what's the best tool set to use for testing react components in Deno?

Ideally something very fast for TDD.

I wasn't able to find the answer to your question in the official Deno documentation, as it primarily focuses on Deno-specific features and runtime capabilities. However, when it comes to testing React components in Deno, the ecosystem is still evolving, and there may not be a direct equivalent to some of the React testing tools you might be familiar with from other environments like Node.js. That being said, Deno comes with a built-in test runner that you can use for testing your code. For testing React components, you might need to look into community-driven solutions or consider setting up a custom testing environment that suits your needs for TDD with React in Deno. Please note that this advice is not based on the Deno documentation, and I would recommend double-checking the accuracy of this advice and looking for any community tools or best practices that may have emerged for testing React components in Deno.

This is an example from jest document to test react with node Mainly i am wondering how to get the functionality of tree.props.onMouseEnter()
import renderer from 'react-test-renderer';
import Link from './Link';



it('changes the class when hovered', () => {
const component = renderer.create(
<Link page="http://www.facebook.com">Facebook</Link>,
);
let tree = component.toJSON();
expect(tree).toMatchSnapshot();

// manually trigger the callback
renderer.act(() => {
tree.props.onMouseEnter();
});
// re-rendering
tree = component.toJSON();
expect(tree).toMatchSnapshot();

// manually trigger the callback
renderer.act(() => {
tree.props.onMouseLeave();
});
// re-rendering
tree = component.toJSON();
expect(tree).toMatchSnapshot();
});
import renderer from 'react-test-renderer';
import Link from './Link';
