Weinre::Rails

Some helpers for integrating the awesome Weinre app with a Rails 3.1+ set up. It wouldn't take took much to use it with Rails < 3.1 as long as you're ok with getting the asset pipeline bolted in. It's assumed that if you're using this for testing with Cucumber that you'll be using something like Capybara so that you have a Javascript engine.

Installation

Add this line to your application's Gemfile:

group :cucumber, :development, :test do
    gem 'weinre-rails'
end

And then execute:

$ bundle

Or install it yourself as:

$ gem install weinre-rails

Usage

This is a very simple wrapper done as a Rails Engine which gives us Asset Pipeline goodness. To use it just put a

//= require weinre-rails

Into your application.js and you'll be off to the races. Whenever you want to connect to a Weinre server just execute:

$.connectWeinre()

from your javascript and you're good to go.

There's a handy cucumber step that lets you pause a scenario and inspect the current state of the test in Weinre. To do this include weinre-rails/cucumber in env.rb like so:

require 'weinre/rails/cucumber'

And in your scenario do something like:

Scenario: I'm testing something complicated
    Given I am doing something complicated with javascript
    When some weird condition occurs
    Then I start remote debugging
        Execution paused by weinre-rails, press enter when ready

The app will pause until you hit enter in the console at which point it will keep going.

By default the cucumber test will try to connect to:

http://localhost:8080/target/target-script-min.js#anonymous

If you want to change that you can:

Weinre::Rails.url = "http://localhost:9090/target/target-script-min.js#anonymous"
