I am looking for RoR Webrat Selenium Install Recipe

[Audrey A Lee]

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.

Hi Audrey,

Shot in the dark: is Webrat set up to access port 3001 while your Rails app is actually on port 3000?

That might explain the timeout.
