How do I test Redux actions with Jest?

To test Redux actions with Jest, you can create a test file and import your action creators. Then, use Jest's describe and it functions to structure your tests.

Can you show me an example of a test for a simple action?

Sure! Here's a basic example:

import { myAction } from './actions';

describe('myAction', () => {
  it('should create an action to add a todo', () => {
    const expectedAction = { type: 'ADD_TODO', payload: 'Learn Redux' };
    expect(myAction('Learn Redux')).toEqual(expectedAction);
  });
});

What about testing async actions?

For async actions, you can use middleware like redux-thunk. You would test it by mocking the dispatch function and checking if the correct actions are dispatched.

Are there any best practices for testing Redux?

Yes! Some best practices include testing action creators, reducers, and ensuring your tests are isolated and independent.
