This is probably the wrong approach to do what you have in mind.

No.  But actually it is not needed either.  Use itest instead.

Ditto.

Have a look at itest; if you still make no progress then please
describe what you actually want to do, so we can show you how to do it
efficiently - without need to modify code.
