capybara-webkit =============== [![Build Status](https://secure.travis-ci.org/thoughtbot/capybara-webkit.png?branch=master)](https://travis-ci.org/thoughtbot/capybara-webkit) [![Code Climate](https://codeclimate.com/github/thoughtbot/capybara-webkit.png)](https://codeclimate.com/github/thoughtbot/capybara-webkit) A [capybara](https://github.com/jnicklas/capybara) driver that uses [WebKit](http://webkit.org) via [QtWebKit](http://trac.webkit.org/wiki/QtWebKit). Qt Dependency and Installation Issues ------------------------------------- capybara-webkit depends on a WebKit implementation from Qt, a cross-platform development toolkit. You'll need to download the Qt libraries to build and install the gem. You can find instructions for downloading and installing QT on the [capybara-webkit wiki](https://github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit). capybara-webkit requires Qt version 4.8 or greater. Windows Support --------------- Currently 32-bit Windows will compile capybara-webkit. Support for Windows is provided by the open source community and Windows related issues should be posted to [Stack Overflow]. [Stack Overflow]: http://stackoverflow.com/questions/tagged/capybara-webkit Reporting Issues ---------------- Without access to your application code we can't easily debug most crashes or generic failures, so we've included a debug version of the driver that prints a log of what happened during each test. Before filing a crash bug, please see [Reporting Crashes]. You're much more likely to get a fix if you follow those instructions. If you're having trouble compiling or installing, please check out the [wiki]. If you don't have any luck there, please post to [Stack Overflow]. Please don't open a Github issue for a system-specific compiler issue. [Reporting Crashes]: https://github.com/thoughtbot/capybara-webkit/wiki/Reporting-Crashes [capybara-webkit wiki]: https://github.com/thoughtbot/capybara-webkit/wiki [Stack Overflow]: http://stackoverflow.com/questions/tagged/capybara-webkit CI -- If you're like us, you'll be using capybara-webkit on CI. On Linux platforms, capybara-webkit requires an X server to run, although it doesn't create any visible windows. Xvfb works fine for this. You can setup Xvfb yourself and set a DISPLAY variable, try out the [headless gem](https://github.com/leonid-shevtsov/headless), or use the xvfb-run utility as follows: ``` xvfb-run -a bundle exec spec ``` This automatically sets up a virtual X server on a free server number. Usage ----- Add the capybara-webkit gem to your Gemfile: ```ruby gem "capybara-webkit" ``` Set your Capybara Javascript driver to webkit: ```ruby Capybara.javascript_driver = :webkit ``` In cucumber, tag scenarios with @javascript to run them using a headless WebKit browser. In RSpec, use the `:js => true` flag. See the [capybara documentation](http://rubydoc.info/gems/capybara#Using_Capybara_with_RSpec) for more information about using capybara with RSpec. Take note of the transactional fixtures section of the [capybara README](https://github.com/jnicklas/capybara/blob/master/README.md). If you're using capybara-webkit with Sinatra, don't forget to set ```ruby Capybara.app = MySinatraApp.new ``` Offline Application Cache ------------------------- The offline application cache needs a directory to write to for the cached files. Capybara-webkit will look at if the working directory has a tmp directory and when it exists offline application cache will be enabled. Non-Standard Driver Methods --------------------------- capybara-webkit supports a few methods that are not part of the standard capybara API. You can access these by calling `driver` on the capybara session. When using the DSL, that will look like `page.driver.method_name`. **console_messages**: returns an array of messages printed using console.log ```js // In Javascript: console.log("hello") ``` ```ruby # In Ruby: page.driver.console_messages => [{:source=>"http://example.com", :line_number=>1, :message=>"hello"}] ``` **error_messages**: returns an array of Javascript errors that occurred ```ruby page.driver.error_messages => [{:source=>"http://example.com", :line_number=>1, :message=>"SyntaxError: Parse error"}] ``` **cookies**: allows read-only access of cookies for the current session ```ruby page.driver.cookies["alpha"] => "abc" ``` **header**: set the given HTTP header for subsequent requests ```ruby page.driver.header 'Referer', 'https://www.thoughtbot.com' ``` **block_unknown_urls**: By default, capybara-webkit will warn when a request is made to a URL other than 127.0.0.1 or localhost. This option will block such unknown URLs instead. ```ruby page.driver.block_unknown_urls ``` **allow_url**: Allow requests to a URL. This will silence unknown URL warnings, or permit requests to a URL when `block_unknown_urls` is used. Allowed URLs are reset on `Driver#reset!`. ```ruby page.driver.allow_url 'example.com/*.js' ``` Contributing ------------ See the CONTRIBUTING document.
