Key Strategies for Architecting Test Systems with TestStand

Successfully architecting test systems with TestStand requires a strong grasp of its modular framework, customizability, and data handling capabilities. This section outlines the strategies TestStand Architects should focus on when designing and implementing complex test systems.

  • Develop a Modular Structure: Break down test requirements into smaller, reusable components. Use sequences and sub-sequences to build modular tests, making them easier to maintain and update.
  • Leverage Custom Step Types and Templates: Tailor step types and create templates that meet specific test requirements. This approach ensures consistency across test sequences and reduces development time.
  • Implement Scalable Error-Handling Mechanisms: Effective error handling is critical in TestStand architecture. Use central error-handling routines and define robust strategies for handling exceptions to ensure reliable test operation.
  • Optimize Data Logging and Management: Design an efficient data flow by integrating with database systems or other data management tools. Configure logging to capture only essential data, minimizing storage needs and speeding up report generation.

These strategies not only improve the quality and scalability of test systems but also reduce the time needed to develop and troubleshoot complex test environments.
