JavaScript testing utilities for React
At this point, it should be clear how to test basic components with Jest and Mocha and what the pros and cons are of both.
You have also learned what the TestUtils are and the difference between Shallow rendering and full DOM Rendering.
You may have noticed that the TestUtils, even if they provide a useful tool to help testing components, are verbose and sometimes it is not easy to find the right approach to get the reference to the elements and their properties.
That is the reason why the developers at AirBnb decided to create Enzyme, a tool built on top of the TestUtils that makes it easy to manipulate the rendered components.
The API is nicer, similar to jQuery, and it provides many useful utilities to interact with components, their states, and their properties.
Let's see what it means to convert our Jest tests to use Enzyme instead of the TestUtils.
So, please go back to the Jest
project we previously created and install enzyme
:
npm install --save-dev...
