Follow the steps, click left/middle/right, and scroll up/down on the illustration. Once all five actions are detected, your mouse passes.
Press left, middle (wheel click), and right. Each card should highlight and count your presses.
Hover the illustration, scroll the wheel up once, then down once. Both arrows should light up.
Score reaches 100% when all five actions are detected. Use reset to run it again.
Interact directly with the mouse illustration. Each action lights up and counts toward your score.
A mouse test verifies all your mouse functions are working: left, right, middle button clicks, and scroll wheel movement in both directions. It detects common issues like double-clicking bugs and scroll wheel skipping. Useful for troubleshooting, testing mice before purchase, or diagnosing hardware issues. This browser-based tester runs instantly with no installation required.
Use this tool to verify every button and scroll action.
Our mouse tester uses JavaScript event listeners to detect mouse button presses (left, right, middle) and scroll wheel movements. When you click or scroll, the browser fires events that we capture and visualize in real-time. We track each button's state, count clicks, measure scroll direction and speed, and detect potential double-click issues. All processing happens locally in your browser with no data sent to servers.
This browser-based test accurately detects standard mouse buttons (left, right, middle) and scroll wheel events. However, there are limitations: Side buttons and extra gaming buttons may not be detected by browsers. DPI and sensor accuracy cannot be tested through web events. Some gaming mice with proprietary drivers may behave differently. For comprehensive mouse diagnostics, manufacturer software may be needed.
Buttons should light up immediately when pressed and return to normal on release. Delayed or stuck highlights may indicate switch issues or driver problems.
If single clicks register as double-clicks, your mouse likely has switch wear. This is a common issue in older mice and may require repair or replacement.
Scroll should register smoothly in both directions. Skipping, reversing, or erratic behavior indicates encoder issues or debris inside the scroll mechanism.

Methodology: Our testing methodology uses standard Web APIs (MouseEvent, WheelEvent) supported by all modern browsers. Tests are designed for accuracy and repeatability.
About: HardwareTest provides free, privacy-first hardware diagnostics. All tests run entirely in your browser with no data collection.
Disclaimer: This tool tests standard mouse functions only. Side buttons and advanced features may require manufacturer software. For warranty claims, consult your mouse manufacturer.
Tips for clicks, scroll wheels, and performance.
A data-backed look at 100 gaming mice across 125Hz to 8000Hz, with stability notes, real-world limits, and how to compare your setup using our mouse polling rate test.
A 2026 roundup of hardware testing tools, from browser-based no-install checks for mice and screens to GPU stress tests and system monitoring.
Web-based mouse polling tests measure browser-delivered pointer event frequency, not raw USB polling. Learn why ~125Hz appears, why high polling rates are indistinguishable on the web, and how to interpret results.
Learn the difference between CPS and CPM, what counts as a good click speed, and whether 10-second or 30-second tests are more accurate. Then run our free click speed test and share your results.
Learn what mouse polling rate (Hz) means, the real difference between 125/500/1000Hz, and how to test your mouse polling rate online using our browser-based distribution and stability checker.
Check if your gaming keyboard truly runs at 1000Hz, 500Hz, or 125Hz with our free online polling rate tester and real-time Peak Hz dashboard.
