At last night’s FESuffolk meeting I gave a lightning talk on getting started with unit-testing Javascript/coffeescript using jasmine-headless-webkit. I made a screen recording, so if you missed it you can still experience my frantic babbling (I had Keynote set to auto-advance, using the Ignite 20 × 15 second slide format, and as usual I tried to cram too much into each slide).
If you don’t want to watch the recording, you can look at the slides and guess what I might have been saying, read the example code (the commits try to build up in small steps), or just play with the utterly pointless app that the example implements.
