How Desktop, Tablet, and Mobile Browser Evidence Is Captured

Responsive browser evidence lets QCUL compare the updated laboratory at desktop, tablet, and mobile-style viewport sizes so obvious layout/resource failures are easier to notice.

Why multiple viewports help

• Navigation or controls may work at desktop width but collapse incorrectly on mobile.
• Conditional assets/scripts can load differently at smaller breakpoints.
• Administrator/frontend template CSS regressions can appear only in certain viewport ranges.

What to review

Look for clipped controls, overlapping content, missing menus, unusable dialogs/forms, horizontal overflow, and resources that fail only in one viewport. A screenshot is most useful when compared with expected production behavior and the surrounding console/resource evidence.

Do not confuse viewport evidence with device testing

A resized browser is not a full substitute for every physical browser/device combination. If the update affects a mobile-critical workflow, test that workflow on representative real devices/browsers before production.

Read evidence in context

Use How Desktop, Tablet, and Mobile Browser Evidence Is Captured together with the other evidence for the same tested item. A version check, route check, log message, screenshot, or file/database diff is strongest when it agrees with the surrounding evidence and your own reproduction in the private laboratory; no single signal should be treated as universal compatibility proof.
