Failure rules for bad render results

Fail runs early when the page lands on a login wall, CAPTCHA, missing selector, or other wrong state instead of treating it as a clean result.

Use this when

Login wall instead of the expected page.
Challenge or CAPTCHA before the browser reaches content.
Missing selector that proves the page did not load as expected.

Bad runs should fail early instead of pretending to pass

A blocked page is not a successful page. If the run lands on a login wall, CAPTCHA, challenge screen, missing selector, or the wrong view entirely, the result should fail as a wrong state instead of drifting into normal history as if nothing happened.

That protects both visual baselines and assertion history. Otherwise a broken page can quietly become a new accepted result or trigger pointless review on a screenshot that never reached the real page state.

Where failure rules matter most

These rules matter most on pages where a clean screenshot can be misleading: checkout, sign-up, docs behind edge protections, localized pages, or flows that depend on cookies and waits.

The more context a page needs before it becomes reviewable, the more important it is to fail the run on wrong states instead of letting reviewers guess from the final image.

Add the first rule set before you trust the history

Define the obvious blocked states first: missing selector, login wall, challenge page, or broken flow step. Then add more specific rules only where the page truly needs them.

That keeps the run history honest. The point is not to create a giant rule engine. The point is to stop obviously wrong states from looking like real page results.

Guide questions

Why not just review the screenshot manually?

Because wrong-state screenshots waste review time and can accidentally become accepted history if the failure is not marked clearly.

What should the first failure rules cover?

Start with the states that clearly prove the browser never reached the intended page: login walls, challenge pages, missing selectors, and broken flow steps.
