Picking Jest over Mocha – testing tools comparison

At Automattic we use Mocha to run all tests written for Calypso project which powers WordPress.com. It also includes end-to-end tests, which live in their own repository. We have been using this setup for over 3 years now. I think it is a good moment to revisit this choice. I found this unit testing tools comparison very helpful when evaluating alternatives. I strongly agree with the conclusions shared by Martin Olsson in his article:

Staying with Javascript, I think it’s hard to ignore the momentum behind Jest. I would be awesome if someone fixed #2059 though. Then again, Mocha seems to work well enough for a lot of people.

Functional Light JavaScript workshop

Functionite company did an impressive job bringing JavaScript expert Kyle Simpson to their hometown Warsaw, Poland in September last year. He lead You Don’t Know JS Workshops, 5 days of JavaScript classes focused on learning new skills and the best practices. I joined on the last day to attend an excellent workshop titled Functional-Light JavaScript. In this post I wanted to share slides and my coding exercises from this course. If you are curious what topics related to functional programming were covered I strongly recommend checking notes from a similar workshop shared by Beth Allchurch.

Dubrovnik, Croatia

At Automattic we are encouraged to consider a team switch from time to time. Team switches help to bring fresh perspective to different projects the company is working on and provide opportunities to learn new skills. I decided to take advantage of this chance and joined team Amber in the middle of October. The timing could not be better, only a few days later I was invited to join my new team mates in Dubrovnik to work on get.blog – domain name registrar for .blog domains.

Automattic Grand Meetup 2016

Automattic gets the whole company together once a year for seven days so that employees can meet in person, work on projects, take classes and hang out together. It’s extremely important because we all work from home on a daily basis and see each other mostly online. Last year I had a lot of fun at the Grand Meetup in Park City, Utah and this year it felt even better to be around almost 500 Automatticians in Whistler, British Columbia.

Calypso

Calypso is the codename for a WordPress.com admin interface. This is what I wrote about it in one of my previous posts:

This is a universal (aka isomorphic) JavaScript single page app written in ES6 using webpack, express, ReactFlux Redux, WordPress Rest API and many other front-end libraries.
