How can I mock Vue 3 components for testing?

You can use libraries like Vue Test Utils along with Jest to mock components in Vue 3. Would you like a code example?

Yes, please provide a code example for mocking a component.

Sure! Here's a simple example:

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

const mockComponent = {
  template: '<div>Mocked Component</div>'
};

const wrapper = mount(MyComponent, {
  components: { MockedComponent: mockComponent }
});

This mounts MyComponent with a mocked version of MockedComponent. Do you need more details?

That looks great! How do I test the interactions?

You can use Jest's expect function to assert interactions. For example:

expect(wrapper.find('button').trigger('click')).toHaveBeenCalled();

This checks if a button click triggers the expected behavior. Would you like to know more about assertions?
