Data-Driven Testing: What it is, How it Works, and Tools to Use
Sep 29, 2025 · Data-driven testing is a powerful and practical testing methodology for improving software quality . By separating test logic from test data, teams gain greater reusability, scalability and maintainability.
The data- driven testing methodology consists of running the same test repeatedly using different data values with each new iteration. This has the benefit of improved test coverage with less development effort.
Test Cases can be written in a data- driven style where test cases use only one higher-level keyword, that hides the actual test workflow. These tests are very useful when there is a need to test the same scenario with different input and/or output data.
