QuickCheck offers automated property-based testing that generates diverse inputs to quickly detect bugs, scales well for complex codebases, and uncovers edge cases efficiently without manual scripting. In contrast, traditional unit tests rely on manually crafted scenarios for known outcomes, often missing unexpected bugs and requiring more time for comprehensive coverage.

Advantages vs. Traditional Testing
