CasperJS 
CasperJS is a navigation scripting & 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 suites, exporting results as JUnit XML (xUnit)
