What are the different UAT techniques used in the SDLC?

There are several User Acceptance Testing (UAT) techniques used in the Software Development Life Cycle (SDLC). Some of the commonly used UAT techniques include:

1. Alpha Testing: This technique involves testing the software in a controlled environment by the development team before releasing it to external users. It helps identify any major issues or bugs before moving to the next phase.

2. Beta Testing: In this technique, the software is released to a limited number of external users who provide feedback on its usability, functionality, and performance. This helps in identifying any potential issues or improvements before the final release.

3. Exploratory Testing: This technique involves testers exploring the software without any predefined test cases. They interact with the software as end-users would and provide feedback based on their experience. It helps uncover any unexpected issues or usability problems.

4. Usability Testing: This technique focuses on evaluating the software's user-friendliness and ease of use. Testers perform tasks and provide feedback on the software's intuitiveness, navigation, and overall user experience.

5. Regression Testing: This technique involves retesting previously tested functionalities to ensure that any changes or additions to the software have not introduced new defects or impacted existing functionalities.

6. Acceptance Testing: This technique is performed by end-users or stakeholders to determine whether the software meets their requirements and expectations. It involves executing predefined test cases and validating the software against the agreed-upon acceptance criteria.

7. Automated Testing: This technique involves using automated tools to execute test cases and validate the software's functionality, performance, and reliability. It helps in reducing manual effort and increasing test coverage.

These UAT techniques play a crucial role in ensuring that the software meets the desired quality standards and user expectations before its final release.
