Introduction with CasperJS

CasperJS is an open source navigation scripting & testing utility written in Javascript for the PhantomJS WebKit headless browser and SlimerJS (Gecko). It eases the process of defining a full navigation scenario and provides useful high-level functions, methods & syntactic sugar for doing common tasks such as:

• defining & ordering browsing navigation steps
• filling & submitting forms
• clicking & following links
• capturing screenshots of a page (or part of it)
• testing remote DOM
• logging events
• downloading resources, including binary ones
  writing functional test suites, saving results as JUnit XML
• scraping Web contents
