UI or User Interface test is a form of acceptance testing done to verify the user flows of your front-end application. The emphasis of these kinds of software tests is on the end-user that is the actual person who will be interacting with your web application on a variety of devices ranging from desktops, laptops to mobile devices. In this final part of Mirage JS Deep Dive series, Kelvin Omereshone will be putting everything you’ve learned in the past series into learning how to perform UI tests with Mirage JS.

In this article, we’re going to learn how to use Immer to write reducers. When working with React, we maintain a lot of state. To make updates to our state, we need to write a lot of reducers. Manually writing reducers results in bloated code where we have to touch almost every part of our state. This is tedious and error-prone. In this article, Chidi Orjil going to see how Immer brings more simplicity to the process of writing state reducers.

So far, we have seen how we can create records with Mirage, intercept API requests via route handlers and, last but not least, how the shape of the data returned to us from Mirage is affected. In this third part of Mirage JS Deep Dive series, Kelvin Omereshone will be focusing on using response, timing and passthrough in Mirage for a better handle on simulating an actual backend server. However, before you begin reading this article, please read the introduction to MirageJS first as well as Part 1 and Part 2 of this series.

In this article, Chidi Orji will explore the concept of error boundaries in a React application. You’ll work through an example app to see how we can use error boundaries to deliver a better app experience. Finally, you’ll integrate Sentry into our error boundary for realtime error reporting. The only prerequisite is that you have some familiarity with React class components. Let’s dig in!

Factories are a faster way to create new database records., A fixture is a state of a set or collection of objects that serve as a baseline for running tests, and a serializer is responsible for transforming the response. In this second part of the Mirage JS Deep Dive series, Kelvin Omereshone will be looking at Mirage JS’ Factories, Fixtures, and Serializers. You’ll see how they enable rapid API mocking using Mirage.
