- Simpler API, less boilerplate code.
- Flexible and easy configuration.
- Test files executed in isolation.
- Advanced watch mode.
- Snapshots support = easier start with testing.
- Code coverage.
- Another migration.
- Mocha has still a bit better performance (according to my quick tests).
My analysis got very positive feedback, with only a few little concerns, so I got encouraged to take action and verify the assumptions stated. I picked two different projects to play with to ensure both of them will uniformly benefit from using Jest.
I had an opportunity to attended React Native EU 2017 conference last month. This 2 days long event took place in my hometown Wrocław, Poland. It was a very interesting experience for me because I’m a frontend developer. I don’t have any working experience with React Native and the only mobile project I worked on was built using Apache Cordova. Anyway, I found many of the talks very attractive and I wanted to highlight some of them in this post.
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:
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 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.
FluxRedux, WordPress Rest API and many other front-end libraries.
