TDL (Test Description Language), is a high-level, abstract language designed to describe test cases in a technology-agnostic and human-readable way. Its strength are:
- Abstract and reusable test logic
- Technology-independent
- Bridges requirements and executable tests
- Ideal for standardized testing in domains like IoT, Telecom, and Cybersecurity
