How do you manage test data across multiple environments in TOSCA?

Managing test data across multiple environments in TOSCA starts with using centralized Test Data Management (TDM) modules to separate data from test cases. I typically create reusable data templates and environment-specific data sets, then map them dynamically using buffers and parameterization. This allows the same automation to run smoothly in QA, UAT, and staging without rewriting scripts. Version control for data files is also critical to maintain consistency and traceability. From my experience and through TOSCA Training Online, learning to automate data refresh, masking, and validation helps teams reduce defects, improve reliability, and accelerate continuous testing across complex enterprise systems.
