How should I test a progress bar before submitting?
Test setting to 0%, 50%, 100%. Test auto-increment reaches 100 and stops. Test values above 100 are clamped to 100. Test values below 0 are clamped to 0. Test that the animation is smooth (no jerky movements).

Core (container, fill, CSS transition, clamp 0-100, percentage display), advanced (auto-increment, color-based, circular, stripes, buttons), accessibility (role, aria-valuenow, aria-label), CSS (gradient, border-radius, transition, responsive), and testing (0%, 50%, 100%, clamping, smooth animation).
A container div, a fill div whose width is set by JavaScript, CSS transition for smooth animation, clamping to 0-100, and a percentage display. These are the minimum required features.
Auto-increment (setInterval), color based on progress (red/yellow/green), circular progress bar (SVG), striped animation for indeterminate, and buttons to increase/decrease/reset. These show depth.
