Does the function ClassificationTree.fit already perform pruning according to a complexity criterion?

I want to grow a classification tree and determine the best level of complexity. Whenever I grow a tree with the default setting, I end up with a tree of reasonable size. In contrary, if grow a max tree setting minparent to 1 I end up with pretty large trees. If I am pruning this tree back using test() to determine the best level, and prune () to execute the pruning I always end up with the same tree which I would have gotten by just using the default function. Is this always the case? Does ClassificationTree.fit already perform the same steps automatically?
