Broadly understood, testability defines the limits on producing and releasing complex systems with an acceptable risk of costly or dangerous defects. This talk will explore testability, consider what we know about how it, and challenge the audience with some open problems.

Testing, Performance Analysis and jQuery 1.4

Published February 22nd, 2010 Under Performance Testing | Leave a Comment

In the first part of the talk, John reviewed the range of tools available to frontend engineers for unit testing and for analyzing the performance of code. In the latter case, he argues for going beyond pure speed-based benchmarks to structural analyses of performance. By looking at structure, the jQuery team was able to identify and correct bottlenecks, resulting in major performance improvements in the upcoming 1.4 release. In the second part of the talk (beginning at 49:20 in the video), John reviews some of those jQuery 1.4 changes. In the short third section (beginning at 1:03:15), he looks at some interesting trends he’s noticed in the practical application of new HTML 5 elements — especially in older browsers.

Extreme JS Performance

Published February 3rd, 2010 Under Performance Testing, Software Testing | Leave a Comment

You serve up your code gzipped. Your caches are properly configured. Your data (and scripts) are loaded on-demand. That’s awesome—so don’t stop there. Runtime is another source of slowdowns, and you can learn to conquer those, too. Learn how to profile & benchmark your code to isolate performance issues, and what to do when you find them. The techniques you’ll learn range from the normal (clean up after yourself) to the extreme (unrolling loops).
