Postman's test scripts are advantageous for continuous integration when verifying the functionality of a web-based API. Postman provides a user-friendly interface for creating and executing API requests, making it an excellent tool for testing the functionality, performance, and reliability of APIs in a CI/CD pipeline. The ability to automate API testing in Postman allows for the early detection of issues and ensures that the API endpoints function as expected throughout the software development lifecycle.

In a cross-functional team, roles and responsibilities should be clearly defined, but collaboration among team members is crucial for testing efficiency. Assigning testing tasks only to dedicated testers may create silos and hinder collaboration. By clearly defining roles and encouraging collaboration, team members can leverage their diverse skills and work together to ensure comprehensive testing, leading to improved efficiency and effectiveness in the testing process.
