How can I use custom render functions in Vue Test Utils?

You can create custom render functions in Vue Test Utils to customize how components are rendered during tests. This allows you to provide specific props, slots, or even mock child components.

Can you show me an example of a custom render function?

Sure! Here's a simple example:

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

const customRender = (props) => {
  return render(MyComponent, { props });
};

// Usage
customRender({ myProp: 'value' });

What are the benefits of using custom render functions?

Custom render functions allow for greater flexibility in testing by enabling you to easily modify the component's context, making it easier to test various scenarios.

Are there any limitations I should be aware of?

Yes, while custom render functions are powerful, they can add complexity to your tests. It's important to ensure that they don't obscure the component's behavior or make tests harder to understand.
