Mutation Testing for Java Database Applications

Database application programs are ubiquitous, so good techniques for testing them are needed. Recently, several research groups have proposed new approaches to generating tests for database applications and for assessing test data adequacy. This paper describes a mutation testing tool, JDAMA (Java database application mutation analyzer), for Java programs that interact with a database via the JDBC interface. Our approach extends the mutation testing approach for SQL by Tuya et al, by integrating it with analysis and instrumentation of the application bytecode. JDAMA´s use is illustrated through a small study which uses mutation scores to compare two test generation techniques for database applications.
