# Guard::Jasmine [![Build Status](https://secure.travis-ci.org/netzpirat/guard-jasmine.png)](http://travis-ci.org/netzpirat/guard-jasmine)

Guard::Jasmine automatically tests your Jasmine specs 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](http://groups.google.com/group/guard-dev) or on `#guard`
(irc.freenode.net).

## Highlights

* Continuous testing based on file modifications by [Guard][], manifold configuration by writing rules with RegExp and
Ruby.

* Fast headless testing on [PhantomJS][], a full featured WebKit browser with native support for
various web standards: DOM handling, CSS selector, JSON, Canvas, and SVG.

* Runs the standard Jasmine test runner, so you can use [Jasminerice][] for integrating [Jasmine][] into the
[Rails 3.1 asset pipeline][] and write your specs in [CoffeeScript][].

* Command line helper for CI server integration.

* Runs on Mac OS X, Linux and Windows.

## How it works

![Guard Jasmine](https://github.com/netzpirat/guard-jasmine/raw/master/resources/guard-jasmine.png)

1. Guard is triggered by a file modification.
2. Guard::Jasmine executes the [PhantomJS script][].
3. The PhantomJS script requests the Jasmine test runner via HTTP.
4. Rails uses the asset pipeline to get the Jasmine runner, the code to be tested and the specs.
5. The asset pipeline prepares the assets, compiles the CoffeeScripts if necessary.
6. The asset pipeline has finished to prepare the needed assets.
7. Rails returns the Jasmine runner HTML.
8. PhantomJS requests linked assets and runs the Jasmine tests headless.
9. The PhantomJS script extracts the result from the DOM and returns a JSON report.
10. Guard::Jasmine reports the results to the console and system notifications.

## Install

### Guard and Guard::Jasmine

The simplest way to install Guard is to use [Bundler](http://gembundler.com/).
Please make sure to have [Guard][] installed.

Add Guard::Jasmine to your `Gemfile`:

```ruby
group :development do
  gem 'guard-jasmine'
end
```

Add the default Guard::Jasmine template to your `Guardfile` by running:

```bash
$ guard init jasmine
```

### Jasminerice

With Rails 3.1 you can write your Jasmine specs in addition to JavaScript with CoffeeScript, fully integrated into the
Rails 3.1 asset pipeline with Jasminerice.

Please read the detailed installation and configuration instructions at [Jasminerice][].

In short, you add it to your `Gemfile`:

```ruby
group :development, :test do
  gem 'jasminerice'
end
```

and add a route for the Jasmine Test Runner to `config/routes.rb`:

```ruby
if ["development", "test"].include? Rails.env
  mount Jasminerice::Engine => "/jasmine"
end
```

Next you create the directory `spec/javascripts` where your CoffeeScript tests go into. You define the Rails 3.1
asset pipeline manifest in `spec/javascripts/spec.js.coffee`:

```coffeescript
#=require_tree ./
```

### PhantomJS

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:

```bash
$ brew install phantomjs
```

If you are using Ubuntu 10.10, you can install it with apt:

```bash
$ 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][].

## Usage

Please read the [Guard usage documentation](https://github.com/guard/guard#readme).

## Guardfile

Guard::Jasmine can be adapted to all kind of projects. Please read the
[Guard documentation](https://github.com/guard/guard#readme) for more information about the Guardfile DSL.

```ruby
guard 'jasmine' do
  watch(%r{app/assets/javascripts/(.+)\.(js\.coffee|js)}) { |m| "spec/javascripts/#{m[1]}_spec.#{m[2]}" }
  watch(%r{spec/javascripts/(.+)_spec\.(js\.coffee|js)})  { |m| "spec/javascripts/#{m[1]}_spec.#{m[2]}" }
  watch(%r{spec/javascripts/spec\.(js\.coffee|js)})       { "spec/javascripts" }
end
```

## Options

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`:

```ruby
guard 'jasmine', :all_on_start => false, :specdoc => :always do
  ...
end
```

### General options

The general options configures the environment that is needed to run Guard::Jasmine:

```ruby
:jasmine_url => 'http://192.168.1.5/jasmine'  # URL where Jasmine is served.
                                              # default: http://127.0.0.1/jasmine

:phantomjs_bin => '~/bin/phantomjs'           # Path to phantomjs.
                                              # default: '/usr/local/bin/phantomjs'

:timeout => 20000                             # The time in ms to wait for the spec runner to finish.
                                              # default: 10000
```

### Spec runner options

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

```ruby
: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.

### Specdoc options

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:

```ruby
: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
```

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 `:console` options adds captured console logs from the spec runner and adds them to the specdoc. Please note
that PhantomJS only support capturing of `console.log`, so the other log functions like `debug`, `warn`, `info` and
`error` are missing. Please vote on [Issue 232](http://code.google.com/p/phantomjs/issues/detail?id=232) if you like
to see support for more console methods coming to PhantomJS.

Another restriction on console logging is that currently only the first log parameter is passed. So instead of writing

```javascript
console.log('Debug of %o with %s', object, string)
```

your should write

```javascript
console.log('Debug of ' + object.toString() + ' width ' + string)
```

You can also give your vote on [Issue 36](http://code.google.com/p/phantomjs/issues/detail?id=36) to see support for
multiple console arguments.

### System notifications options

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

```ruby
: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
```

## A note on Rails 2 and 3

This readme describes the use of Guard::Jasmine with Jasminerice through the asset pipeline, but it is not really
a requirement for Guard::Jasmine. As long as you serve the Jasmine test runner under a certain url,
it's freely up to you how you'll prepare the assets and serve the Jasmine runner.

You can use [the Jasmine Gem][], configure the test suite in `jasmine.yml` and start the Jasmine test runner with
the supplied Rake task:

```bash
$ rake jasmine
```

Next follows an example on how to configure your `Guardfile` with the Jasmine gem:

```ruby
guard 'jasmine', :jasmine_url => 'http://127.0.0.1:8888' do
  watch(%r{public/javascripts/(.+)\.js})                  { |m| "spec/javascripts/#{m[1]}_spec.js" }
  watch(%r{spec/javascripts/(.+)_spec\.js})               { |m| "spec/javascripts/#{m[1]}_spec.js" }
  watch(%r{spec/javascripts/support/jasmine\.yml})        { "spec/javascripts" }
  watch(%r{spec/javascripts/support/jasmine_config\.rb})  { "spec/javascripts" }
end
```

You can also use [guard-process](https://github.com/socialreferral/guard-process) to start the Jasmine Gem server when
Guard starts:

```ruby
guard 'process', :name => 'Jasmine server', :command => 'bundle exec rake jasmine' do
  watch(%r{spec/javascripts/support/*})
end

JASMINE_HOST = '127.0.0.1'
JASMINE_PORT = '8888'
JASMINE_URL = "http://#{JASMINE_HOST}:#{JASMINE_PORT}/"

Thread.new do
  require 'socket'

  puts "\nWaiting for Jasmine to accept connections on #{JASMINE_URL}..."
  wait_for_open_connection(JASMINE_HOST, JASMINE_PORT)
  puts "Jasmine is now ready to accept connections; change a file or press ENTER run your suite."
  puts "You can also view and run specs by visiting:"
  puts JASMINE_URL

  guard 'jasmine', :jasmine_url => JASMINE_URL do
    watch(%r{public/javascripts/(.+)\.js})                  { |m| "spec/javascripts/#{m[1]}_spec.js" }
    watch(%r{spec/javascripts/(.+)_spec\.js})               { |m| "spec/javascripts/#{m[1]}_spec.js" }
    watch(%r{spec/javascripts/support/jasmine\.yml})        { "spec/javascripts" }
    watch(%r{spec/javascripts/support/jasmine_config\.rb})  { "spec/javascripts" }
  end
end

def wait_for_open_connection(host, port)
  while true
    begin
      TCPSocket.new(host, port).close
      return
    rescue Errno::ECONNREFUSED, Errno::EHOSTUNREACH
    end
  end
end
```

This elegant solution is provided by [Jason Morrison](http://twitter.com/#!/jayunit), see his original
[Gist](https://gist.github.com/1224382).

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:

```ruby
guard 'coffeescript', :input => 'app/coffeescripts',  :output => 'public/javascripts'
guard 'coffeescript', :input => 'spec/coffeescripts', :output => 'spec/javascripts'
```

## Guard::Jasmine for your CI server

Guard::Jasmine includes a little command line utility to run your specs once and output the specdoc to the console.

```bash
$ guard-jasmine
```

You can get help on the available options with the `help` task:

```bash
$ guard-jasmine help start
  Usage:
    guard-jasmine start

  Options:
    -u, [--url=URL]          # The url of the Jasmine test runner
                             # Default: http://127.0.0.1:3000/jasmine
    -b, [--bin=BIN]          # The location of the PhantomJS binary
                             # Default: /usr/local/bin/phantomjs
    -t, [--timeout=N]        # The maximum time in milliseconds to wait for the spec runner to finish
                             # Default: 10000
    -c, [--console=CONSOLE]  # Whether to show console.log statements in the spec runner, either `always`, `never` or `failure`
                             # Default: failure
```

By default all specs are run, but you can supply multiple paths to your specs to run only a subset:

```bash
$ guard-jasmine spec/javascripts/a_spec.js.coffee spec/javascripts/another_spec.js.coffee
```

### Travis CI integration

With the given `guard-jasmine` script you're able to configure [Travis CI](http://travis-ci.org/) to run Guard::Jasmine.
Simply use the `script` setting in your `.travis.yml`:

```yaml
script: 'bundle exec guard-jasmine'
```

You can also run your Guard::Jasmine specs after your specs that are ran with `rake` by using `after_script`:

```yaml
after_script: 'bundle exec guard-jasmine'
```

### The guard-jasmine-debug executable

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.

```bash
$ 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:

```bash
$ guard-jasmine-debug http://127.0.0.1:3000/Jasmine?spec=YourSpec
```
