SlimerJS — A scriptable browser for Web developers

SlimerJS allows you to interact with a web page through an external JS script. It is useful to do functional tests, page automation, network monitoring, screen capture, etc.

webpage
  .open(url) // loads a page
  .then(function(){ // executed after loading
    // store a screenshot of the page
    webpage.viewportSize =
        { width:650, height:320 };
    webpage.render('page.png',
                   {onlyViewport:true});
    // then open a second page
    return webpage.open(url2);
  })
  .then(function(){
    // click somewhere on the second page
    webpage.sendEvent("click", 5, 5,
                        'left', 0);
    slimerjs.exit()
  });

Sounds familiar? It does:

SlimerJS is similar to PhantomJs, except that it runs Gecko, the browser engine of Mozilla Firefox, instead of Webkit (And it is not yet truly headless).

Also plays nice with CasperJS (1.1-beta)
