An agile team is in their 2nd iteration planning session.

In Agile, continuous integration and regression testing should be part of every iteration to ensure that the product is always in a potentially shippable state. These practices help catch issues early in the development process, preventing defects from accumulating and becoming harder to fix later. By integrating and testing frequently, the team ensures that new code works with existing code and that the product maintains its quality throughout the development lifecycle. This approach aligns with Agile principles of delivering working software regularly and maintaining high-quality standards throughout each iteration.
