UNIVERSITY OF HERTFORDSHIRE COMPUTER SCIENCE RESEARCH COLLOQUIUM presents "Sorting Sheep from Goats - Automatically Clustering and Classifying Program Failures" Dr. Marc Roper (University of Strathclyde, U.K.) 23 March 2016 (Wednesday) 1 pm - 2 pm Hatfield, College Lane Campus Lecture Theatre LF233 Everyone is Welcome to Attend Refreshments will be available Abstract: In recent years, software testing research has produced notable advances in the area of automated test data generation. It is now possible to take an arbitrary system and automatically generate volumes of high-quality test data. But the problem of checking the correctness or otherwise of the outputs (termed the "oracle problem") still remains. This talk examines how machine learning techniques can be used to cluster and classify test outputs to separate failing and passing cases. The feasibility of the approach is demonstrated and shown to have the potential to reduce by an order of magnitude the numbers of outputs that need to be examined following a test run. This is joint work carried out with Rafig Almaghairbe. --------------------------------------------------- Hertfordshire Computer Science Research Colloquium http://homepages.herts.ac.uk/~nehaniv/colloq/
