P type Mosfet Testing Circuit.
That seems to cover it!
I drew p and N types and including the voltages and the different Vf of led, it's more easy to do a test for a newbie, but those were not cover all of them, they still have some others as 2V/3mm, 3V/3mm, but this just a basic testing circuit, if you thought any ideas then I can add in.
Might be too complicated for a newbie, but if you put a second LED across the existing LED, but with the opposite polarity, your text fixture could switch between testing P-channel and N-channel FETs by simply reversing the power supply connection.
