The company is changing its business model and must run a complex project using multiple agile teams. Which three testing approaches should the project manager have the testing team adopt? (Choose three.)

Story testing ensures that each user story is implemented correctly and meets its acceptance criteria, which is fundamental in agile development. Tests based on behavior-driven development (BDD) and test-driven development (TDD) promote collaboration and ensure that code is developed with testability and requirements in mind, leading to higher quality and fewer defects early in the lifecycle. Security and performance testing are crucial non-functional tests that assess the system's resilience against threats and its ability to handle expected loads, which are vital for complex projects and changing business models. Independent personal testing is not a recognized agile testing approach. An experimental approach to cover all possible choices is too broad and impractical for a structured testing strategy.
