20+ practice questions focused on Test Analysis and Design — one of the most tested topics on the ISTQB Certified Tester Foundation Level v4.0 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Test Analysis and Design PracticeAn e-commerce payment system applies a discount based on customer loyalty status (Standard, Silver, Gold) and purchase amount (Under $50, $50-$100, Over $100). How many test cases are required to achieve 100% boundary value analysis coverage using the 2-value boundary approach for the purchase amount variable?
Explanation: Boundary value analysis using the 2-value approach requires testing the minimum and maximum boundaries for each continuous partition. For the three purchase amount partitions, the boundaries are $0 (min), $50 (lower inner boundary), $100 (upper inner boundary), and the maximum realistic value. Multiplying these boundary values across the three loyalty categories ensures exhaustive numerical and categorical coverage.
An e-commerce system calculates shipping costs based on order weight: up to 5kg costs $5, over 5kg up to 20kg costs $10, and over 20kg costs $20. Applying Boundary Value Analysis (BVA) with the 2-value boundary approach, which set of test inputs represents the exact boundaries for this partition?
Explanation: The 2-value boundary approach requires testing the boundary value itself and its closest neighbor on the valid side of the partition. For the partition limits of 5kg and 20kg, the relevant boundary inputs are 5.0kg, 5.1kg, 20.0kg, and 20.1kg. Applying BVA ensures defects hiding at the exact threshold limits are effectively exposed, which is crucial for financial calculation accuracy.
An e-commerce system calculates shipping fees based on order weight: up to 5kg costs $5, over 5kg up to 20kg costs $10, and over 20kg up to 50kg costs $25. Weights above 50kg are rejected. Applying Boundary Value Analysis (BVA) with a 2-value strategy, which set of input values best tests the lower and upper boundaries of the second valid partition?
Explanation: Applying a 2-value boundary value analysis strategy requires testing the exact boundary and the immediate neighbor inside the partition for each boundary. For the second valid partition (5 to 20kg), the lower boundary is 5kg with its neighbor 5.1kg, and the upper boundary is 20kg with its neighbor 19.9kg. This thorough testing approach effectively uncovers off-by-one coding defects at the partition limits.
You are applying Equivalence Partitioning for a field that accepts a numeric score between 0 and 100 inclusive. Which set of values represents the best selection for partition testing?
Explanation: Selecting values from valid and invalid partitions ensures that both expected successes and error handling are verified. By picking a value from the valid range (e.g., 50) and one from each invalid range (e.g., -5 and 105), you test all logical branches of the input validation code. This strategy maximizes coverage while minimizing the number of test cases, which is essential for efficient test suite maintenance.
Refer to the exhibit. As a tester, what is your primary takeaway from this log during test design for future regression cycles?
Explanation: The log indicates a recurring instability in the database link, which persisted despite retries. During test design, you should incorporate this finding by creating a specific test condition to handle timeout scenarios gracefully. This allows you to verify that the application handles 'Database Unavailable' states without crashing, improving the robustness of the system design and ensuring that future releases can handle intermittent connectivity issues without catastrophic failure.

Start with 10 questions to gauge your current understanding of Test Analysis and Design. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Test Analysis and Design questions on the CTFL-v4 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Test Analysis and Design is tested as part of the ISTQB Certified Tester Foundation Level v4.0 blueprint. Practicing with targeted Test Analysis and Design questions ensures you can handle any format or difficulty that appears.
