Jest is a Javascript Testing Framework. It focuses on simplicity according to their webpage. Jest integrates well with most popular frameworks and libraries. In this article we will create a simple Redux Store Middleware inside a WordPress Installation. Then write tests in Jest to test the implementation.

First, a WordPress REST API should be created to handle requests from the app. Then a Redux Store should be created using Redux Toolkit. We can create a redux store without Redux Toolkit. But we have to use a lot of boilerplate code. Middleware can be used to intercept the dispatched actions before reaching the store. Middleware can also dispatch additional actions if necessary. Let’s create 3 simple middleware. Finally, let’s write some tests with Jest for the store implementation.

The plugin initially released on November 03, 2013. Almost 8 years back. After few years, the plugin was closed due to some issues in the code. The code was fixed and submitted for a review.

One reason for the closure of the plugin was that all code should be compatible with GPL to be included in WordPress directory. The license under which the WordPress software is released is the GPLv2 (or later) from the Free Software Foundation. One of the included libraries was not GPL compatible. So the library was replaced with Chart JS which is fully compatible with GPL.

Now the plugin is listed again in the Official WordPress Plugin Repository.
