Do not waste any time trying to automate validation such as a Captcha (Completely Automated Public Turing Test To Tell Computers and Humans Apart) or other authentication system designed to thwart automation. Yes it can be done but it is effectively engaging in an arms race or tilting at windmills. More importantly it brings no value to your employer.
The right way to automate around a captcha or verification code is to configure the test environment such that the code is predictable. Many captcha tools, or verification tools, have the ability to operate in 'test' mode where they have a set response. You'd never configure a production environment that way, but you can easily (and ought to) configure a test environment that way.
Talk to the folks who setup and control the test environment. They just need some logic that knows it's a test env and then uses the proper api call for the captcha or authorization tool (like the google authorizer, or the widgets that spit out numbers every 5 minutes) to put it in test mode so it uses a predictable validation response.
Here is an example of what I am talking about: http://captcha.biz/doc/aspnet/api/captcha-configuration-reference.html#BotDetect.Configuration.ITestModeConfiguration
If you are using something that does not support this, then you can either configure the system to skip the captcha entirely, OR you can configure it to point some test stub that you create (instead of the real captcha system). This will be a small bit of code that you or your developers create that uses the same api as a real captcha, but always expects the same answer. In that case everything behaves exactly like it was talking to a real captcha service, but the little stub code it is talking to always sends the same image with the same 'answer' e.g. 'testing'
This sort of thing is normal for test environments, where all sorts of third party stuff is either disabled, or put into a test mode, or connected to a test sandbox (e.g. captcha's, advertising, website analytics, tracking pixels, credit card authorization services, etc)
