In Agile, testing is no longer a separate phase that happens after development — it is embedded in every sprint, with QA actively involved from the start. The QA role evolves into a collaborative, continuous, and customer-focused contributor to the team.

Detailed Explanation

In Agile methodology, testing does not occur as a final step after all development has been completed. Instead, it is integrated throughout the entire development process, specifically in each sprint. This means that Quality Assurance (QA) professionals participate early in the development cycle, working alongside developers. This continuous collaboration allows for a focus on quality from the beginning.

Examples & Analogies

Think of Agile testing like preparing a meal. Instead of cooking everything first and then checking if it tastes good at the end, you taste and adjust the flavors while you cook. This way, you can ensure each ingredient is perfect, leading to a delicious final dish.
