ISTQB Exam ISTQB-Agile-Public Topic 1 Question 5 Discussion

In agile projects, the high risk of regression is primarily due to the code churn that occurs as business needs change over the course of several sprints. This is inherent in the agile process, where requirements and solutions evolve through collaborative effort. The iterative nature of agile projects means that as new features are added or existing features are modified to meet evolving business needs, previously tested and stable parts of the software might be affected, leading to potential regression issues. This phenomenon is well-recognized in agile methodologies and necessitates rigorous regression testing practices to ensure that new changes do not adversely affect existing functionalities.
