The test conditions are the inputs and outputs that are used to define the scope and objectives of testing. They should be understandable by business stakeholders because they affect their expectations and satisfaction with the software product. Business stakeholders can provide valuable feedback to the test analyst on the test conditions, such as clarifying any ambiguities, suggesting any changes, or identifying any gaps or risks. References =

Equivalence partitioning is a technique that divides the input domain into classes of data that are expected to behave similarly. The test sets should cover one value from each equivalence class, as well as the boundary values between them. The equivalence classes for the metro fare system are:

• Before 9:30 am (full fare)
• Between 9:30 am and 5:00 pm (saver ticket)
• Between 5:00 pm and 7:00 pm (full fare)
• After 7:00 pm (saver ticket)

The boundary values are 9:30 am, 5:00 pm, and 7:00 pm. Therefore, the test set that provides the best equivalence partitioning coverage is the one that includes one value from each equivalence class and the boundary values, which is option D. References =

This is an effective method to employ business users in your testing effort because it allows them to leverage their domain knowledge and experience without requiring them to have technical skills or testing tools. Test charters are high-level descriptions of the test objectives, scope, and approach that guide the testers to explore the system and report any issues they find. Test charters are flexible and can be adapted to different test levels and types. They are also suitable for the V-model development lifecycle, which emphasizes verification and validation at each stage of the development process1

The equivalence partitions are based on the size of the carpet purchase and the installation price. There are four possible sizes: small, medium, large, and extra large. There are three possible prices: $5, $4, and $2 per square yard. The smallest set of test conditions that covers all the equivalence partitions is to test each size with its corresponding price, plus a no purchase scenario. Option C is the only one that does that. Option A does not test the large and extra large sizes. Option B does not test the extra large size. Option D tests more than the minimum required. References = ISTQB Certified Tester Advanced Level Syllabus Technical Test Analyst, page 50, section 4.1.2.2.
