How do I set up integration tests using Jest and Vue Testing Library?

To set up integration tests with Jest and Vue Testing Library, first ensure you have both libraries installed. You can do this by running npm install --save-dev @vue/test-utils jest.

What is the basic structure of an integration test?

A basic integration test typically includes importing the component, rendering it with render() from Vue Testing Library, and then using queries to interact with the component and assertions to verify its behavior.

Can you show me an example of an integration test?

Sure! Here's a simple example:

import { render, screen } from '@testing-library/vue';
import MyComponent from './MyComponent.vue';

test('renders a message', () => {
  render(MyComponent);
  expect(screen.getByText('Hello, World!')).toBeInTheDocument();
});

How do I run the tests after writing them?

You can run your tests by executing the command npm run test in your terminal, assuming you have set up your package.json scripts correctly.
