The document compares and contrasts the V-model and agile testing approaches. The V-model involves sequential development and testing phases, while agile testing is iterative with the entire team sharing responsibility for quality. Agile testing allows for quicker feedback, accommodation of changes, and more practical implementation of unit and integration testing within iterations rather than as separate phases. The document lists advantages of the agile approach and disadvantages of the sequential V-model.

6. Why we prefer Agile Testing Advantages of Agile: The entire team takes the responsibility for quality Just the right amount of documentation Quicker feedback Accommodate changes

7. Why Agile testing? Contd… Disadvantages of V-model: V model does nothing to accommodate change Implementation of unit tests or integration tests as separate phases is not a practical approach
