How do I test Vuex actions in my Vue.js application?

To test Vuex actions, you can use a testing framework like Jest along with Vue Test Utils. Start by mocking the store.

Can you show me a simple example of testing a Vuex action?

Sure! Here's a basic example:

import { createStore } from 'vuex';
import { myAction } from './actions';

const store = createStore({
  actions: { myAction }
});

test('myAction commits a mutation', async () => {
  const commit = jest.fn();
  await store.dispatch('myAction', { commit });
  expect(commit).toHaveBeenCalledWith('MY_MUTATION');
});

What if my action makes an API call?

In that case, you can mock the API call using libraries like axios-mock-adapter. This allows you to simulate responses.
