| Aspect | Compatibility Testing | Functional Testing |
|---|
| Purpose | To ensure software works across different devices, browsers, and environments | To verify that software functions according to specified requirements |
| Focus | Environment and platform compatibility | Application features and functionalities |
| Tools | Browser compatibility tools, device simulators | Test automation tools, test scripts |
| Work Environment | Testing across multiple devices and OS | Testing within a controlled environment, often in a lab or virtual setup |
Compatibility Testing and Functional Testing are both essential in software quality assurance but focus on different aspects. Compatibility Testing ensures the software performs well across various environments, while Functional Testing verifies that all features work correctly. Both roles often require similar skills and tools, making them closely related in the testing process.
