The document discusses testing in agile projects through a case study. It presents four case examples of companies using agile methodologies and discusses both benefits and challenges of testing in agile projects. Specifically, it notes that agile practices like incremental development help ensure quality at the end of each iteration. However, agile also demands discipline from teams and individuals and can be difficult for testers accustomed to more traditional roles. The document concludes that in agile, testing is a function all team members contribute to rather than a separate role.
