Generating targeted queries for database testing
Chaitanya Mishra, Nick Koudas, Calisto Zuzarte · 2008
Tools for generating test queries for databases do not explicitly take into account the actual data in the database. As a consequence, such tools cannot guarantee suitable coverage of test cases commonly required for database testing. In this paper, we investigate the problem of generating queries that satisfy cardinality constraints on intermediate subexpressions when executed on a given test database. Such queries are required to test the performance of a database system under different operating conditions.
