Are you designing a web site and creating tests before or during its construction? Do you already have a site and want to prove that it works? A variety of design choices can help you make more robust web-based applications, from isolating the logic behind the pages to ensuring what happens when a user clicks the Submit button. The CPAN provides several modules that allow you to create useful tests for your web applications.
This chapter demonstrates how to build web applications with testing in mind as well as how to test them when you deploy them. The labs show how to record your interaction with these programs and how to validate HTML in a few different ways. Finally, the chapter walks through setting up an instance of the Apache web server specifically designed to make testing Apache modules easy.
