What are the different software quality assurance techniques used in the SDLC?

There are several software quality assurance techniques used in the Software Development Life Cycle (SDLC). Some of the commonly used techniques include:

1. Code reviews: This involves reviewing the code written by developers to identify any potential bugs, errors, or vulnerabilities.

2. Unit testing: It is a technique where individual components or units of the software are tested to ensure they function correctly.

3. Integration testing: This technique involves testing the interaction between different components or modules of the software to ensure they work together seamlessly.

4. System testing: It is a technique where the entire system is tested to ensure it meets the specified requirements and functions as expected.

5. Acceptance testing: This technique involves testing the software with end-users or stakeholders to ensure it meets their expectations and requirements.

6. Regression testing: It is a technique where previously tested functionalities are retested to ensure that any changes or additions to the software have not introduced new bugs or issues.

7. Performance testing: This technique involves testing the software's performance under different conditions to ensure it can handle the expected workload and perform efficiently.

8. Security testing: It is a technique where the software is tested for vulnerabilities and weaknesses to ensure it is secure against potential threats.

9. Usability testing: This technique involves testing the software's user interface and user experience to ensure it is intuitive, easy to use, and meets the needs of the end-users.

10. Continuous integration and continuous delivery (CI/CD): This technique involves automating the testing and deployment processes to ensure frequent and reliable software releases.

These techniques help ensure the quality, reliability, and functionality of the software throughout the SDLC.
