React and Redux took the world by storm. These JavaScript libraries allow you to write applications consisting of reusable components while avoiding bugs related to side-effects. But I suspect that developers do not unit test their React/Redux code. Or at least not as much as they could. During this talk, I will showcase the unit tests we have written for our eventriX product. These tests run fast and cover the most important aspects of our client-side code running in the browser. These practical real-world examples could inspire you to write more and better unit tests for your own React/Redux application.
