Adding additional configuration args to selenium rc using cucumber and webrat

Rob — Thu, 25 Feb 2010 14:30:50 +0000

I use cucumber, webrat and selenium RC a lot day to day, all are great pieces of kit, which make my life so much easier, but I’m always trying to find ways to make these ever easier.
Selenium RC has alot of options which are settable when booting the selenium-server java application.
Many of these options are not available when using selenium with cucumber and webrat.

I have raised an issue for webrat and produced a patch that enables you to pass additional arguments during the setup of your webrat instance, these are then passed on to the Selenium RC startup command.

Until this is prioritised and added to the webrat core, I have an on-the-fly solution that enables the additional args, the following code should be added to your `env.rb`

attr_accessor :selenium_additional_args
end
end

module AdditionalArgs
def self.included(base)
base.alias_method_chain :start, :additional_args
end

def start_with_additional_args
remote_control.additional_args = Webrat.configuration.selenium_additional_args
start_without_additional_args
end
end

Webrat.configure do |config|
...
config.selenium_additional_args = ["-firefoxProfileTemplate '../../Library/Application Support/Firefox/Profiles/selenium'", "-singleWindow"]
...
end

Webrat::Selenium::SeleniumRCServer.send(:include, AdditionalArgs)

Testing ActionMailer models with Rspec

Rob — Mon, 14 Dec 2009 11:41:05 +0000

You might think testing ActionMailer sounds like a challenge, actually it’s just as easy as testing other classes, you just have to know the methods to use to change the state/content of the deliveries.

Here we have a simple example of how you might test a mailer for your order receipt

describe "and delivered" do

it "should be added to the delivery queue" do

Cucumber pretty html formatter for textmate

Rob — Wed, 26 Aug 2009 11:23:48 +0000

I’ve been using cucumber a lot recently along with the textmate bundle for it.
The HTML output cucumber creates is fine, but not all that pretty.

I’ve created a new formatter for cucumber to generate HTML enhanced with some javascript.
My inspiration came from the textmate bundle for rspec.

You can grap it off my github.
Here’s some screenshots:

UPDATE: I replaced the original html formatter in cucumber; as of 19th November my fork has been merged into Aslak’s cucumber/master upgrade to the cucumber 0.4.5 release.
