results and returns a JSON report.
- Guard::Jasmine reports the results to the console and system notifications.
Please read the detailed installation and configuration instructions at Jasminerice.
In short, you add it to your Gemfile
:
group :development, :test do
gem 'jasminerice'
end
And run following from the Terminal:
mkdir -p spec/javascripts
echo -e "#=require application\n#=require_tree ./" > spec/javascripts/spec.js.coffee
echo -e "/*\n *=require application\n */" > spec/javascripts/spec.css
This creates the directory spec/javascripts
where your CoffeeScript tests goes into. You define the Rails
asset pipeline manifest in spec/javascripts/spec.js.coffee
:
#=require application
#=require_tree ./
It also creates an empty spec/javascripts/spec.css
file as it is always requested when running specs.
Now you can access /jasmine
when you start your Rails server normally.
jasmine-rails is another option for integrating your Jasmine tests with an asset pipeline-enabled Rails application. The quick-and-dirty recipe for this is:
-
Add
jasmine-rails
to yourGemfile
:group :test do gem "jasmine-rails" end
-
Configure a mount point in your application's
routes.rb
(please refer to the jasmine-rails documentation for more details):mount JasmineRails::Engine => '/spec' if defined?(JasmineRails)
-
Configure Guard::Jasmine to reference the mount point in your
Guardfile
:guard 'jasmine', :server => :webrick, :server_mount => '/specs' do # watch stuff end
-
Profit! Seriously, you should be able to access the Jasmine runner at
/specs
within your Rails application, and Guard::Jasmine should run the same specs. Now no more excuses, get that javascript tested!
Jasmine Stories is a Jasminerice clone and that serves Jasmine-species acceptance tests.
In short, you add it to your Gemfile
:
group :development, :test do
gem 'jasmine-stories'
end
And run following from the Terminal:
mkdir -p spec/javascripts/stories
echo -e "#=require_tree ./stories" > spec/javascripts/stories.js.coffee
echo -e "/*\n *=require application\n */" > spec/javascripts/spec.css
This creates the directory spec/javascripts/stories
where your CoffeeScript acceptance tests goes into.
Now you can access /jasmine-stories
when you start your Rails server normally. You have to change the Jasmine runner
accordingly:
guard :jasmine, port: 8888, jasmine_url: 'http://127.0.0.1:8888/jasmine-stories' do
...
end
With Rails without the asset pipeline or a plain Ruby project, you can use the Jasmine Gem to configure your Jasmine specs and server the Jasmine runner. You don't have full access to your running Rails app, but it's anyway a good practice to fake the server response. Check out the excellent Sinon.JS documentation to learn more about this topic.
Guard::Jasmine will start a Jasmine Gem Rack server to run your specs.
- Guard is triggered by a file modification.
- Guard::Jasmine executes the PhantomJS script.
- The PhantomJS script requests the Jasmine test runner via HTTP.
- The Jasmine Gem reads your configuration and get the assets.
- The Jasmine Gem serves the the code to be tested and the specs.
- PhantomJS runs the Jasmine tests headless.
- The PhantomJS script collects the Jasmine runner results and returns a JSON report.
- Guard::Jasmine reports the results to the console and system notifications.
Please read the detailed installation and configuration instructions at the Jasmine Gem.
In short, you add the Jasmine gem to your Gemfile
:
group :development, :test do
gem 'jasmine'
end
and generate the configuration files.
Install the Jasmine gem in your Rails 3 app with:
$ rails g jasmine:install
Install the Jasmine gem in your Rails 2 app with:
$ script/generate jasmine
Now you can configure your spec suite in the Jasmine configuration file specs/javascripts/support/jasmine.yml
.
It is also possible to use CoffeeScript in this setup, by using Guard::CoffeeScript to compile your code and even specs. Just add something like this before Guard::Jasmine:
guard 'coffeescript', input: 'app/coffeescripts', output: 'public/javascripts'
guard 'coffeescript', input: 'spec/coffeescripts', output: 'spec/javascripts'
If you like to use Guard::Jasmine with a plain Ruby project, you can create a Rack configuration file that starts a Rails instance with the asset pipeline and Jasminerice, having the full Rails testing comfort for non-Rails projects. Please have a look at the Rails with the asset pipeline section to see how the setup works.
First you have the add the needed Gems to your Gemfile
:
group :assets do
gem 'coffee-script'
end
group :development, :test do
gem 'actionpack', '~> 3.2'
gem 'railties', '~> 3.2'
gem 'tzinfo'
gem 'thin'
gem 'jasminerice'
gem 'jquery-rails'
gem 'guard-jasmine'
end
We add support for CoffeeScript specs, using Thin as spec server and adding Jasminerice and jQuery
(which is needed by Jasminerice) to the Gems. After installing the gems with bundle
, we can
create a Rack configuration to spin up a mini-Rails app for testing:
require 'action_controller/railtie'
require 'jasminerice'
require 'guard/jasmine'
require 'sprockets/railtie'
require 'jquery-rails'
class JasmineTest < Rails::Application
routes.append do
mount Jasminerice::Engine: '/jasmine'
end
config.cache_classes = true
config.active_support.deprecation = :log
config.assets.enabled = true
config.assets.version = '1.0'
config.secret_token = '9696be98e32a5f213730cb7ed6161c79'
end
JasmineTest.initialize!
run JasmineTest
The mini Rails app is now ready to start and serve the Jasmine specs. You only have to create
spec/javascripts/spec.js.coffee
, the Jasminerice asset pipeline manifest, and configure the
assets:
#= require jquery
#= require_tree .
Start the test server manually with bundle exec rackup -p 3000
and visit http://localhost:3000/jasmine
to verify it works. If everything is fine, you can continue with adding Guard::Jasmine to your Guardfile
and have your non-Rails app comfortably tested in a headless environment.
Please read the Guard usage documentation.
Guard::Jasmine can be adapted to all kind of projects. Please read the Guard documentation for more information about the Guardfile DSL.
guard 'jasmine' do
watch(%r{spec/javascripts/spec\.(js\.coffee|js|coffee)$}) { "spec/javascripts" }
watch(%r{spec/javascripts/.+_spec\.(js\.coffee|js|coffee)$})
watch(%r{app/assets/javascripts/(.+?)\.(js\.coffee|js|coffee)$}) { |m| "spec/javascripts/#{m[1]}_spec.#{m[2]}" }
end
There are many options that can customize Guard::Jasmine to your needs. Options are simply supplied as hash when
defining the Guard in your Guardfile
:
guard 'jasmine', all_on_start: false, specdoc: :always do
...
end
The server options configures the server environment that is needed to run Guard::Jasmine:
server: :jasmine_gem # Jasmine server to use, either :auto, :none,
# :webrick, :mongrel, :thin, :unicorn, :jasmine_gem, :puma
# default: :auto
server_env: :test # Jasmine server Rails environment to set,
# e.g. :development or :test
# default: RAILS_ENV is exists, otherwise :development
server_timeout: 30 # The number of seconds to wait for the Jasmine spec server
# default: 15
port: 8888 # Jasmine server port to use.
# default: a random, free server port
phantomjs_bin: '~/bin/phantomjs' # Path to phantomjs.
# default: auto-detect 'phantomjs'
timeout: 20 # The time in seconds to wait for the spec runner to finish.
# default: 10
rackup_config: 'spec/dummy/config.ru' # Path to rackup config file (i.e. for webrick, mongrel, thin, unicorn, puma).
# default: ./config.ru
# This option is useful when using guard-jasmine in a mountable engine
# and the config.ru is within the dummy app
If you're setting the :server
option to :none
or need to access your specs on a other host than localhost
, you can
supply the Jasmine runner url manually:
jasmine_url: 'http://192.168.1.5:1234/jasmine' # URL where Jasmine is served.
# default: nil
You may want to have also a fixed port instead of the random generated one.
The reason why the Server environment is set to development
by default is that in development mode
the asset pipeline doesn't concatenate the JavaScripts and you'll see the line number in the real file,
instead of a ridiculous high line number in a single, very large JavaScript.
If you supply an unknown server name as the :server
option, then Guard::Jasmine will execute
a rake
task with the given server name as task in a child process. For example, if you configure
server: 'start_my_server'
, then the command rake start_my_server
will be executed and
you have to make sure the server starts on the port that you can get from the JASMINE_PORT
environment variable.
The spec runner options configures the behavior driven development (or BDD) cycle:
spec_dir: 'app/spec' # Directory with the Jasmine specs.
# default: 'spec/javascripts'
clean: false # Clean the spec list by only keep Jasmine specs within the project.
# default: true
all_on_start: false # Run all suites on start.
# default: true
keep_failed: false # Keep failed suites and add them to the next run again.
# default: true
all_after_pass: false # Run all suites after a suite has passed again
# after failing.
# default: true
The :keep_failed
failed option remembers failed suites and not failed specs. The reason for this decision is to
avoid additional round trip time to request the Jasmine test runner for each single spec, which is mostly more expensive
than running a whole suite.
In general you want to leave the :clean
flag on, which ensures that only Jasmine specs (files ending with _spec.js
,
_spec.coffee
and _spec.js.coffee
inside your project are passed to the runner. If you have a custom project
structure or spec naming convention, you can set :clean
to false to skip that file filter.
Guard::Jasmine can generate an RSpec like specdoc in the console after running the specs and you can set when it will be shown in the console:
specdoc: :always # Specdoc output options,
# either :always, :never or :failure
# default: :failure
focus: false # Specdoc focus to hide successful specs when
# at least one spec fails.
# default: true
console: :always # Console.log output options,
# either :always, :never or :failure
# default: :failure
errors: :always # Error output options,
# either :always, :never or :failure
# default: :failure
With the option set to :always
, the specdoc is shown with and without errors in your spec, whereas on with the option
set to :never
, there is no output at all, instead just a summary of the spec run is shown. The default option
:failure
shows the specdoc when at least one spec failed.
When :focus
is enabled, only the failing specs are shown in the specdoc when at least one spec is failing.
The :errors
option is partially working when using at least PhantomJS version 1.5. Please see
Issue #166 for the actual status of retreiving the JavaScript
stack trace.
You may want to have different options when the spec runner runs all specs. You can specify the :run_all
option
as a Hash that contains any valid runner option and will overwrite the general options.
run_all: { specdoc: :never } # Run all options,
# Takes any valid option
# default: {}
The :console
options adds captured console logs from the spec runner and adds them to the specdoc. Guard:Jasmine
contains its own minimalistic console implementation. The following console methods are supported:
console.log
console.info
console.warn
console.error
console.debug
The difference for each of this log methods is simply a prefix that is added to the log statement. The log also supports the common format placeholders:
%s
%i
,%d
%f
%o
You can further customize the log output by implement one of these methods:
toString()
- must return a string that describes the objecttoJSON()
- must return an object that is used instead of the actual object.
In addition, the console can log jQuery collections and outputs the HTML representation of the element by using the
jQuery html()
method.
Guard::Jasmine supports coverage reports generated by Istanbul. You need to
have istanbul
in your path in order to make this feature work. You can install it with NPM
$ npm install -g istanbul
You also need to explicit enable the coverage support in the options:
coverage: true # Enable/disable JavaScript coverage support
# default: false
Istanbul needs to instrument the implementation files so that the execution path can be detected. Guard::Jasmine comes
with a tilt template that generates instrumented implementation files when using in the asset pipeline. If you do not
use asset pipeline, than you need to instrument your files on your own, either manually (basic example: istanbul instrument --output instrumented_scripts scripts
) or by using something like
Guard::Process. You can get more information about the
instrumentation with istanbul help instrument
. You'll also need to update your :spec_dir
or jasmine.yml/src_dir
settings to point Guard::Jasmine to these instrumented source files.
Important: You need to clear the asset cache when you change this setting, so that already compiled assets will be recompiled. Just use the Sprockets supplied Rake task:
$ rake assets:clean
By default Guard::Jasmine just outputs the coverage when enable without any effect on the spec run result. You can make Guard::Jasmine fail the spec run when a given threshold is not met. You can set the following thresholds:
statements_threshold: 95 # Statements coverage threshold
# default: 0
functions_threshold: 85 # Functions coverage threshold
# default: 0
branches_threshold: -10 # Branches coverage threshold
# default: 0
lines_threshold: -15 # Lines coverage threshold
# default: 0
A positive threshold is taken to be the minimum percentage required, a negative threshold represents the maximum number of uncovered entities allowed.
Guard::Jasmine always shows the Istanbul text report after a spec run that contains the coverage results per file. You can also enable two more reports:
coverage_html: true # Enable Istanbul HTML coverage report
# default: false
coverage_html_dir: './coverage' # Directory to write Istanbul HTML coverage report to
# default: './coverage'
coverage_summary: true # Enable Istanbul summary coverage report
# default: false
The :coverage_summary
options disables the detailed file based coverage report by a small summary coverage report.
Both of these results are more useful if they are run against the coverage data from a full spec run, so it's strongly
advised to enable the :all_on_start
option.
With Jasmine in the asset pipeline all instrumented implementation files are available in the runtime and when you execute a partial spec run it reports a lower coverage for the excluded files, since their associated specs aren't run. Guard::Jasmine tries to work around this by merge only the coverage data for the changed files (Istanbul knows the file name in opposite to Jasmine).
You can use the Cobertura format to bring coverage support to Jenkins CI, even that Guard::Jasmine has no built in support for it. The trick is to post-process the coverage data with istanbul after the spec run:
desc "Run all JavaScript specs with Istanbul"
task :jscov => :environment do
# Run Jasmine tests with code coverage on and generate Jenkins-compatible Jasmine code coverage report file.
# Must run assets:clean first to force re-compilation.
# Make sure to fail this task if there are unit test failures.
# For some reason does not work if run as separate exec's, so combine into one.
exec('rake assets:clean; guard-jasmine --coverage --coverage-html --coverage-summary; \
code=$?; if [ $code != "0" ]; then exit $code; fi; istanbul report cobertura')
end
These options affects what system notifications 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
max_error_notify: 5 # Maximum error notifications to show.
# default: 3
Jasmine doesn't know anything about your test files, it only knows the name of your specs that you specify in the
describe
function. When a file change is detected, Guard::Jasmine extracts the first spec name of the file and uses
that spec description as spec filter.
So if you want to have a precise spec detection, you should:
- Use only one top-level description per spec file.
- Make each top-level description unique.
To get a feeling how your naming strategy works, play with the web based Jasmine runner and modify the spec
query
parameter.
Guard::Jasmine includes a little command line utility to run your specs once and output the specdoc to the console.
$ guard-jasmine
You can get help on the available options with the help

Run the Jasmine spec runner
By default all specs are run, but you can supply multiple paths to your specs to run only a subset:
$ guard-jasmine spec/javascripts/a_spec.js.coffee spec/javascripts/another_spec.js.coffee
Guard::Jasmine provides a Rake task wrapper around the Thor command line utility. Simply create a JasmineTask within
your Rakefile
:
require 'guard/jasmine/task'
Guard::JasmineTask.new
You can configure the CLI options either by providing the options as parameter or use a block:
require 'guard/jasmine/task'
Guard::JasmineTask.new do |task|
task.options = '-t 15 -e test'
end
Guard::JasmineTask.new(:jasmine_no_server, '-s none')
Now you'll set your tasks in the Rake task list:
$ rake -T guard
rake guard:jasmine # Run all Jasmine specs
rake guard:jasmine_no_server # Run all Jasmine specs
and you can execute the Guard::Jasmine specs on the console by running the task:
$ rake guard:jasmine
With the given guard-jasmine
script you're able to configure Travis CI to run Guard::Jasmine.
Simply use the script
setting in your .travis.yml
:
script: 'bundle exec guard-jasmine --server-timeout=60'
You can also run your Guard::Jasmine specs after your specs that are ran with rake
by using &&
:
script: 'rake spec && bundle exec guard-jasmine'
When using a PhantomJS version prior to 1.5, you need to start xvfb
before running the specs:
before_script:
- "export DISPLAY=:99.0"
- "sh -e /etc/init.d/xvfb start"
Tip: It's highly recommended the have a server timeout of at least 60 seconds, since the performance of the Travis VMs seems to vary quite a bit; sometimes the Jasmine server starts in 5 seconds, sometimes it takes as long as 50 seconds.
When building an engine, your code lives at the root but the dummy Rails app is in another folder (like test/dummy
or spec/dummy
).
So you have to import the Jasmine task in your Rakefile
:
$ echo "import 'lib/tasks/jasmine.rake'" > Rakefile
$ bundle exec rake -T jasmine
rake jasmine # Run specs via server
rake jasmine:ci # Run continuous integration tests
Given your configuration, you could also need to set:
-
jasmine_url
in yourGuardfile
as explained above -
the server url in the command line:
bundle exec guard-jasmine -u http://localhost:8888/
There are many ways to get your Jasmine specs run within a headless environment. If Guard::Jasmine isn't for you, I recommend to check out these other brilliant Jasmine runners:
- guard-konacha, Automatically run konacha tests through Guard.
- guard-teabag, Guard-Teabag: Run Javascript tests with Guard and all the features of Teabag
- Karma spectacular Test Runner for JavaScript.

This Guard comes with a small executable guard-jasmine-debug
that can be used to run the Jasmine test runner on PhantomJS
and see the JSON result that gets evaluated by Guard::Jasmine. This comes handy when there is an issue with your specs
and you want to see the output of the PhantomJS script.
$ guard-jasmine-debug
The only argument that the script takes is the URL to the Jasmine runner, which defaults to
http://127.0.0.1:3000/jasmine
. So you can for example just run a subset of the specs by changing the URL:
$ guard-jasmine-debug http://127.0.0.1:3000/Jasmine?spec=YourSpec
