Abstract

The article presents the first component of a new approach for testing distributed object-oriented applications called TestByRep which is based on the concept of replication of object states. The paper describes key ideas in TestByRep like: hash clocks for ordering events in distributed object-oriented systems with the unknown number of objects, the E-path for representing the execution of the method, construction of the E-tree for determining states of objects involved in a remote method call and introduces the recovery condition in order to assure that the determined state is consistent.
