A simple test assertion DSL

Why?

I am not good at writing bug-free code in JavaScript or CoffeeScript. I am equally not good at writing bug-free tests. It would be nice to have a way to quickly build a basic 'safety net' for my code, and be able to describe the tests in a format less verbose than 'describe->it-should->etc'.

It should also be a good learning experience.

How do you create a CoffeeScript class instance using 'apply'?

How do you create a CoffeeScript class instance using 'apply'?

The answer is, like this:

util = require('util')
assert = require('assert')

class MyClass
	constructor: (@splatArgs...) -> @first = splatArgs[0]; @second = splatArgs[1]

Debugging ASP.NET MVC 4 model binding

The Scenario

Recently we had a tricky defect raised where, under certain circumstances, the user-entered values were not being persisted. The page was a somewhat complex data entry form, with many fields, lots of validation, and a complex hierarchy of view model objects and controls/helpers.

The process

After reproducing the issue (which itself was difficult), the first thing we did was to attach the debugger and set a break point on the first line of the controller action.
