It’s not possible to automate the testing of CAPTCHA. That is the goal behind any good CAPTCHA strategy. By definition, a computer can’t automate it. If it could, then it’s not a good challenge that you can use in your application.
However, if you need to test an application that uses CAPTCHA, you have to work with the development team to build a workaround or a back door that allows the automated test to bypass the CAPTCHA challenge. It’s important to restrict this workaround only in the test environment and not release it to production.
