An Ada based real-time closed-loop integration and regression test tool

The ability to perform thorough regression testing is especially critical for software maintenance in order to ensure that changes made to correct problems or add capabilities do not affect the integrity of the complete software system. The Universal Ada Test Language (UATL), a DoD sponsored project established to meet these requirements, is described. The UATL design, test manager, test program generation tool and capabilities demonstration are discussed. The UATL provides a consistent framework for testing complex systems at all stages of the software/system development, production and maintenance cycle
