How can I use advanced mocking in Jest with Vue 3?

You can use Jest's mocking capabilities to create mock functions, modules, and components in Vue 3. Would you like a specific example?

Yes, please provide an example of mocking a Vue component.

Sure! You can use jest.mock() to mock a component. For instance, if you have a component called MyComponent, you can do:

jest.mock('./MyComponent.vue', () => ({
  template: '<div></div>',
  methods: { myMethod: jest.fn() }
}));

What about mocking Vuex store in my tests?

To mock a Vuex store, you can create a mock store using vuex-mock-store. Here's a simple setup:

import { createStore } from 'vuex';
const store = createStore({
  state: { count: 0 },
  mutations: { increment: state => state.count++ }
});

Can I mock API calls in my Vue 3 tests?

Absolutely! You can use jest.mock() to mock API calls. For example:

import axios from 'axios';
jest.mock('axios');
axios.get.mockResolvedValue({ data: { /* mock data */ } });
