Test selected menus across screen sizes, aspect ratios and lengthened text. Find overflow and off-screen UI, jump to affected objects, and compare screenshots with saved baselines.Verified on Windows in Unity 6000.6.0f1 with URP 17.6.0 and the Built-in Render Pipeline. Requires uGUI 2.6.0, which includes TextMeshPro. Static screen-space Canvas UI previews use a temporary isolated scene and do not capture gameplay, camera stacks or 3D backgrounds. HDRP, custom pipelines, UI Toolkit and world-space source canvases are not supported in version 1.0.Checking every menu manually is repetitive. UI Stress Tester tests selected menus across screen sizes, aspect ratios and artificially lengthened text. It flags text overflow and elements outside the screen, then produces a screenshot report with clickable links to affected objects in Unity.Save your menus and test settings in reusable profiles. Run a resolution and text-length sweep in Edit Mode, inspect each finding, select the source object, fix the layout and run again. Accept a reviewed screenshot baseline to spot visual changes on later runs. Share the complete HTML report folder for offline review with clickable screenshot outlines.The testing workflow includes configurable resolutions, text expansion, hidden-content and viewport handling, exclusions, direct object selection, baseline comparison, difference images and JSON reports. The included inventory demo runs without extra font imports.Requirements: Unity 6.6 and uGUI 2.6.0, including TextMeshPro. Verified on Windows with URP 17.6.0.
