To support ever shorter release cycles you need to automate testing, and to do that, you need to use a program that can verify your desired behavior. One option is to use tools that can record and replay a scenario, but those are a nightmare to maintain, and you'll probably end up writing the code needed for automating the tests yourself.
For automating the testing of a web application, Selenium is a better way. It takes some programming skills, however, and you must take care to ensure that your tests are easy to understand and maintainable.
Writing maintainable, easy to understand tests might seem hard, but not if you follow these four, simple rules of design.

This can be avoided if you strive for telling objects what to do and only ask them occasionally.
