  A mock store for testing Redux async action creators and middleware.

  

Redux Toolkit includes a configureStore method that allows you to preload it with state. The createStore method in redux includes this option as well. In the old days I would rely on tools like redux mock store to generate redux stores for testing, but you don't need it. You can generate a store for your tests that includes exactly the same reducers as your app, but also comes pre-loaded with whatever state you need for your tests.

The next utility that you'll need is a way to render your components with state and context. For my tests I'm usually using React Testing Library, but the same approach works fine if you're using enzyme.
