Browser Flow — Verifying a Journey Still Completes
A browser flow performs a sequence of real actions in a real browser: navigate, fill a field, click, wait for an element, assert that something expected appeared. Because the whole sequence runs in one session, state carries between steps, which is what makes it possible to verify anything behind a login.
Why run it
Because every layer you monitor can be green while the thing users do is broken. The host responds, the database accepts connections, the certificate is valid, the status code is 200 — and the login form returns an error for everyone because a session store is unreachable. Component checks cannot see that; only exercising the path does. For an operator the flow is also the fastest way to confirm a failover or a maintenance window genuinely preserved the user-facing path rather than just the infrastructure underneath it.
Why automate it
Running one by hand is just using the site, and nobody does it at 3am. The value is entirely in unattended repetition against production, because these failures are triggered by production conditions — real data, real third-party dependencies, real certificate state — that no staging environment reproduces. When a step fails, having the failing step identified along with a screenshot of the browser at that moment removes the reproduction phase from the investigation, which is usually the longest part.
What it gives you
Proof that the path a customer takes still works end to end, rather than confirmation that each component is individually healthy. It is the only check here that would catch a broken checkout on a fully green dashboard.
