Rather than use our own custom expect library, we can use expect from npm [1], which has an API almost identical to the one Puppeteer has, but with more options, better diffing, and is used by many in the community as it's the default assertions library that comes with Jest. It's also thoroughly documented [2]. [1]: https://www.npmjs.com/package/expect [2]: https://jestjs.io/docs/en/expect
