#JavaScript Unit Testing Tips and Tricks#

###Please add your your tips and tricks for unit testing JavaScript as comments to this gist. I'll pull them into the main text and credit your contribution.###

Create/use snippits to scaffold testing methods ( i.e. if you are using BDD scaffold describe and it methods)
Write tests with the same care as production code
DRY. Factor out repeated code into methods

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

Just install this in your apps like so:

gem 'test-spec-mini', :git => 'git://gist.github.com/1806986.git', :require => 'mini'

	// Handle back button issues with Twitter Bootstrap's tab component.
	// Based on: http://stackoverflow.com/a/10120221/81769
	// It has been changed to avoid the following side effects:
	// - Switching tabs was being added to navigation history which is undesirable
	// (Worked around this by using location.replace instead of setting the hash property)
	// - Browser scroll position was lost due to fragment navigation
	// (Worked around this by converting #id values to #!id values before navigating.)
	$(document).ready(function () {

	if (location.hash.substr(0,2) == "#!") {

	# Here's a contrived example of a LEFT JOIN using ARel. This is an example of
	# the mechanics, not a real-world use case.
