-to provide mocking information about the [=geolocation=] of the hosting device for the purposes of
-testing a user agent's implementation of {{GeolocationSensor}} API.

+This section extends [[GENERIC-SENSOR#automation]] by providing [=Geolocation Sensor=]-specific virtual sensor metadata.
 
-The {{GeolocationSensor}} class has an associated [=mock sensor type=] which is
-<a for="MockSensorType" enum-value>"geolocation"</a>, its [=mock sensor reading values=]
