What does an iterative testing phase focus on during software development?

In software development, the iterative testing phase primarily focuses on bug fixing. This phase is characterized by repeated cycles of testing and development, allowing developers to identify and resolve issues that arise during the creation of the software. By continuously testing the software at various stages, developers can catch bugs early and ensure that the software functions correctly. This process also enables them to refine the code and improve overall reliability.

While other aspects are essential to the overall software development process—like testing for features, enhancing performance, and evaluating user experience—the key emphasis during the iterative testing phase is on identifying, diagnosing, and resolving any defects or glitches in the software. This proactive approach helps in maintaining the quality of the final product.
