A data-driven approach to test automation design is best characterized by what?

A data-driven approach to test automation design is best characterized by separating out test data inputs with a generic script that can read the data. This methodology allows testers to maintain a single test script that can execute multiple test cases by varying the input data, which enhances efficiency and manageability. It decouples the test logic from the test data, enabling rapid changes to the data without needing to alter the script itself. This separation supports the reuse of scripts for different scenarios, making it easier to test various data sets effectively.

In a data-driven framework, the test execution is flexible, allowing data to be stored in external files, databases, or other storage systems. This contrasts with other approaches that may not prioritize this level of separation, which can lead to a more cumbersome and less maintainable testing strategy.
