Method and system for predicting memory leaks from unit testing

A method for predicting memory leak in a computer program. The method includes acquiring a reference to a tested unit included in the computer program for preventing static data objects from being deallocated; repeatedly executing the tested unit for more than once; tracking which objects in the tested unit are allocated in a corresponding executing time; performing garbage collection; tracking which objects are deallocated during the garbage collection; comparing the object allocations to the object deallocations; and determining if every execution of the tested unit allocates memory that cannot be deallocated.
