= 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>, they can stay in the Selenium gem or in <tt>/vendor/selenium</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. Selenium Core needs to be available. It could either be installed as a gem (<tt>gem install selenium</tt>) or in <tt>/vendor/selenium/</tt>.
2. Install Selenium on Rails: <tt>script/plugin install http://svn.openqa.org/svn/selenium-on-rails/selenium-on-rails</tt>
3. <i>If RedCloth 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.

=== win32-open3

win32-open3[http://raa.ruby-lang.org/project/win32-open3/] is needed if you're
on Windows and want to run your tests as a Rake task 
(see <tt>test:acceptance</tt>), i.e. you don't have to install it but it's 
recommended.

You can build it from source or install the binary:

1. Download the latest version of win32-open3, open3-0.2.2.so[http://rubyforge.org/frs/download.php/8515/open3-0.2.2.so] at the time of this writing.
2. Open up irb and run this snippet: <tt>require 'rbconfig'; include Config; puts CONFIG['sitearchdir']</tt>
3. Create a <tt>win32</tt> directory under the directory you got, e.g. <tt>c:\ruby\lib\ruby\site_ruby\1.8\i386-msvcrt</tt>
4. Rename the .so file to <tt>open3.so</tt> and put it in the <tt>win32</tt> directory.
5. Profit! (unless you get an error when doing <tt>require 'win32/open3'</tt>)

== 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

== <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.

== Todo

=== Standalone mode

More work is needed on <tt>test:acceptance</tt> on Windows to be able to start 
the server when needed.

=== user_extension.js

Selenium has support for <tt>user_extension.js</tt> which is a way to extend the 
functionality of Selenium Core. However there is currently no easy way to add
such a file in Selenium on Rails.

=== 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.
