This paper compares traditional script-based testing with model-based testing (MBT). Page 1 shows a contrasting visual of code scripts vs. visual models. Script-based testing is manual, brittle, and hard to maintain as applications evolve. MBT generates tests automatically from process models, improving coverage and reducing maintenance. The document explains how MBT accelerates regression testing, supports parallel execution, and detects defects earlier. It evaluates learning curves, scalability, tool integration, and ROI. Best-fit scenarios for each approach are provided, emphasizing MBT benefits for dynamic, complex, multi-device applications.
