In Agile development, testing is typically:

In Agile development, testing is performed in every iteration as part of the overall development process. This approach is integral to Agile methodologies, emphasizing continuous feedback and improvement. Each iteration, often referred to as a sprint, includes not only development activities but also testing activities. This iterative cycle allows for early identification of defects, ensures that features meet acceptance criteria, and facilitates adaptations based on stakeholder feedback.

By integrating testing into each iteration, Agile teams can maintain a high level of software quality and respond quickly to changes or new requirements. This contrasts with traditional development methods, where testing might occur only after the completion of a project, as a separate phase, or might be limited to specific types of testing like acceptance testing. The Agile philosophy supports collaboration among developers, testers, and stakeholders throughout the development lifecycle, thereby enhancing overall project success.
