There's nothing hidden, that is the source code.  What UseMethod() does 
depends on the class of x, so you want to look at the cor.test.<class> 
function as well, for the particular class.  Often those methods *are* 
hidden, so you may need something like

getAnywhere(cor.test.default)

to see one.
