I am looking for RoR Webrat Selenium Install Recipe

Hi there,

I''m trying to follow the ch 22 of the RSpec book.
[ copy is (B11.0 printing, October 28, 2009) ]

I want to use selenium and cucumber.

Ordinary webrat seems to be working well.

Here is info about my RoR:

I installed these 2 gems and unpacked them in vendor gems:

drwxr-xr-x   7 maco  staff  238 Nov  7 21:04 Selenium-1.1.14/
drwxr-xr-x   7 maco  staff  238 Nov  7 21:05 selenium-client-1.2.17/

Here are the corresponding config.gem lines in config/environment.rb:

  config.gem ''selenium-client'', :lib => false, :version
=> ''1.2.17''
  config.gem ''Selenium'', :lib => false, :version =>
''1.1.14''

I edited this file:

features/support/env.rb

So it matches this file supplied by the RSpec book:

http://media.pragprog.com/titles/achbd/code/simulated_browser/03/features/support/env.rb

The book-file has a bug which I commented out:

  # config.selenium_wait_timeout = 10


When I run cucumber I see this:

It looks like Selenium-RC is getting started.

But I sense that Selenium-RC is broken or my call to script/cucumber
cannot connect to Selenium-RC.

Is there a recipe for getting cucumber and selenium to work together.

It worries me that the RSpec book is not specific about gem versions.

I''d like to see a recipe which has a very specific list of ingredients
I need in order to operate cucumber with Selenium.

Can anyone offer a clue?

Thanks.

Re: I am looking for RoR Webrat Selenium Install Recipe

ok,

I made some progess debugging this.

I downloaded software from here:
  -
http://release.seleniumhq.org/selenium-remote-control/1.0.1/selenium-remote-control-1.0.1-dist.zip

I verified that Selenium Remote Control works on my Mac using this
tutorial:
  - http://www.jroller.com/selenium/#steps

Above tutorial tells me I can start selenium-remote-control with a
simple shell command:
  - /usr/bin/java -jar selenium-server-1.0.1/selenium-server.jar -
multiwindow

Then I exported a test-case (in ruby format) using Selenium IDE:

require "rubygems"
require "selenium"
require "test/unit"

class SelTestCase20091108 < Test::Unit::TestCase
  def setup
    @verification_errors = []
    if $selenium
      @selenium = $selenium
    else
      @selenium = Selenium::SeleniumDriver.new("localhost", 4444,
"*chrome", "http://www.google.com/", 10000);
      @selenium.start
    end
    @selenium.set_context("SelTestCase20091108")
  end

  def teardown
    @selenium.stop unless $selenium
    assert_equal [], @verification_errors
  end

  def test_sel_test_case2009_1108
    @selenium.open "/"
    @selenium.type "q", "selenium remote control"
    @selenium.click "btnG"
    sleep 66
  end
end


I was able to run above test-case with no problem:
  - ruby sel_test_case2009_1108.rb

At that point it dawned on me that the Selenium-server started by my
Cucumber was broken.

And I recognized that the Selenium-server I had started by hand was
ok.

So, I started the Selenium-server by hand using this shell command:
  - /usr/bin/java -jar selenium-server-1.0.1/selenium-server.jar -
multiwindow

Then, in another terminal I ran this:

script/cucumber features/welcome_page.feature

Cucumber complained that port 4444 was taken but that is a good thing
because broken-Selenium-server could not start.

After 7 seconds, 2 firefox windows came to life and Cucumber walked
through some steps.

Some of the matchers malfunctioned but I feel like I am making some
progress.

Recap:
  - Cucumber wants to start a broken Selenium-server
  - I prevent that by starting a  selenium-server-1.0.1 by hand before
I run Cucumber

Re: I am looking for RoR Webrat Selenium Install Recipe

Audrey,  
I would suggest, a few things... 
1. Updating webrat, selenium-client to the most recent versions and cucumber to
at least 0.4.2.  Don't forget to run script/generate cucumber after you
update the cucumber gem.
2.  Also you do not need the selenium gem as selenium server comes prepackaged
with webrat, in its vendor folder.
3.  After you're up and running using those gems its a good idea to separate
your features or scenarios into two different profiles, plain and enhanced for
your rails and selenium modes respectively.  A good how to for this is on Aslak
Hellesoy's cucumber github wiki page for selenium.
http://wiki.github.com/aslakhellesoy/cucumber/setting-up-selenium .  Please note
the update at the top of the page.

I've found that not all versions of webrat work with all versions of
cucumber but the most recent of both gems work well for me. Btw, I'm
running:
Selenium-client 1.2.17
Cucumber 0.4.2
Webrat 0.5.3
Dbcleaner 0.2.3 
Rails 2.3.2
Ruby 1.8.6 pl 287   

If all else fails I would try the webrat list: webrat@googlegroups.com.
