How can I test the Vuex store in a Nuxt.js application?

How can I test the Vuex store in a Nuxt.js application?

You can use libraries like Jest or Mocha along with Vue Test Utils to test your Vuex store.

Can you give me an example of a test case for a Vuex action?

Sure! Here's a simple example:

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

const store = createStore({
  actions
});

test('increment action', () => {
  const commit = jest.fn();
  actions.increment({ commit });
  expect(commit).toHaveBeenCalledWith('INCREMENT');
});

What about testing mutations?

For mutations, you can directly test them by passing the state and payload. Here's an example:

import mutations from './mutations';

const state = { count: 0 };

mutations.INCREMENT(state);
expect(state.count).toBe(1);

Are there any best practices for testing Vuex?

Yes! Keep your tests isolated, use descriptive names, and test both the state and actions/mutations.
