The Jasmine Gem

The Jasmine Ruby Gem is a package of helper code for developing Jasmine projects for Ruby-based web projects (Rails, Sinatra, etc.) or for JavaScript projects where Ruby is a welcome partner. It serves up a project's Jasmine suite in a browser so you can focus on your code instead of manually editing script tags in the Jasmine runner HTML file.

Contents

This gem contains:

  • A small server that builds and executes a Jasmine suite for a project
  • A script that sets up a project to use the Jasmine gem's server
  • Generators for Ruby on Rails projects (Rails 3 and Rails 4)

You can get all of this by: gem install jasmine or by adding Jasmine to your Gemfile.

group :development, :test do
  gem 'jasmine'
end

Init A Project

To initialize a project for Jasmine

rails g jasmine:install rails g jasmine:examples

For any other project (Sinatra, Merb, or something we don't yet know about) use

jasmine init

Usage

Start the Jasmine server:

rake jasmine

Point your browser to localhost:8888. The suite will run every time this page is re-loaded.

For Continuous Integration environments, add this task to the project build steps:

rake jasmine:ci

This uses PhantomJS to load and run the Jasmine suite.

Configuration

Customize spec/javascripts/support/jasmine.yml to enumerate the source files, stylesheets, and spec files you would like the Jasmine runner to include. You may use dir glob strings.

Alternatively, you may specify the path to your jasmine.yml by setting an environment variable:

rake jasmine:ci JASMINE_CONFIG_PATH=relative/path/to/your/jasmine.yml

In addition, the spec_helper key in your jasmine.yml specifies the path to a ruby file that can do programmatic configuration. After running jasmine init or rails g jasmine:install it will point to spec/javascripts/support/jasmine_helper.rb which you can modify to fit your needs.

Running Jasmine on a different port

The ports that rake jasmine (or rake jasmine:server) and rake jasmine:ci run on are configured independently, so they can both run at the same time.

To change the port that rake jasmine uses:

In your jasmine_helper.rb:

Jasmine.configure do |config|
   config.server_port = 5555
end

By default rake jasmine:ci will attempt to find a random open port, to set the port that rake jasmine:ci uses:

In your jasmine_helper.rb:

Jasmine.configure do |config|
   config.ci_port = 1234
end
