Notes about capybara's examples which are failing for capyabara-zombie

Capybara Zombie

  1) Capybara::Driver::Zombie it should behave like driver with javascript support#drag_to should drag and drop an object
     Failure/Error: @driver.find('//div[contains(., "Dropped!")]').should_not be_empty
     expected empty? to return false, got true

          jQuery draggable.start and draggable.stop events are fired.

          jQuery('#drag').offset() is {top: NaN, left: NaN} <== JSDOM doesn't implement element position; I think jQuery cares about this...
            NB: env-js does not implement position either
            NB: it looks like html_unit does
            NB: droppable is not raising 'over': jquery.ui.droppable.js uses $.ui.intersect to test for intersection.

          If I specify :pageX and :pageY (10, 136), I see this error now:

  2) Capybara::Driver::Zombie it should behave like session with javascript support all JS specs Node#drag_to should drag and drop an object
     Failure/Error: @session.find('//div[contains(., "Dropped!")]').should_not be_nil
     Unable to find '//div[contains(., "Dropped!")]'
     
          IGNORE: SAME AS FAILURE #1




  3) Capybara::Driver::Zombie it should behave like session with javascript support all JS specs#wait_until should wait for block to return true
    Failure/Error: @session.evaluate_script('activeRequests == 1').should be_true
    expected false to be true

        This has something to do with script execution contexts

         - $('#waiter').change is fired.
         - setTimeout works
         - but @session.evaluate_script('activeRequests') is _always_ whatever value `activeRequests` is given on line 1 of test.js
        
        I believe this is the same as [issue #37](https://github.com/assaf/zombie/issues/issue/37)

This failure was occurring because jQuery expected the 'click' event to be fired when the checkbox's value was changed.
4) Capybara::Driver::Zombie it should behave like session with javascript support all JS specs#check should trigger associated events
Failure/Error: @session.should have_css('#checkbox_event_triggered');
