Description: Agile Testing Quadrants are a model that categorizes different types of testing within the agile development framework, facilitating the understanding and implementation of effective testing strategies. This model is based on the idea that testing should be integrated into the development process from the outset, rather than being a separate phase at the end of the software lifecycle. The quadrants are divided into four categories: the first quadrant focuses on unit and integration testing, which are verification techniques that ensure each component of the software functions correctly. The second quadrant includes functional and user interface testing, which validate that the system meets user requirements. The third quadrant encompasses non-functional testing, such as performance and security, which evaluate critical aspects of the software that are not directly related to functions. Finally, the fourth quadrant refers to exploratory and acceptance testing, which allow end users to interact with the software and provide feedback. This approach not only improves the quality of the final product but also fosters a culture of collaboration and communication between development and testing teams, ensuring that everyone is aligned with the project’s goals.
