Consider an online application that allows registered users to pay the annual car tax based on the vehicle's engine power in kW. Given the following user story:
''As a customer I need the online application to calculate the annual car tax amount that I need to pay for my car":
- If the power of the vehicle is less than 20 kW, then the annual car tax is free
- If the power of the vehicle is more or equal than 20 kW but less or equal than 150 kW, then the annual car tax is 250 Euros
- If the power of the vehicle is more than 150 kW, then the annual car tax is 750 Euros"

Which of the following sentences about the integration of development and testing activities in Agile projects is INCORRECT?
SELECT ONE OPTION
In Agile projects, the integration of development and testing activities involves close collaboration between developers and testers, but it does not typically involve testers replacing developers in writing unit test automation scripts. Agile methodologies, such as Scrum and XP (Extreme Programming), encourage developers to write their own unit tests as part of the Test-Driven Development (TDD) process. Testers often focus on higher-level testing activities, such as acceptance testing and exploratory testing, and may work alongside developers to enhance test coverage and effectiveness. The incorrect statement about testers replacing developers in writing unit test automation scripts contradicts the Agile principle of developers being responsible for the quality of their code, which includes writing and maintaining unit tests.
Why is regression of software a high risk in agile projects?
SELECT ONE OPTION
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.
Which of the following sentences related to Risk-based testing is CORRECT?
SELECT ONE OPTION
Risk-based testing is a strategic approach to testing that prioritizes testing activities based on the level of risk associated with various features or components of the software. In Agile development, this approach aligns well with the iterative and incremental nature of Agile methodologies. During both release and iteration planning, Agile teams assess and prioritize work based on risk, value, and other factors. This double layer of risk analysis allows teams to focus their testing efforts more effectively on areas that pose the greatest risk to the project's success, thereby enhancing the quality and reliability of the deliverables. This approach is consistent with Agile principles, which emphasize adaptability and the delivery of value to the customer.
