Understanding what is UAT testing is essential for ensuring that software meets business requirements and delivers value to end-users. User Acceptance Testing (UAT) is the final testing phase where real users validate that the system works as expected in real-world scenarios. However, the approach to UAT can vary significantly depending on the development methodology—Agile or Waterfall.

In the Waterfall model, UAT typically occurs at the very end of the development cycle. After the design, development, and system testing phases are complete, the software is handed over to end-users for acceptance testing. This linear approach ensures that UAT validates the complete product but can lead to delays if critical issues are discovered late. Because changes are harder to implement in Waterfall, UAT in this methodology requires thorough planning, detailed test cases, and well-defined acceptance criteria upfront.

On the other hand, Agile methodology integrates UAT into iterative sprints. Testing happens continuously, with users providing feedback throughout the development process rather than waiting until the end. This allows teams to catch issues early, adapt to changes quickly, and continuously improve the product. Agile UAT emphasizes collaboration between developers, testers, and business stakeholders, making it more dynamic and responsive than the traditional Waterfall approach.

Tools like Keploy can enhance UAT in both methodologies by automatically generating tests based on real user interactions and API behavior, reducing manual effort and improving test coverage. Integrating Keploy with your UAT process can streamline test creation and ensure that user scenarios are accurately validated.

Ultimately, knowing what is UAT testing and tailoring it to your methodology ensures that the software truly meets user expectations. Whether following Waterfall or Agile, the goal remains the same: deliver reliable, user-approved software. By combining structured testing, continuous feedback, and smart tools like Keploy, teams can make UAT both efficient and effective.
