 Equivalence partitioning is a technique that divides the input domain of a system into partitions or classes that are expected to behave similarly or produce similar outputs2. A test case can cover one value from each partition, as it is assumed that all values in the same partition are equivalent for testing purposes2. In this question, the groups of numbers fall into different equivalence classes based on the amount of customs duty to be paid, as shown below:

Group

Equivalence Classes

$20,000 $20,001 $30,001

No duty (up to $2,000), 10% duty ($2,001-$10,000), 12% duty ($10,001-$30,000), 17% duty (above $30,000)

$2,000 $2,001 $10,000

No duty (up to $2,000), 10% duty ($2,001-$10,000), 12% duty ($10,001-$30,000)

$2,000 $8,000 $20,000

No duty (up to $2,000), 10% duty ($2,001-$10,000), 12% duty ($10,001-$30,000)

$1,500 $2,000 $10,000

No duty (up to $2,000), 10% duty ($2,001-$10,000)

 Having the company’s independent test team design and execute the tests would achieve the highest level of testing independence for a project’s test level, because it would reduce the bias and influence of the developers or other stakeholders who are involved in the software development1 . An independent test team can provide a different perspective and focus on testing activities without being affected by development pressures or deadlines1 . The other options would not achieve the highest level of testing independence for a project’s test level. Option A is not a good option, because training developers to design good tests for the test team to execute would still introduce some bias and influence from the developers’ point of view1 . Option C is not a good option, because minimizing contact between testers and developers during test design to avoid bias would reduce the communication and collaboration that are essential for effective testing and defect resolution1 . Option D is not a good option, because outsourcing test design and execution to a different company would introduce some risks and challenges such as contractual issues, cultural differences, or loss of control over quality

 The correct roles and responsibilities in a formal review are as follows1:

• Review Leader - Plans and leads the review process
• Scribe - Documents all issues raised during the review meeting
• Author - Creates the work product under review
• Facilitator - Supports the review leader in conducting the review process
• Reviewers - Identify potential defects in the work product under review

Therefore, option B is the correct answer, as it correctly matches the role of scribe with the responsibility of collating potential defects found during the individual review activity. Options A, C, and D are incorrect, as they do not match the roles and responsibilities correctly. References: 1, Section 3.2.3

The correct matching of the descriptions with the different categories of test techniques is as follows:

• Black-box test techniques: Test cases are based on the test basis which may include the requirements, use cases and user stories (1), Test cases can show deviations from the requirements (3), These test techniques are applicable to both functional and non-functional testing (4)
• White-box test techniques: Test cases are based on the test basis which may include the software architecture or code (2)
• Experience-based test techniques: Tests are based on knowledge of developers, users and other stakeholders (5)

Therefore, option D is the correct answer. Options A, B, and C are incorrect, as they do not match the descriptions with the different categories of test techniques correctly.
