Acceptance test criteria are the conditions that a user story must satisfy to be accepted by the customer or the stakeholder. They are usually derived from the user story and its acceptance scenarios, and they should cover the functional and non-functional requirements of the user story. Acceptance test criteria should be clear, concise, testable, and agreed upon by the team and the customer or the stakeholder.

In this case, the user story describes the business rule for approving a loan request based on the customer’s income, repayment history, and loan amount. The user story also specifies the roles of the customer assistant and the bank manager in the process. Therefore, the acceptance test criteria should verify that the user story is implemented correctly and that the system behaves as expected for different scenarios and inputs.

The following test cases can be treated as acceptance test criteria for the above user story:

• As a customer assistant I can log in to the system and check the history of the customer account for the last year. This test case verifies that the customer assistant can access the system and view the customer’s income information, which is one of the factors for approving the loan request.
• As a customer assistant I can log in to the system and check the history of the customer debts and repayments. This test case verifies that the customer assistant can access the system and view the customer’s repayment history, which is another factor for approving the loan request.
• As a bank manager I can log in to the system and receive the information of all requests waiting for approval. This test case verifies that the bank manager can access the system and see the list of loan requests that have been prepared by the customer assistant, and that the system provides the necessary information for each request.
• As a bank manager I can log in to the system and decide whether to approve a loan for a customer. This test case verifies that the bank manager can access the system and perform the approval action for a loan request, and that the system applies the business rule correctly and updates the status of the request accordingly.

The following test cases cannot be treated as acceptance test criteria for the above user story:

• As a customer assistant I can log in to the system and change my password. This test case is not related to the user story, as it does not verify any of the functional or non-functional requirements of the user story. It is a generic test case that applies to any user of the system, not specific to the customer assistant role or the loan approval process.
• As a bank manager I can log in to the system within 10 seconds. This test case is not related to the user story, as it does not verify any of the functional or non-functional requirements of the user story. It is a performance test case that applies to any user of the system, not specific to the bank manager role or the loan approval process.

The whole-team approach is a principle of agile testing that involves everyone with different knowledge and skills to ensure project success. The whole-team approach means that the business representatives, testers, and developers work together in every step of the development process, from planning to delivery. The whole-team approach aims to enhance communication and collaboration within the team, leverage the various skill sets of the team members, and make quality everyone’s responsibility12. Therefore, the statement C is the most direct advantage of the whole-team approach, as it captures the essence of the principle and its benefits. The other statements are not directly related to the whole-team approach, or are incorrect. Statement A is about continuous integration, which is a practice of agile development that involves having at least once a day an automated build and test process that detects integration errors early and quickly. Continuous integration is not a direct consequence of the whole-team approach, although it may be facilitated by it13. Statement B is about avoiding requirements misunderstandings, which may be a benefit of the whole-team approach, but not the most direct one. The whole-team approach does not only focus on requirements, but also on design, implementation, testing, and delivery. Moreover, avoiding requirements misunderstandings may also depend on other factors, such as the quality of the user stories, the use of acceptance criteria, and the feedback from the customers and users14. Statement D is incorrect, as it contradicts the whole-team approach. The whole-team approach does not reduce the involvement of business representatives, but rather increases it. Business representatives are an integral part of the whole-team approach, as they provide the vision, the value, and the validation of the product. They collaborate with the testers and developers to define the features, prioritize the backlog, and verify the outcomes12. References: ISTQB Foundation Level Agile Tester Syllabus1, Section 1.2.1, page 9; What is Whole Team Approach in Agile Testing?2, Section What is Whole Team Approach?; Continuous Integration3, Section What is Continuous Integration?; Effective User Stories - 3C’s and INVEST Guide4, Section The 3 C’s (Card, Conversation, Confirmation) of User Stories.

The best black box test design technique for verifying the accuracy of this user story is equivalence partitioning. Equivalence partitioning is a technique that divides the input domain of a system into classes or groups that are expected to behave similarly. By testing one value from each class, the tester can reduce the number of test cases while still achieving good coverage. In this case, the input domainof the system is the amount of income, which can be divided into classes based on the tax percentage applied to different income ranges. For example, if the tax percentage is 10% for income below 10,000, 20% for income between 10,000 and 20,000, and 30% for income above 20,000, then the equivalence classes are: low income (<10,000), medium income (10,000-20,000), and high income (>20,000). By testing one value from each class, such as 5,000, 15,000, and 25,000, the tester can verify that the system calculates the correct tax percentage for each income range. This technique is more efficient and effective than testing all possible values of income, or testing only one value of income, or testing the states of income entry, or testing the statements in income calculation. References: ISTQB Foundation Level Agile Tester Syllabus1, Section 2.3.1, page 19; ISTQB Foundation Level Agile Tester Extension Sample Exam Questions2, Question 5, page 6.
