 Automation {#automation}
 ==========
-This section extends the [=automation=] section defined in the Generic Sensor API [[GENERIC-SENSOR]]
-to provide mocking information about the ambient light levels for the purposes of testing a user agent's
-implementation of [=Ambient Light Sensor=].
 
+This section extends [[GENERIC-SENSOR#automation]] by providing [=Ambient Light Sensor=]-specific virtual sensor metadata.
 
-<h3 id="mock-ambient-light-sensor-type">Mock Sensor Type</h3>
-
-The {{AmbientLightSensor}} class has an associated [=mock sensor type=] which is
-<a for="MockSensorType" enum-value>"ambient-light"</a>, its [=mock sensor reading values=]
-dictionary is defined as follows:
+<div algorithm>
+The <dfn>illuminance reading parsing algorithm</dfn>, given a JSON {{Object}} |parameters|, must return the result of invoking [=parse single-value number reading=] with |parameters| and "`illuminance`".
+</div>
 
-<pre class="idl">
-  dictionary AmbientLightReadingValues {
-    required double? illuminance;
-  };
-</pre>
+The [=per-type virtual sensor metadata=] [=map=] must have the following [=map/entry=]:
+: [=map/key=]
+:: "`ambient-light`"
+: [=map/value=]
+:: A [=virtual sensor metadata=] whose [=virtual sensor metadata/virtual sensor type=] is [=Ambient Light Sensor=] and [=reading parsing algorithm=] is [=illuminance reading parsing algorithm=].
