How do I test Redux Saga effects?

To test Redux Saga effects, you can use libraries like Jest and redux-saga-test-plan. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

import { runSaga } from 'redux-saga';
import { mySaga } from './sagas';
import { myApi } from './api';

const dispatchedActions = [];

const fakeStore = {
  getState: () => ({ /* initial state */ }),
  dispatch: (action) => dispatchedActions.push(action),
};

await runSaga(fakeStore, mySaga).toPromise();

console.log(dispatchedActions);

What are some common pitfalls when testing Redux Saga?

Common pitfalls include not properly mocking API calls, failing to handle asynchronous actions, and not testing all possible outcomes.
