[pygame] How to send a keyboard event ?

["PierreLafrance1@xxxxxxxxxxxx" <PierreLafrance1@xxxxxxxxxxxx>]

Hi
I have a simple question : I want to create a class that generates keyboard
event to test my application.
Ex : I want a method to send this :
event.type == KEYDOWN and event.key == K_KP_PLUS:

Any pointers to help me doing this ?
Thanks
