Is it possible to globally increase Watir-Webdriver when_present wait time?

Question

I am writing an automated testing program which will test some web programs that are sometimes slow to load certain AJAX calls. For instance the user will click \'Query\' wh

Update: This monkey patch has been merged into watir-webdriver and so will no longer be needed in watir-webdriver v0.6.5. You will be able to set the timeout using:

Watir.default_timeout = 90

The wait methods are defined similar to:

def when_present(timeout = 30)
  message = "waiting for #{selector_string} to become present"

  if block_given?
    Watir::Wait.until(timeout, message) { present? }
    yield self
  else
    WhenPresentDecorator.new(self, timeout, message)
  end
end

As you can see, the default timeout of 30 seconds is hard-coded. Therefore, there is no easy way to change it everywhere.

However, you could monkey patch the wait methods to use a default time and set it to what you want. The following monkey patch will set the default timeout to 90 seconds.

require 'watir-webdriver'
module Watir

  # Can be changed within a script with Watir.default_wait_time = 30    
  @default_wait_time = 90  
  class << self
    attr_accessor :default_wait_time    
  end

  module Wait

    class << self
      alias old_until until
      def until(timeout = Watir.default_wait_time, message = nil, &block)
        old_until(timeout, message, &block)
      end

      alias old_while while
      def while(timeout = Watir.default_wait_time, message = nil, &block)
        old_while(timeout, message, &block)
      end

    end # self
  end # Wait

  module EventuallyPresent

    alias old_when_present when_present
    def when_present(timeout = Watir.default_wait_time, &block)
      old_when_present(timeout, &block)
    end

    alias old_wait_until_present wait_until_present
    def wait_until_present(timeout = Watir.default_wait_time)
      old_wait_until_present(timeout)
    end

    alias old_wait_while_present wait_while_present
    def wait_while_present(timeout = Watir.default_wait_time)
      old_wait_while_present(timeout)
    end

  end # EventuallyPresent
end # Watir

Include the patch after the watir webdriver code is loaded.
