What are some tips for testing Redux applications?

When testing Redux applications, focus on testing reducers, actions, and components separately. Use libraries like Jest and React Testing Library.

How do I test asynchronous actions in Redux?

For asynchronous actions, you can use middleware like Redux Thunk or Redux Saga. Test them by mocking API calls and checking the dispatched actions.

Can you give an example of a test case for a Redux reducer?

Sure! A simple test case for a reducer could look like this: expect(reducer(initialState, { type: 'ADD_TODO', payload: newTodo })).toEqual(updatedState);

What tools do you recommend for testing Redux?

I recommend using Jest for unit tests, React Testing Library for component tests, and Redux Mock Store for testing Redux-specific logic.
