A quick method for testing hooks with react-testing-library

hooktester.js

import React from 'react'
import { render } from 'react-testing-library'

export default hookfn => {
	const Comp = ({ children, args }) => children(hookfn(...args))

	const setup = (...args) => {
		let output = {}

		render(
			<Comp args={args}>
				{val => {
					output = Object.assign(output, val)
					return null
				}}
			</Comp>
		)

		return output
	}

	return setup
}
