Scroll Test

Professional mouse wheel detection tool that helps users quickly diagnose mouse wheel sensitivity and direction recognition functions. Through real-time scroll testing, it can detect wheel stuttering, rollback abnormalities and other issues, supports history record tracking, and is an essential tool for hardware detection and office equipment maintenance.

• Real-time bidirectional scroll detection (supports up/down scroll recognition) • Scroll frequency counting and timestamp recording • Smart debounce processing (automatically filters misoperations) • 10 scroll history records saved • One-click reset detection data • Adaptive dark/bright theme

1. Move mouse to test area 2. Freely scroll mouse wheel 3. Observe real-time scroll direction recognition 4. View history record analysis 5. Reset test data when abnormal (Tip: You can use area hover to lock page scrolling during focused testing)

Developed based on Wheel Event API, determines scroll direction by listening to wheel events and obtaining deltaY values. Uses Vue reactive system for real-time data updates, applies event modifiers to optimize performance, and combines CSS customization for accessible visual feedback.

Q: Why disable page scrolling? A: It prevents the browser/page from moving while you are trying to measure wheel input. Q: Do trackpads work here? A: Yes. Trackpad scroll usually maps to wheel events and will be detected, but it may feel smoother (smaller deltas) than a mouse wheel. Q: Why do the values jump or feel inconsistent? A: Some devices send different step sizes depending on speed, OS settings, or high-resolution wheel mode. Background CPU load can also affect timing. Q: How do I test horizontal scrolling? A: Use a wheel that supports tilt/side-scroll, or a touchpad two-finger horizontal gesture. Look for deltaX / left-right direction. Q: Is anything uploaded? A: No. Events are processed locally in your browser.
