The software development practice involving continuous testing and integration is called DevOps. This methodology emphasizes collaboration between development and operations teams, fostering a culture of communication and shared responsibility throughout the software lifecycle. Continuous testing allows for immediate feedback on code quality and functionality, helping identify issues early in the development process. Such integration reduces the risk of delays and enhances the overall efficiency of software delivery. By implementing DevOps practices, organizations can ensure faster releases, higher quality code, and more reliable applications.
