The easiest browser test is the one that never leaves the browser.

Open a page. Click a button. Check a message.

Real customer journeys are rarely that polite.

A user signs up, receives an email, opens a verification link, enters an SMS code, uploads a file, downloads a CSV, switches between applications, and retries after an expired session. Meanwhile, the test runs against a preview environment whose URL disappears tomorrow.

At that point, the browser driver is no longer the difficult part.
