Hierarchical data processor tester

A system comprising:

• one or more processors configured to implement a data processor test system that implements a hierarchical set of similarity operators to test a data processor;
• wherein the data processor test system is configured to:
• process a plurality of records through a data processor under test (DPUT), each record containing predetermined input test data and predetermined output test data;
• for each record, process actual output data from the DPUT based on the predetermined input test data from each record and the predetermined output test data through at least one of the plurality of similarity operators until a similarity operator indicates a match between the predetermined output test data and the actual output data from the DPUT;
• for each record, compute a confidence score based on an order of the similarity operator that indicated the match;
• based on the confidence scores, activate the DPUT for use by non-test data.

A computer program product for testing a data processor, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processing resource to cause the processing resource to:

• specify an order for a plurality of similarity operators in a set of similarity operators;
• process predetermined input test data through a data processor under test (DPUT) to produce corresponding DPUT actual test output data;
• process the DPUT actual test output data and the predetermined output test data in the set of similarity operators in the specified order until one of the similarity operators indicates a match between the DPUT actual test output data and the predetermined output test data;
• determine a highest order similarity operator that indicates a match between the DPUT output data and the predetermined output test data;
• and
• compute a confidence score based on the determined highest order.
