How can I mock Vuex in my unit tests?

You can use libraries like Vue Test Utils along with Jest to mock Vuex. Would you like a code example?

Yes, please provide a code example.

Sure! Here's a simple example:

import { createStore } from 'vuex';
import { mount } from '@vue/test-utils';
import MyComponent from '@/components/MyComponent.vue';

const store = createStore({
  state: { count: 0 },
  mutations: {
    increment(state) {
      state.count++;
    }
  }
});

const wrapper = mount(MyComponent, { store });

This sets up a basic Vuex store for your component.

How do I test actions and mutations?

You can test mutations by directly calling them and checking the state. For actions, you can dispatch them and then verify the state changes.
