Bacterio ORACLE: An Oracle suggester tool

摘要

One of the main challenges during testing is to design good oracles. An oracle is one or more statements in a test that evaluate the behavior of the system. This paper presents a tool, BacterioORACLE, based on mutation testing that helps testers to write good oracles. The tool generates oracle suggestions automatically analyzing information obtained from killed mutants. These suggestions are useful to discover errors and can be translated into executable oracles easily. Thus, this tool can be very useful during the testing process in order to create good oracles.
