How are pyATS Test Suites formatted?

pyATS Test Suites are formatted as YAML-based text files. YAML (YAML Ain't Markup Language) is designed to be human-readable and is often used for configuration files and data serialization. In the context of pyATS, using YAML allows for defining test cases and their configurations in a clear and structured way, making it easier for developers and testers to understand and manage their test suites.

YAML's simplicity and readability contribute to its popularity in automation and testing environments, especially when large and complex configurations need to be easily edited by users. This is particularly useful in networking, where test cases may involve various parameters and configurations that need to be documented or communicated effectively. The choice of YAML in pyATS streamlines the process of writing, modifying, and sharing test suites, enabling automation in network testing more efficiently.
