Testing Redux

Unit testing Redux is a very straightforward process. There are two primary units:

• Reducers are pure functions that lend themselves well to testing.

• Actions trigger changes in a Redux system. There are two broad categories of actions: synchronous (which are quite simple to test) and asynchronous (which are slightly more involved).

The examples below should provide you with a strong foundation for testing Redux applications.
