TestBase is a diagnostic controller adequate for system-level testing, providing visual development, database storage and run-time execution of "fault tree" test strategies. TestBase may act as the backbone of a modular, open and distributed ATS framework, integrating third-party products such as: diagnostic reasoners, test procedure execution environments, document/report display applications, maintenance information storage applications, etc.

The main features of TestBase are:

• uses "fault tree" test strategies modeled by Control Flow Diagrams, which include calls to external test procedures
• supports the execution of test procedures developed in multiple languages and environments; support for additional environments may be added by system integrators
• supports the display of documents and reports with multiple formats
• contains an Integrated Development Environment (IDE) allowing the visual design and debugging of test strategies
• provides database storage for test, diagnostic and maintenance data
• Compared with similar products, TestBase offers the following benefits:
• combines the simplicity of visual design for test strategies with the versatility of textual languages for test procedure development
• supports the system-level diagnosis of complex UUTs by providing high-capacity database storage for test strategies and parametric data and by allowing the integration of intelligent diagnostic reasoners
• supports the increase of development productivity by separating the diagnosis from the actual testing operations
• favors code reuse
