Someone shared this result with you. It was made with Mic, Camera and Keyboard Test, free on VISU, no sign-up.
Speak or clap: the bar should move. If it stays flat, pick another microphone.
You should see yourself. The image is mirrored, like a mirror.
Press keys: each one lights up and stays lit. Keys that never light did not reach the browser.
Nothing is recorded, saved or sent. The browser asks for permission, and the test stops when you switch tabs or leave.

Examples
Before a video call
The mic bar moves when you talk and the camera shows 1280 × 720: you are ready.
A sticky key
You press every letter and the E never lights up: the key needs cleaning or repair.
Questions
Is my voice or image recorded?
No. The page only reads the live signal to draw the bar and the preview. Nothing is recorded, stored or sent.
Why does the browser ask for permission?
Browsers never let a page use the mic or camera without asking. If you said no by mistake, allow it in the address bar.
The mic bar does not move. What now?
Pick another microphone in the list, check that it is not muted, and that no other app is using it.
Does the keyboard test work with any layout?
Yes. It reads the physical key, so it works with QWERTY, ABNT and other layouts. Some keys, like the Windows key, may be taken by the system first.
Does it work on a phone?
The mic and camera tests do. The keyboard test needs a physical keyboard.
