CTFL-AT Certified Tester Foundation Level Agile Tester Questions and Answers

 Business-oriented work products are those that describe what is needed (e.g., requirements specifications) and how to use it (e.g., user documentation). A user manual is an example of a business-oriented work product, as it provides instructions and guidance on how to use the product from the user’s perspective. A user manual may also contain information about the product’s features, benefits, and limitations. A user manual is typically written by technical writers, who may collaborate with developers, testers, and business analysts to ensure the accuracy and clarity of the content. A user manual may be delivered in various formats, such as printed, online, or interactive. References: ISTQB® Foundation Level Agile Tester Syllabus1, Section 1.2.1, page 10; ASTQB Agile Tester Certification Resources2, Section 1.2.1, page 10.

The Agile Manifesto is a declaration of four values and twelve principles that guide the Agile software development approach12. The four values of the Agile Manifesto are12:

• Individuals and interactions over processes and tools
• Working software over comprehensive documentation
• Customer collaboration over contract negotiation
• Responding to change over following a plan

These values emphasize the importance of human collaboration, working product, customer feedback, and adaptability over rigid processes, extensive documentation, fixedcontracts, and predefined plans. The values do not imply that the items on the right are not important, but rather that the items on the left are more important and should be prioritized.

Therefore, the statement that is NOT a value from the Agile Manifesto is B, as it contradicts the first value of the Agile Manifesto. The correct statement should be “Individuals and interactions over processes and tools”. References: ISTQB Foundation Level Agile Tester Extension Syllabus1, page 10; ISTQB Agile Tester Sample Exam2, question 1.

Risk-based testing is a technique that prioritizes testing activities based on the level of risk associated with each feature or requirement. The level of risk is usually calculated by multiplying the probability and impact of each risk. The higher the risk level, the more testing effort should be allocated to mitigate the risk. In this case, the risk level for each option is as follows: A. Risk level = Low x Low = Low B. Risk level = Low x High = Medium C. Risk level = High x High = High D. Risk level = High x Low = Medium Therefore, the highest risk level is C, followed by B and D, and then A. The User Story for the Operator-Instructions module should be tested according to this risk order, starting with C, then B, then D, and finally A. Hence, the answer is B, as it is the second highest risk level and should be tested after C. References: ISTQB Foundation Level Agile Tester Extension Syllabus1, page 16; ISTQB Agile Tester Sample Exam2, question 18.

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.

Test automation is essential for agile projects, as it enables fast and frequent feedback on the quality of the product. Without test automation, it would be very difficult to ensure high quality in an agile project, as manual testing would be too slow and costly to keep up with the pace of development12. Automated acceptance tests are one of the key types of test automation on agile projects, as they verify that the user stories are implemented correctly and that the product meets the customer’s expectations. Automated acceptance tests are run regularly as part of the continuous integration full system build, and the results provide feedback on the overall product quality12. Therefore, statements 2 and 5 are correct with regards to test automation on agile projects. References: 1: ISTQB® Foundation Level Agile Tester Syllabus, Section 3.3.1, Test Automation1; 2: ASTQB Agile Tester Certification Resources, Section 3.3.1, Test Automation2

 Planning poker is a consensus-based technique for agile estimation, using a deck of cards with predefined numerical values, usually based on the Fibonacci sequence or a modified version12. Therefore, statement 1 is correct. A high test estimate usually means that the user story or task is too complex, ambiguous, or risky, and should be broken down into multiple smaller stories that are easier to understand and estimate13. Therefore, statement 3 is correct. The risk level of each backlog item should be decided before the poker session, as it can affect the estimation process and the prioritization of the work14. Therefore, statement 5 is correct. Statement 2 is incorrect, as a low test estimate usually means that the user story or task is simple, clear, and well-defined, and does not need to be broken down further13. Statement 4 is incorrect, as planning poker can involve multiple rounds of estimation, reveal, and discussion, until the team reaches a consensus or agrees to defer the item12. References: 1: ISTQB® Foundation Level Agile Tester Syllabus, Section 3.3.1, Test Automation1; 2: ASTQB Agile Tester Certification Resources, Section 3.3.1, Test Automation2; 3: Planning Poker: An Agile Estimating and Planning Technique3; 4: Planning poker: The all-in strategy for Agile estimation - Asana4

 Equivalence partitioning is a black-box test design technique that divides the input domain of a system into classes of data from which test cases can be derived. The idea is that if a system works correctly for a representative value from an equivalence class, it will work correctly for all values from that class, and vice versa. Equivalence partitioning reduces the number of test cases by eliminating redundant ones. For the given user story, equivalence partitioning is the most suitable technique because it can test the different outcomes of the annual car tax calculation based on the power of the vehicle, which is the main input for the system. By testing one value from each partition, the tester can verify the functionality of the system and detect any errors in the calculation logic. The other techniques are not as suitable because they do not focus on the inputdomain of the system, but rather on the conditions, transitions, or scenarios that are not directly related to the user story. References:

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.

A tester on an Agile project typically performs the following tasks12:

• Implementing test strategy: A tester helps to define and implement the test strategy for the Agile project, which includes the test approach, test levels, test types, test techniques, test tools, test environment, test data, test metrics, and test documentation.
• Measuring and reporting test coverage: A tester measures and reports the test coverage of the product features and quality attributes, such as functionality, usability, performance, security, etc. Test coverage can be expressed in terms of test cases, test scenarios, test sessions, test conditions, test data, code, etc.
• Coaching development team in relevant aspects of testing: A tester coaches the development team in relevant aspects of testing, such as test design, test execution, test automation, test-driven development, behavior-driven development, exploratory testing, etc. A tester also helps the development team to improve their testing skills and practices.

The following tasks are not typically performed by a tester on an Agile project:

• Documenting business requirements: Business requirements are usually documented by the product owner or the business analyst, not by the tester. The tester may review and provide feedback on the business requirements, but the tester is not responsible for documenting them.
• Executing test-driven development tests: Test-driven development tests are usually executed by the developers, not by the tester. The tester may assist the developers in creating and reviewing the test-driven development tests, but the tester is not responsible for executing them.

Therefore, the correct answer is C, as it contains the tasks that are typically performed by a tester on an Agile project. References: ISTQB Foundation Level Agile Tester Extension Syllabus1, pages 14-15, 18-19, 22-23; ISTQB Agile Tester Sample Exam2, question 17.
