Async testing in Jest

A presentation at React.js & React Native Berlin Meetup in in Berlin, Germany by Robin Pokorny

Jest is React’s best testing companion. It also brought several concepts to mainstream JavaScript testing: zero configuration, first-class mocking, and snapshots. With the rapid release of speed improvements, it’s easy to miss a new useful feature. Recently new async testing features were added. In this presentation, Robin shows how to use them to avoid pitfalls of false positives that often occur in tests of asynchronous code.
