Method for validation and modification of device state transitions for an aerosol generation device

A method for testing aerosol provision devices, the method comprising performing a functional state transition test of a power unit, the functional state transition test of the power unit comprising:

• extracting a unique identifier from the power unit of an aerosol provision device responsive to operable coupling of the power unit to a test fixture;
• determining a transition code based on the unique identifier;
• providing the transition code to the power unit via the test fixture to transition the power unit from an initial state to a transitioned state;
• and
• transitioning the power unit to the initial state,
• the method further comprising performing a functional state transition test of a second power unit, the functional state transition test of the second power unit comprising:
• detecting insertion of the second power unit into a second test module of the test fixture;
• extracting a second unique identifier from the second power unit responsive to operable coupling of the second power unit to the test fixture;
• determining a second transition code based on the second unique identifier;
• providing the second transition code to the second power unit via the test fixture to transition the second power unit from the initial state to the transitioned state;
• and
• transitioning the second power unit to the initial state,
• wherein a first optical transmitter provides the transition code to the power unit, and a second optical transmitter provides the second transition code to the second power unit, and
• wherein the first and second optical transmitters are each independently controlled to provide different optical transition signals at respective different times based on the first and second transition codes, respectively.

A method for testing aerosol provision devices, the method comprising:

• performing a first functional state transition test of a first power unit of a first aerosol provision device, the functional state transition test of the first power unit comprising:
• extracting a unique identifier from the first power unit of the first aerosol provision device automatically responsive to detecting the first power unit in a first cavity of a test fixture;
• determining a transition code based on the unique identifier automatically responsive to extracting the unique identifier from the first power unit;
• providing the transition code to the first power unit via the test fixture to transition the first power unit from an initial state to a transitioned state;
• and
• transitioning the first power unit to the initial state responsive to an indication of transitioning of the first power unit from the initial state to the transitioned state, and performing a second functional state transition test of a second power unit of a second aerosol provision device inserted into a second cavity of the test fixture while performing the first functional state transition test is also in progress.
