01
What the mouse button test checks
| Check | How it is measured | Fails when |
|---|---|---|
| Primary signal | Browser button indexes normally identify left as 0, middle as 1 and right as 2. Back and forward commonly use 3 and 4 when the browser exposes them. | A required input or response never reaches the page. |
| Comparison value | A complete press needs both pointerdown and pointerup. Releasing outside the stage is watched at window level so the pressed state can still be cleared. | Repeated samples remain incomplete or disagree under the same conditions. |
| Browser boundary | Back and forward buttons may remain reserved for browser navigation. A silent side button in this page is not enough to prove a switch failure. | The requested conclusion depends on information a browser cannot expose. |
How to run the mouse button test
- Prepare the device and focus the test stage.
- Complete every prompted direction, control or channel.
- Finish the run, read the verdict and repeat once under the same conditions.
If something failed
For the mouse button test, keep the tab visible, use the same duration and change one device or system setting at a time. A third run can separate a repeatable pattern from scheduling noise.
Reset the mouse button test counters, exercise each named control separately and watch the live readout. Test another port or application if the same control remains silent.
02
How to read the result
What the result can establish
Back and forward buttons may remain reserved for browser navigation. A silent side button in this page is not enough to prove a switch failure. A pass confirms that the required signals arrived during this sample. A warning identifies an uneven or incomplete pattern that deserves another controlled run. A failure names the missing or abnormal signal and gives a direct action. An inconclusive result means the run did not collect enough valid input to support a decision.

A complete press needs both pointerdown and pointerup. Releasing outside the stage is watched at window level so the pressed state can still be cleared. Use the specification table to see which browser signal is counted and what makes the check incomplete. Finish the run only after both directions, channels, controls or phases named by the instrument have been exercised. Reset before changing devices so old events do not enter the next comparison.

Measurement limits
Browser button indexes normally identify left as 0, middle as 1 and right as 2. Back and forward commonly use 3 and 4 when the browser exposes them. The page does not upload hardware streams, recordings, device labels or measured values. Any supported history remains in this browser. Clearing site storage removes that local history. The test cannot inspect physical wear, electrical faults, driver internals or manufacturer calibration data. Read the how to test mouse when you need a repeatable diagnostic sequence.
Back and forward buttons may remain reserved for browser navigation. A silent side button in this page is not enough to prove a switch failure. Repeatability matters more than a single attractive number. Use the same browser window, foreground state, power mode, connection and physical method. If two runs disagree, collect a third run and use the middle pattern rather than selecting the result you expected. Read the how to test mouse when you need a repeatable diagnostic sequence.
