Casper.js

Casper.js is a navigation & testing utility for PhantomJS. It eases the process of defining a full navigation scenario and provides useful high-level functions, methods & syntaxic sugar for doing common tasks such as:

• defining & ordering navigation steps
• filling forms
• clicking links
• capturing screenshots of a page (or an area)
• making assertions on remote DOM
• logging events
• downloading base64 encoded resources, even binary ones
• catching errors and react accordingly
• writing functional test suite, exporting results as JUnit XML (xUnit)
