For Your Own Info: Rails 2.3.2 is incompatible with Cucumber (0.8.5), Capybara (0.3.9) and Selenium-

Railers,

I am running an application on Rails 2.3.2. For some reason within our
organization, we wish to remain on this version of Rails. For
BDD/Testing,
we use Cucumber. So I installed Cucumber (0.8.5), Capybara (0.3.9) and
Selenium-webdriver (0.0.17). But when I run Cucumber on any feature, I
get
an error saying " wrong number of arguments (2 for 1)
(ArgumentError)",
(Check here for more: http://pastie.org/1169557). In addition, Selenium
web-driver was initiating two web browser windows concurrently. But, the
features were just “fine and good”.

Folks, it took me ages to figure out the problem. The error itself did
not
give a clue as to what went wrong. Neither did Cucumber inform/tip/warn
me
about anything. But after hours of trial and error, I discovered that
the
three giants, Cucumber (0.8.5), Capybara (0.3.9) and Selenium-webdriver
(0.0.17), were just incompatible with Rails 2.3.2. When I changed the
RAILS_GEM_VERSION in config/environment.rb from ‘2.3.2’ to ‘2.3.5’. The
features run awesomely cool!.

I’m glad to have solved it (and I liked the experience!!). So if anyone
is
finding the same problem with some Cucumber version (esp. >= 0.8.5 )
plus
its peripherals (Yes, I said peripherals [?][?]), hip-hop-hooray!
salvation is
here:

  • make sure you have the latest rails gem version (> 2.3.2)
  • If you would like to stick to your previous Rails version, then you
    can
    be switching between the versions. I do this manually, I would like
    to find
    a better way just automate it so that anyone ( who wishes to do so)
    can run
    the “Cukes” without problems.

Kind regards,

Do you mean that you run the tests with rails 2.3.5 but use 2.3.2 in
production? That seems like a bad idea to me.

I would say Yes and No.

Why Yes: For whatever reason, Cucumber 0.8.5 misbehaves on rails 2.3.2.
But
I still want to take advantage of it (plus its dependencies, esp.
Capybara).
After all for the features look same in both rails environments. One
using
rails 2.3.2 for testing can run them without any problems, provided they
have tools befitting it.

Why No: But for the rest of Testing (Shoulda) is done using rails 2.3.2
environment.
