KeyboardTest is a simple yet effective software application which allows users to perform benchmarks on their keyboards, in order to check keys accuracy, among others. It offers support for a few keyboard models, such as Cherry French, Dell Desktop, Lenovo G575 and Storm 2210 Standard.
The interface of the utility consists of a single window that shows an image of your keyboard, depending on the type selected from a list. Testing the device is done in the simplest way possible, as you type keys and find out the depress and lag time, typed characters per second, last key down and key up, along with the Windows and BIOS key code (after matching the key code to one of these options). KeyboardTest also supports the mouse buttons and can test the mouse for unwanted drift; all you have to do is hold the device still for 10 seconds. Furthermore, you can benchmark the movement by moving the mouse to all corners of the screen, and find out screen X and Y coordinates and relative hardware X and Y changes. Last but not least, the tool lets you test the LEDs.
Unfortunately, the app does not provide an option for logging all this information to file or printing it for further scrutiny. Furthermore, we would have liked to see coverage for additional keyboard models.
KeyboardTest has a minimal impact on the system performance, since it runs on a very low quantity of CPU and RAM. It is very responsive to commands and completes a keyboard test rapidly and error-free. The app did not hang, crash or pop up error dialogs. Considering the overall simplicity of its GUI and intuitive options, KeyboardTest shouldn't be difficult to learn, even if we're talking about less experienced users.
