Yes, so are you suggesting that I create an instance of my S4 class in order to
test my function.
My understanding is that ideally the test should not depend on any code besides
the one that I am testing.
I just thought that you could perhaps define a mock class so that I would not
need to invoke my external constructor function, hence making this test focus
exclusively on the function that I am trying to test. Is it possible to do
this in R?
