@Josh-Walker-GM Is it worth adding a mini guide / tutorial on how to create a e2e test? -- Or maybe this is better as a blog post that we link out to?

[Josh-Walker-GM]

Yeah sounds like a great idea! A reference, a tutorial which adds some more context/example around the usage and then getting some blog content out of that tutorial example. Sounds win-win.
