Adventures in JavaScript testing

As promised, here are the slides on unit testing JavaScript from my talk at RailsConf Europe:

Adventures in JavaScript testing (PDF, 11.7 MB)

I also hear that audio (and video?) might be forthcoming, but I can’t promise anything on that. Anyway, as soon as I get some rest, I’ll also post some photos from the conference. 🙂

Off to RailsConf Europe

Tomorrow we’ll make a short trip over to London for RailsConf Europe where I’ll be talking about Adventures in JavaScript Testing.

Here’s a teaser:

I assure you, there is. Drop by my talk if you want to know more. I’ll also post the talk here on mir.aculo.us after the conference, of course.

Hope to see some of my humble readers at the conference!

script.aculo.us 1.6.4

script.aculo.us 1.6.4, which marks the inclusion of the new release candidate of Prototype 1.5, is out now.

(For those of you missing the 1.6.3 version: that version was out yesterday but had a issue with IE that is now fixed in 1.6.4)

This release comes with the brand-new Prototype V1.5.0_rc1 version, adds several new features and options to drag and drop, features a whole new (experimental) way of doing testing, and adds some other goodies here and there. Also, thanks to the contributors for identifying and squishing bugs!

So—what’s new & cool?

• Update Prototype to V1.5.0_rc1 (read more on Justin Palmer’s blog)

• Add experimental alternate syntax for unit tests (Behaviour Driven
  Development-style)

• Merge assertElementsMatch and assertElementMatches from Prototype’s
  [4986] unittest.js [Sam Stephenson]

• Add assertRespondsTo and shouldRespondTo assertions

      // object
      var testObj = {
        isNice: function() { }
      }

      // test
      assertRespondsTo('isNice', testObj);

• Make Sortable.serialize handle DOM IDs like “some_element_1” correctly, fixes #5324

• Add support for onStart, onDrag and onEnd events directly on Draggables (invoked from the Draggables.notify), fixes #4747 [thx scriptkitchen]

      new Draggable('some_id',{
        onStart:function(){ /* ... */ },
        onDrag:function(){ /* ... */ },
        onEnd:function(){ /* ... */ }
      });

• Add autoSelect option to Autocompleters to auto select an entry if only one is returned, fixes #5183 [thx cassiano dandrea]

• Added delay option to Draggables and Sortables, see test/functional/dragdrop_delay_test.html for usage, implements #3325 [thx lsimon, tomg]

• Add version and timestamp to indvidual library files for easier identification (the files are preprocessed by the Rake fresh_scriptaculous task), fixes #3015 [thx Tobie]

• Add assertIndentical and assertNotIdentical unit test assertions, which test for equality and common type, fixes #5822 [thx glazedginger]

• Add integration test for Ajax autocompleter for results with no linebreaks, #4149

• Added a custom exception to all base effects when used on non-
  existing DOM elements, added a assertRaise method to unit tests

• Add element shortcuts to Builder that can be activated by calling Builder.dump() (see the unit test), fixes #4260 [thx napalm]

      Builder.dump();
      var element = DIV({id:'ghosttrain'},[
         DIV({style:'font-size: 11px; font-weight: bold;'},[
           H1('Ghost Train'),
           "testtext", 2, 3, 4,
           UL([
             LI({onclick:'alert('test')'},'click me')
           ]),
         ]),
       ]);

• Make Effect.Puff work correctly for floating elements, fixes #3777
  [thx michael hartl]

• Fix selection of correct option in SELECT element generated by
  InPlaceCollectionEditor for indexed option arrays, fixes #4789 [thx
  steve]

• Fix an issue with redrawing ghosted draggables that are inside a
  scrolled container, fixes #3860 [thx gkupps, tsukue]

• Fix autoscrolling inside scrollable containers when window is
  scrolled too, fixes #5200 [thx wseitz]

• Fix autoscrolling when dragging an element unto a scrollable
  container, fixes #5017 [thx tomg]

• Fix a condition where overriding the endeffect on Draggables without
  overriding the starteffect too leads to a Javascript error [thx
  Javier Martinez]

• Fix a possible error with the drag/drop logic (affects the solution
  to #4706)

• Fix various issues with IE detection and Opera, and setOpacity, fixes
  #3886, #5973

• Remove revert cache code obsoleted by #4706, fixes #3436 (again) [thx
  tomg]

As always, the required 1.5.0_rc1 version of Prototype is included with the download.

Big thanks to the contributors!
