Browser

The Browser card (on the Settings tab) controls browser-level behaviour and how the page is analysed. It has two sub-sections — Browser Behavior and Page Analysis.

Browser Behavior

FieldDescriptionDefault
Disable CORS Checks (Cross Origin Resource Sharing)Disable browser CORS checks for the application — useful for internal apps that can't be reached through normal cross-origin rules during testing.off
Send authorization header (Basic Auth) only for start domainIf you log in via browser Basic Auth, restrict that header to the start domain rather than sending it to every frame and request. Recommended whenever the test touches domains that aren't yours.off (sent to all frames)
Reuse browser cache between test executionsKeep the browser cache populated across runs. Useful for performance tests where a warm cache reflects real-world behaviour.off
Override page font familyForce a specific font during the test (OCR-A, Noto Sans / Mono, DejaVu Sans / Mono, Liberation Sans / Mono, …). Useful for screenshot-based assertions and OCR comparisons.Default (no override)

Page Analysis

These settings help the AI focus on what matters by hiding noise on the page. All list fields accept comma- or semicolon-separated values.

tip

Hiding non-relevant elements is especially useful when the page contains dynamic attributes or animations that change with every load — they hurt the runner's cache hit ratio if they are not ignored.

FieldDescription
Ignore DOM tagsDOM tags to drop from element analysis. Example: noscript, script, style.
Ignore DOM attributesAttribute names to drop. Example: data-qa, data-testid.
Ignore DOM classesCSS classes to drop.
CSS selectors to hideSemicolon-separated CSS selectors of elements to hide visually (cookie banners, support chat widgets, …).
Do not wait for animationsIgnore animations when judging whether the page is idle — useful for pages with permanently looping background animation.
CSS selectors to ignore animationsVisible when Do not wait for animations is on. Restricts the rule to specific elements via semicolon-separated CSS selectors.
