A test point is a location within an electronic circuit that is used to monitor the state of the circuitry or inject test signals.
[1] Test points have three primary uses: Test points can be labeled and may include pins for attachment of alligator clips or may have complete connectors for test clips.
Modern miniature surface-mount electronics often simply have a row of unlabeled, tinned solder pads.
The device is placed into a test fixture that holds the device securely, and a special surface-contact connector plate is pressed down onto the solder pads to connect them all as a group.
