1. A method for locating testable objects in a functional testing tool, the method comprising the steps of: comparing object properties for a mapped testable object comprising a graphical user interface (GUI) object rendered in a GUI provided by a display of a computer that is testable, to object properties for each of a set of candidate testable objects organized in a hierarchy; computing in the computer an anchor object in the hierarchy; and, determining a best matching candidate testable object for the mapped testable object without requiring an exact match of the object properties while constraining the comparing and determining steps with respect to the anchor object.
