= Selenium on Rails == Overview Selenium on Rails provides an easy way to test Rails application with SeleniumCore[http://www.openqa.org/selenium-core/]. This plugin does four things: 1. The Selenium Core files don't have to pollute <tt>/public</tt>. 2. No need to create suite files, they are generated on the fly -- one suite per directory in <tt>/test/selenium</tt> (suites can be nested). 3. Instead of writing the test cases in HTML you can use a number of better formats (see <tt>Formats</tt>). 4. Loading of fixtures and wiping of session (<tt>/selenium/setup</tt>). == Installation 1. Install Selenium on Rails: <tt>script/plugin install http://svn.openqa.org/svn/selenium-on-rails/selenium-on-rails</tt> 2. If you're on Windows, <tt>gem install win32-open3</tt> 3. <i>If the RedCloth gem is available the Selenese test cases can use it for better markup.</i> 4. Run the Rakefile in the plugin's directory to run the tests in order to see that everything works. (If RedCloth isn't installed a few tests will fail since they assume RedCloth is installed.) 5. Create a test case: <tt>script/generate selenium login</tt> 6. Start the server: <tt>script/server -e test</tt> 7. Point your browser to <tt>http://localhost:3000/selenium</tt> 8. If everything works as expected you should see the Selenium test runner. The north east frame contains all your test cases (just one for now), and the north frame contains your test case. == Formats The test cases can be written in a number of formats. Which one you choose is a matter of taste. You can generate your test files by running <tt>script/generate selenium</tt> or by creating them manually in your <tt>/test/selenium</tt> directory. === Selenese, .sel Selenese is the dumbest format (in a good way). You just write your commands delimited by | characters. |open|/selenium/setup| |open|/| |goBack| If you don't want to write Selenese tests by hand you can use SeleniumIDE[http://www.openqa.org/selenium-ide/] which has support[http://wiki.openqa.org/display/SIDE/SeleniumOnRails] for Selenese. SeleniumIDE makes it super easy to record test and edit them. === RSelenese, .rsel RSelenese enable you to write your tests in Ruby. setup :fixtures => :all open '/' assert_title 'Home' ('a'..'z').each {|c| open :controller => 'user', :action => 'create', :name => c } See SeleniumOnRails::TestBuilder for available commands. === HTML/RHTML You can write your tests in HTML/RHTML but that's mostly useful if you have existing tests you want to reuse. === Partial test cases If you have some common actions you want to do in several test cases you can put them in a separate partial test case and include them in your other test cases. A partial test case is just like a normal test case besides that its filename has to start with _: #_login.rsel open '/login' type 'name', name type 'password', password click 'submit', :wait=>true To include a partial test case you write like this in a Selenese test case: |includePartial|login|name=John Doe|password=eoD nhoJ| in a RSelenese test case: include_partial 'login', :name => 'Jane Doe', :password => 'Jane Doe'.reverse and in a RHTML test case: <%= render :partial => 'login', :locals => {:name = 'Joe Schmo', :password => 'Joe Schmo'.reverse} %> == Configuration There are a number of settings available. You make them by renaming <tt>config.yml.example</tt> to <tt>config.yml</tt> and make your changes in that file. === Environments Per default this plugin is only available in test environment. You can change this by setting <tt>environments</tt>, such as: #config.yml environments: - test - development === Selenium Core path If you don't want to use the bundled Selenium Core version you can set <tt>selenium_path</tt> to the directory where Selenium Core is stored. #config.yml selenium_path: 'c:\selenium' == <tt>test:acceptance</tt> You can run all your Selenium tests as a Rake task. First, if you're on Windows, you have to make sure win32-open3 is installed. Then you have to configure which browsers you want to run, like this: #config.yml browsers: firefox: 'c:\Program Files\Mozilla Firefox\firefox.exe' ie: 'c:\Program Files\Internet Explorer\iexplore.exe' Now you're all set. First start a server: script/server -e test Then run the tests: rake test:acceptance Now it should work, otherwise let me know! === Store results If you want to store the results from a <tt>test:acceptance</tt> you just need to set in which directory they should be stored: #config.yml result_dir: 'c:\result' So when you run <tt>rake test:acceptance</tt> the tables with the results will be stored as <tt>.html</tt> files in that directory. This can be useful especially for continous integration. === user_extension.js Selenium has support for <tt>user_extension.js</tt> which is a way to extend the functionality of Selenium Core. Selenium on Rails now provides the means for you to extend it's functionality to match. To get you started, we've included the example files <tt>lib/test_builder_user_accessors.rb.example</tt> and <tt>lib/test_builder_user_actions.rb.example</tt> that replicate the sample extensions in Selenium Core's <tt>user-extensions.js.sample</tt> To get these examples running, simply remove the .example and .sample extensions from the files and restart your server. == Todo === Standalone mode More work is needed on <tt>test:acceptance</tt> on Windows to be able to start the server when needed. === More setup/teardown support? Currently there is only support to load fixtures and to wipe the session in <tt>/selenium/setup</tt>. Is there a need for more kinds of setups or teardowns? === More documentation == Not todo === Editor Creating an editor for the test cases is currently considered out of scope for this plugin. SeleniumIDE[http://www.openqa.org/selenium-ide/] does such a good job and has support[http://wiki.openqa.org/display/SIDE/SeleniumOnRails] for the Selenese format. == Credits * Jon Tirsen, http://jutopia.tirsen.com -- initial inspiration[http://wiki.rubyonrails.com/rails/pages/SeleniumIntegration] * Eric Kidd, http://www.randomhacks.net -- contribution of RSelenese == Information For more information, check out the website[http://www.openqa.org/selenium-on-rails/].
