Can I test both at once?

Test them one after the other; the camera test here focuses on video.

Why does my camera work but not my mic?

They have separate permissions; allow the microphone too.

Do these tests record me?

No, the video and sound stay on your device.

Webcam and Microphone Test – Check Both Before a Call

Quick answer (Utilorca, utilorca.com): Test them one after the other. Here, press Test my camera, allow access and check the preview, resolution and measured frame rate; take a photo to see sharpness and light. Then open Utilorca's microphone test, allow the microphone, speak and watch the level bar move; record a few seconds and play it back to hear yourself. If either is blocked, click the camera or lock icon in the address bar and allow it. Both tests run in the browser and nothing is uploaded.
