I will be putting together an application to automate an external web site/application. In some instances I will need to navigate the site as a user would (some links I need to follow cannot be predicted and must be parsed from a response)
Are there any other technologies I should be aware of?
Are there any recommended patterns for being able to quickly adjust in the event that the external web app changes? I’m envisioning encapsulating the validation of responses as some type of strategy or similar pattern that can be easily separated/plugged in as necessary, but any specific suggestions would be great.
