When should test planning be performed according to best practices?

The best practice for test planning emphasizes that it should be a continuous process throughout all lifecycle phases and activities. This approach acknowledges that as the project progresses, new information, changes in requirements, or feedback can emerge that may impact testing strategies, resources, and timelines.

By integrating test planning into each phase of the software development lifecycle, testers can adapt their plans to suit evolving circumstances, ensuring that they remain relevant and focused. Continuous test planning enables teams to maintain alignment with project goals, manage risks effectively, and ensure that testing efforts are optimized throughout the project rather than being constrained to a single phase.

This continuous approach promotes proactive adjustments and informed decision-making, ultimately leading to enhanced quality and efficiency in the testing process. It embodies the idea that testing is not just an isolated phase but an integral part of the overall development process that requires ongoing attention and adaptation.
