Keyboard Tester

The Keyboard Tester provides precise per-key validation for USB keyboards and HID-compliant devices. It maps each physical key to its HID usage and reports per-key pass/fail status, latency, and any anomalies. This is valuable for QA engineers, keyboard manufacturers, and hobbyists who require reliable key-level diagnostics.
How it works conceptually: the tool captures key events from the connected device, compares observed HID codes to expected mappings, and records timing data. It supports live scanning and offline simulation, enabling repeatable results across sessions and configurations.
Unique value: it identifies dead keys, inconsistent debouncing, and ghosting, while offering layout-agnostic testing and exportable results for traceability. Use cases include new keyboard bring-up, production QA, and post-repair validation, with outputs suitable for bug trackers and test dashboards.
Core features and capabilities include per-key results, optional advanced diagnostics, cross-layout support, and cross-platform compatibility. The tool remains data-centric and does not prescribe UI conventions, focusing on accurate measurement, logging, and reproducibility.
