A test-suite generator for database systems

In this paper, we describe the SPAR Test Suite Generator (STSG), a new test-suite generator for SQL style database systems. This tool produced an entire test suite (data, queries, and ground-truth answers) as a unit and in response to a user's specification. Thus, database evaluators could use this tool to craft test suites for particular aspects of a specific database system. The inclusion of ground-truth answers in the produced test suite, furthermore, allowed this tool to support both benchmarking (at various scales) and correctness-checking in a repeatable way. Lastly, the test-suite generator of this document was extensively profiled and optimized, and was designed for test-time agility.
