Screencasts series: Writing tests for PHP source

Hey TestFesters!

That secret project I mentioned earlier is coming to life finally! :smiley: I
just released the first video (of 5!) on writing tests for PHP source. You
can find it here:

I'm planning on rolling out the next 4 videos over the course of the next
few days. I hope you find them helpful! :slight_smile:

Thanks,
