Test all the things! Code hinting Unit testing Functional testing
Frontend :( • Testing is hard weird • Not sure
what to test • TIMTOWTDI
How I learned to stop worrying and love tests.
Why How I learned to stop worrying and love tests.
editor holy war hard vs soft tabs code readability syntax
consistency team.length > 1
comments are lies documentation is fiction intent !== effect document
behaviour, not implementation // this is not a doc
downtime is $ never deploy a broken app env.production =
true;
N builds / day triggered by any developer who broke
the build? ship it
Then how?
It's the little things: line length, camel casing, tabs/spaces, ...
Benevolent dictator of syntax JSHint
nodeunit DRY bug fixing Behaviour is documented, implementation is verified.
"How did that utility work again?"
CasperJS Run high-level tests on a headless WebKit "Do all
our features still work?"
