Executive Summary

Adequacy criteria provide an objective measurement of test quality. Although these criteria are a major research issue in software testing, little work has been specifically targeted towards the testing of database-driven applications. In this paper, two structural coverage criteria are provided for evaluating the adequacy of a test suite for SQL queries that retrieve information from the database. The first deals with the way in which the queries select and join information from different tables and the second with the way in which selected data is further processed.
