How can I test Vue components effectively?

You can use tools like Vue Test Utils and Jest to test your Vue components. Would you like a brief overview of how to set them up?

Yes, please explain how to set up Vue Test Utils.

To set up Vue Test Utils, first install it via npm: npm install --save-dev @vue/test-utils. Then, you can create a test file and import the component you want to test.

What about Jest? How do I integrate it with Vue?

You can integrate Jest by installing it with npm install --save-dev jest. Then, configure your package.json to include a test script that runs Jest.

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

Sure! Here's a simple test case:

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

test('renders correctly', () => {
  const wrapper = mount(MyComponent);
  expect(wrapper.text()).toContain('Hello World');
});
