ABSTRACT:
In a method for assigning test numbers, current testflow context information is maintained during the execution of a testflow. Upon generation of a new test number for a result of a subtest in the testflow, a database of test numbers is indexed using the new test number. If the new test number appears as an entry in the database, a unique identifier associated with the entry is compared to index information comprising 1) an identifier of the subtest, and 2) the current testflow context information. If the unique identifier does not match the index information, a test number collision is identified. Otherwise, the new test number is assigned to the subtest. Other methods and apparatus for identifying test number collisions are also disclosed.
