4. Test-driven development: Test-driven development is an approach to software development that involves writing tests before writing code. This approach helps to ensure that the code meets the requirements and that it is tested thoroughly.

Test-driven development involves writing a test case for a specific feature or function before writing the code for that feature or function. The code is then developed to pass the test case. By using this approach, teams can ensure that the software meets the requirements and that it is tested thoroughly throughout the development process.

5. Continuous integration and delivery: Agile testing emphasizes the need for continuous integration and delivery, which involves continuously integrating code changes into the main branch and delivering new software updates to customers. Continuous integration and delivery help to ensure that code changes are tested thoroughly and that new features and functions are delivered to customers more quickly.

Continuous integration involves integrating code changes into the main branch on a regular basis. This helps to identify integration issues early in the development process when they are less expensive to fix. Continuous delivery involves delivering new software updates to customers on a regular basis. This helps to ensure that customers have access to new features and functions as soon as they are available.

The key principles of agile testing are critical to its success. By emphasizing continuous testing and feedback, collaboration, automated testing, test-driven development, and continuous integration and delivery, teams can deliver high-quality software that meets the needs of the customer. Implementing agile testing requires a cultural shift within an organization, but the benefits of this approach are clear, including faster time to market, higher quality software, increased collaboration, and improved customer satisfaction.
