Abstract
A computerized method receives an implementation comprising a modifier method and an observer method of a class implementing an abstract data type. The method symbolically executes the modifier method to obtain constrained states, and applies the observer method in constrained states to obtain specialized axioms. The method then creates a specification from the obtained specialized axioms based on generalizing, merging and simplifying the specialized axioms.
