A few months ago, one of the teams I work with went on the hunt for a good continuous integration service for running tests on the code we write. We jumped on the unit test bandwagon at the beginning of the year and wanted to really amp up the quality of our product by having tests run on every commit. I was tasked with this job (and anyone who knows me knows I LOVE playing with new things, so it was a task I was looking forward to doing)
Most WordPress users are familiar with travis-ci.org and the internets were full of instructions for getting things plugged in and up with travis. Unfortunately, our project is inside a private github repo so we couldn’t use the free travis plan to run our tests on and the premium plan was a bit to pricey for our first attempt at this. So after searching around, I stumbled on circle. From all appearances, circle looked like it would work very similarly to travis and bonus points were that their plans are much cheaper – so great for getting started with.
