I have a script which contains class extensions. The Checkbox.test() is  
obviously just a stub right now, but I’m trying to get my head around  
the concept.

#-- contained in classExtensions.rb  
module Watir

class Checkbox \< Watir::RadioCheckCommon

```
def test(property, expectedResult)
  puts("Checkbox.test()")
end

```

end

end

In another script, I have the following…

require ‘watir’  
require ‘sqlClient’  
require ‘classExtensions’

.  
.  
.

ie.checkboxes.each {|cb|  
cb.test(“jfkdsajf”, “jfkdlas”, “jfkdlasjf”)  
}

However, I’m getting the following error:  
#\<NoMethodError: private method `test’ called for #Watir::CheckBox\>

What am I doing wrong here?

I googled “extending watir” and found this…  
[http://wiki.openqa.org/pages/viewpage.action?pageId=1119](http://wiki.openqa.org/pages/viewpage.action?pageId=1119), which got me  
pointed in the right direction. Here’s the definition of the class  
extension, although I must admit I don’t fully understand it. At any  
rate, when I run the test script, “test” is now listed as _public_  
method.

class Watir::CheckBox

def test(property, expectedResult)  
puts(“CheckBox.test("#{property}", "#{expectedResult}")”)  
end

end

Bret, in response to your query… I’m having to modify the way we are  
checking properties on web page controls; visible, enabled, disabled…  
blahblah, in order to “conform” to a new way my supervisor wants tests  
run. When I started on this project, I was looking at the forms and  
running the tests on each form as a whole. We are now breaking the forms  
down to their individual components and testing each one, comparing the  
expected test results, contained in a SQL Server table, with the actual  
result. I only wish someone had thought about that 3-months ago,  
probably should’ve been me actually. Most of the work already done by  
myself and a coworker will have to be re-written to conform to the new  
testing “model”. Oh well… it beats standing in a line!
