First, some background: Hacker School is a three month writers retreat for programmers located in New York. There are no teachers or classes. My Recent Development Stack: OS X Tools « Renowned Media. I made the switch to OS X about half a year ago now, and I must admit I’m going to find it rather hard to go back to using Windows or Linux on the desktop.

Divide and Concur

Splitting Up A Large Test Suite Lately we’ve been deploying code 25 times a day or more, and running automated tests every time we deploy. Conservatively, we run our tests about 25 times on a normal business day. At Etsy, deployments are managed by engineers, not by ops or a release management team. If 15 Engineers Deploy 25 Changesets In 24 Hours… Deploys generally take about 20 minutes.

Scaling CI at Etsy: Divide and Concur, Revisited. Posted by LB Denker | Filed under engineering, infrastructure In a past post, Divide and Concur, we told you how we approached dividing our large test suite into smaller test suites by keeping similar tests together rather than arbitrarily dividing.
