ross boucher - quality control: testing and debugging your apps
DESCRIPTION
Developers have long been able to use an array of debugging, profiling and other testing tools to ensure application quality and performance. More recently, web developers have started to rely on increasingly sophisticated tools to help test their web sites and applications. But particularly in the mobile space, when developing sophisticated applications with web technologies, testing presents significant challenges. Ross Boucher, one of the developers of Objective-J, the Cappuccino web application framework, the visual development tool Atlas, and 280 slides knows a thing or two about testing sophisticated applications developed using web technologies. In this session, he’ll share some of those secretes, and help you better test and debug your applications.TRANSCRIPT

alert()
I suspect that most JavaScript developers out there are a lot like me... We want to be able to pause our scripts, look at the call stack, and step through them one line at a time, but it's easier to just use "alert debugging" than to fire up a big clunky debugger.
