mocking up a resource definition

summary

each resource file, say api/enamel/1.0/infoset.js, defines an ancestor of the Model class. the resource class has a __requests__ member that defines mesh/request instances for each request (get, put, post, query, delete, etc). each of these request instances has an ajax method that's just a reference to $.ajax, and it uses that do actually make the xhr.

'mocking' a resource amounts to the following:

unit testing -- from test.js to continuous integration

unit testing

unit tests are good for number of reasons, but it's important to know when writing them is worth the time effort. we're not dogmatic about TDD, but we try to make it as easy as possible for the developer to write meaningful tests.

when deciding whether or not to write a test, keep the following in mind:

  • javascript is INSANELY dynamic, so refactoring can cause a lot of subtle bugs, and it's nearly impossible without good unit tests. in as much as you

we should probably get some unit tests around the following corner cases:

  1. collection load's
  2. a collection has been loaded and includes a particular model
  3. that model is updated server-side, not on the page
  4. the collection is re-loaded, and the change from the server side is applied to the local copy of the model
  5. i don't know if the model triggers a change event in this case
  6. pertinent code: when a query resolves and converts the plain objects into model instances

finding global variables

good unit tests framesworks in javascript will throw errors when you leak global variables. it can be massively difficult to trace down the offending lines of code in a large application. a quick and effective fix is to add the attached bit of javascript at the beginning of your application and open your debugger (chrome dev tools, firebug, node debugger, etc.).

you'll get a break point at the error and it's easy to fix from there.

i've tried to download the last part of the IE9 Windows 7 VM from the [modern.ie](http://www.modern.ie/en-us/virtualization-tools#downloads) site numerous times, and it's never the correct file. the strange thing is it seemed to work for parts 1-4, but 5 keeps failing.
