Mouse Tester

Mouse Tester - Test Your Mouse Online

A comprehensive online mouse testing tool that helps you check if your mouse is working correctly. Test all mouse buttons (left, middle, right, and extra buttons), scroll wheel functionality, cursor movement, tracking accuracy, and more. Perfect for diagnosing mouse issues, checking new mice, or verifying mouse settings.

How do I test my mouse?

Testing your mouse is simple:

1. Move your mouse in the test area to check cursor tracking
2. Click each button (left, middle, right) to verify they work
3. Use your scroll wheel to test scrolling up and down
4. Try double-clicking to test double-click detection
5. Check the event log for real-time feedback
6. View statistics like total clicks and distance moved

The tool will display coordinates, button states, and log all mouse events in real-time.

What can I test with this tool?

This mouse tester allows you to check:

- Left, middle, and right mouse buttons
- Extra mouse buttons (Button 4 and Button 5)
- Mouse cursor position and coordinates
- Scroll wheel functionality and direction
- Double-click detection
- Mouse movement tracking
- Total distance moved
- Click counts for each button
- Response time and accuracy

All tests happen in real-time with visual and numerical feedback.

Why test mouse buttons?

Testing your mouse buttons is useful when:

- You suspect a button isn't working properly
- Clicks aren't registering consistently
- You get a new mouse and want to verify it works
- Double-clicks happen when you single-click (or vice versa)
- You're troubleshooting gaming or productivity issues
- You want to check if extra buttons are recognized
- Testing before or after driver updates

This tool helps identify hardware issues, driver problems, or configuration errors.

What are Mouse Coordinates?

The tool displays two types of coordinates:

- Position X/Y: Mouse position relative to the test area (0,0 is top-left)
- Client X/Y: Mouse position relative to the entire browser window

These coordinates help verify:
- Cursor tracking accuracy
- Mouse sensitivity
- Diagonal movement smoothness
- Position reporting correctness

Coordinates update in real-time as you move the mouse.

How does scroll wheel testing work?

The scroll wheel test shows:

- Scroll Direction: Up or Down based on wheel movement
- Scroll Delta: How much you scrolled (magnitude)
- Scroll Count: Total number of scroll events

This helps identify:
- If the scroll wheel is working at all
- Scroll direction correctness
- Scroll sensitivity and smoothness
- Inconsistent scrolling behavior

Try scrolling slowly and quickly to test different speeds.

What is the Event Log?

The Event Log displays every mouse action in real-time:

- mousemove: Cursor movement (blue)
- mousedown: Button pressed (green)
- mouseup: Button released (red)
- wheel: Scroll events (yellow)
- dblclick: Double-click detected (purple)

Each event shows:
- Event type and details
- Timestamp (precise to milliseconds)
- Button or coordinates involved

The log helps diagnose timing issues, missed clicks, or erratic behavior.

Is this tool accurate?

Yes, this mouse tester is highly accurate:

- Uses native browser mouse events (same as games and apps)
- Millisecond-precision timing for events
- Pixel-accurate coordinate tracking
- Real-time button state detection
- Accurate scroll delta measurement

The tool reports exactly what your browser receives from the operating system, making it an accurate diagnostic tool for hardware and driver issues.

Does this work on all devices?

This mouse tester works on:

- Desktop computers with mice
- Laptops with trackpads or external mice
- Tablets with mouse support (iPad with Magic Mouse, etc.)
- Any device where a cursor can be controlled

Note: Touch-only devices (phones without mouse support) won't work with this tool since it specifically tests mouse hardware. For trackpads, the tool will track finger movements as cursor movement.
