We do continuous integration based on the Github Flow (scottchacon.com/2011/08/31/github-flow.html). You’ll merge your HTML+CSS+Javascript into our master build by pushing to github, which will kick off the tests on the CI, and if they pass then your push goes straight to production. So you will be expected to write and pass unit and integration tests using Karma, Mocha and Sauce Labs. You don’t have to invent this test code from scratch, just clone existing test code and adapt it to this purpose.
