How can I set up Mocha testing for Vuex with vue-cli-plugin?

To set up Mocha testing for Vuex using vue-cli-plugin, first install the plugin with npm or yarn.

What commands do I need to run to install the plugin?

You can run vue add mocha to install the Mocha plugin for your Vue project.

Are there any specific configurations I need to do after installation?

Yes, you may need to configure your mocha.opts file to include your test files and set up any necessary Vuex store mocks.

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

Sure! Here's a simple test case:

import { createStore } from 'vuex';
import { expect } from 'chai';

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

describe('Vuex Store', () => {
  it('increments count', () => {
    store.commit('increment');
    expect(store.state.count).to.equal(1);
  });
});
