Agile testing is used to enhance software quality due to its iterative and collaborative approach that aligns testing activities with agile development methodologies. Here are the reasons why agile testing is beneficial for enhancing software quality:

1. Early and Continuous Feedback: Agile testing emphasizes early and continuous feedback throughout the development process.
2. Adaptability to Change: Agile testing embraces the inherent flexibility of agile methodologies. Testers can quickly respond to changing requirements, new features, or evolving business needs.
3. Continuous Integration and Continuous Delivery (CI/CD): Agile testing integrates seamlessly with CI/CD practices. Automated testing is frequently executed as part of the continuous integration process, enabling rapid feedback on the quality of code changes. This helps in identifying integration issues, regression bugs, and performance bottlenecks early on, reducing the time and effort required for debugging and fixing issues.
4. Test-Driven Development (TDD): Agile testing promotes test-driven development, where tests are written before the code is implemented. Testers collaborate with developers to define acceptance criteria and create automated tests to validate the expected behavior.
5. Continuous Improvement: Agile testing embraces a culture of continuous improvement.

By combining these factors, agile testing provides a dynamic and collaborative environment that focuses on delivering high-quality software. The early and continuous feedback, adaptability to change, collaborative environment, incremental testing, integration with CI/CD practices, test-driven development, and continuous improvement contribute to enhanced software quality and customer satisfaction in agile development projects.
