How to unit test with click-mock?

[Andrei Ionescu]

I red the available documentation but it's still not clear to me how to 
unit test using click-mock properly :(.

For the beginning, my application is using a ServletContextListener to 
do some stuff (like init embedded database, prepare some files, etc.) , 
but I don't seem to get it how to unit test if that listener is doing 
it's job correctly :(.
How do I simulate with click-mock that what a servlet container would 
do? to see if the ServletContextListener works as it should?

many thanks,
Andrei.
