Feature: A presence Light

A presence Light which is by default off.

When forced on by the user can be turned off by the system if nobody is in the room.

You could know that nobody is in the room when, as an example, the room alarm sensors are presence.

Other events could be used for the same purpose.

Scenario Outline: The Light does not react to alarm presence events from an unforced state

Given A light.presence.Appliance appliance

And the appliance has an internal event.presence state at <presence>

And the appliance has an internal appliance.light.event.forced state at Not

And it’s calculated state is <from_state>

When it receives a new event <event>

Then the appliance new state is <to_state>

Examples:

presence	from_state	event	to_state
Off	light.presence.state.off	event.presence.Event.Off	light.presence.state.off
Off	light.presence.state.off	event.presence.Event.On	light.presence.state.off
On	light.presence.state.off	event.presence.Event.Off	light.presence.state.off
On	light.presence.state.off	event.presence.Event.On	light.presence.state.off

Scenario Outline: The Light react to forced on events

Given A light.presence.Appliance appliance

And the appliance has an internal event.presence state at <presence>

And the appliance has an internal appliance.light.event.forced state at Not

And it’s calculated state is <from_state>

When it receives a new event <event>

Then the appliance new state is <to_state>

Examples:

presence	from_state	event	to_state
Off	light.presence.state.off	appliance.light.event.forced.Event.Off	light.presence.state.off
Off	light.presence.state.off	appliance.light.event.forced.Event.On	light.presence.state.forced.on

Scenario Outline: The Light react to forced on/off events from a forced on state

Given A light.presence.Appliance appliance

And the appliance has an internal event.presence state at <presence>

And the appliance has an internal appliance.light.event.forced state at On

And it’s calculated state is <from_state>

When it receives a new event <event>

Then the appliance new state is <to_state>

Examples:

presence	from_state	event	to_state
Off	light.presence.state.forced.on	appliance.light.event.forced.Event.Off	light.presence.state.off
Off	light.presence.state.forced.on	appliance.light.event.forced.Event.On	light.presence.state.forced.on
On	light.presence.state.forced.on	appliance.light.event.forced.Event.Off	light.presence.state.off
On	light.presence.state.forced.on	appliance.light.event.forced.Event.On	light.presence.state.forced.on

Scenario Outline: The Light react to alarm presence events from a forced on state

Given A light.presence.Appliance appliance

And the appliance has an internal event.presence state at <presence>

And the appliance has an internal appliance.light.event.forced state at On

And it’s calculated state is <from_state>

When it receives a new event <event>

Then the appliance new state is <to_state>

Examples:

presence	from_state	event	to_state
Off	light.presence.state.forced.on	event.presence.Event.Off	light.presence.state.off
Off	light.presence.state.forced.on	event.presence.Event.On	light.presence.state.forced.on
On	light.presence.state.forced.on	event.presence.Event.Off	light.presence.state.off
On	light.presence.state.forced.on	event.presence.Event.On	light.presence.state.forced.on

Scenario Outline: The Light shows its is_on property

Given A light.presence.Appliance appliance

And the appliance has an internal event.presence state at <presence>

And the appliance has an internal appliance.light.event.forced state at <forced>

And it’s calculated state is <state>

When it’s asked for its state property is_on

Then the response is <response>

Examples:

presence	forced	state	response
On	Not	light.presence.state.off	False
On	On	light.presence.state.forced.on	True
