Continuously testing React applications with Jest and Enzyme

February 05, 2019

React has taken the frontend world by storm, and for a good reason. It provides an intuitive model for building data-driven user interfaces. React enables us to write declarative components describing the user interface and provide the data needed to render these interfaces. It then efficiently updates the DOM when this data changes. Redux, on the other hand, enables managing the data that React needs to render interfaces. It offers a predictable way to structure and update the data in frontend applications and pairs quite nicely with React.

In this post, we will explore how to go about writing tests for an existing React and Redux application. We will then configure continuous integration with CircleCI, to automate the testing and ensure that any new code we add does not break the existing functionality.
