After trying a lot of things, I tried with $.ajax() and __utils.sendAJAX() to process the form like this: response = this.evaluate(function(){ url=... params = $('form#theirForm').serialize(); data = __utils__

问题 I'm using casperjs to do some testings of a backbonejs application using localstorage. My problem is that I can not clear the localstorage when testing with casperjs.

问题 I tried to build a few casperjs tests. Went well so far but at one thing I failed: Building a test for a swipe-event. I need something like this: casper.mouse.down("#myelement"); // press and hold mousebutton casper.mouse.move_x(200); // Move mouse 200 to the right casper.mouse.up(); // Release mousebutton But there is no function like move_x in the casper-docs. Does anyone have an idea? 回答1: You can easily write your own move_x method by getting the coordinates of the selector and using

问题 I'm having a problem getting casperjs test to exit after execution, I have to hit CTL-C to exit execution. I'm on OSX 10.7 with casperjs 1.1 devel.
