BH0-007 ISEB Intermediate Certificate in Software Testing — Practice Questions & TipsPassing the BH0-007 ISEB (now often referred to under ISTQB/BCS frameworks) Intermediate Certificate in Software Testing requires focused study, practical experience, and familiarity with the exam’s style of questions. This article provides a comprehensive guide: what the exam covers, study strategies, common question types, example practice questions with answers and explanations, and test-day tips to maximize your score.
What is the BH0-007 ISEB Intermediate Certificate in Software Testing?
The BH0-007 Intermediate Certificate is designed for testers who already have some hands-on experience and foundational knowledge of testing principles. It sits between the Foundation level and Advanced/Professional levels and aims to deepen understanding of test design techniques, test management concepts, risk-based testing, and the role of testing in the software lifecycle.
Target audience: testers with practical experience (typically 1–3 years), test analysts, QA engineers, team leads preparing to take on broader responsibilities, and anyone aiming to step up from the Foundation level.
Exam format (typical): multiple-choice and scenario-based questions, often including longer case-study items. Time and exact structure can vary by exam provider and version — confirm details on your exam registration page.
Key topic areas to master
- Test development lifecycle and the role of testing in software development models (waterfall, iterative, agile)
- Test planning and estimation
- Test design techniques: black-box (equivalence partitioning, boundary value analysis, state transition, decision tables), white-box (statement/branch coverage), and experience-based techniques
- Risk-based testing and prioritization
- Defect lifecycle, classification, and reporting
- Test tools and automation basics
- Test review techniques and reviews’ role in defect prevention
- Non-functional testing (performance, usability, security) at a practical level
- Test metrics and reporting
Study strategy and resources
-
Structured syllabus review
- Obtain the official syllabus or syllabus summary for BH0-007 and map topics to your study plan.
-
Use a layered approach
- Start with high-level concepts, then dive into specific test design techniques and practice applying them.
-
Practice with real scenarios
- Convert concepts into test cases for real or mock applications. Hands-on practice is essential.
-
Timed mock exams
- Simulate exam conditions to build speed and endurance. Review explanations after each mock to correct misunderstandings.
-
Join study groups or forums
- Discussing tricky scenario questions helps reveal alternative approaches and common pitfalls.
-
Use multiple resources
- Official syllabus, reputable textbooks on software testing, online courses, and past exam question banks.
How to approach exam questions
- Read each question carefully, underline key constraints or numerical limits.
- For scenario-based items, extract the system context and assumptions before answering.
- Manage time: allocate time per question and flag uncertain items for review.
- When using elimination on multiple-choice questions, cross out clearly wrong answers first.
- For questions on test design techniques, draw simple diagrams (state charts, decision tables) on scrap paper to visualize behavior.
Common pitfalls and how to avoid them
- Over-reliance on memorization: many questions test application of techniques, not rote facts.
- Skipping the syllabus: examiners stick to the syllabus; focus study there.
- Ignoring edge cases in boundary value analysis or state transitions.
- Poor time management—practice under timed conditions.
- Misinterpreting scenario constraints—re-read scenarios if unsure.
Practice questions (with answers and explanations)
Note: these examples mirror the style of intermediate-level items. Time yourself when practicing.
- A user-login screen accepts a username (1–20 chars) and a password (6–12 chars). Which of the following sets of test inputs best demonstrates boundary value analysis for the password field? A. 5, 6, 12, 13
B. “”, “abc”, “abcdef”, “abcdefghijkl”
C. 6, 7, 11, 12
D. Null, 6, 12, overflow
Answer: A. 5, 6, 12, 13
Explanation: Boundary value analysis selects values at, just below, and just above boundaries. For a 6–12 range: 5 (just below), 6 (boundary), 12 (boundary), 13 (just above).
- You are given a simple vending machine that accepts coins and dispenses products. A state transition test is required for selecting a product after inserting money. Which artefact is most useful to derive state transition test cases? A. Use case description
B. State transition diagram
C. Requirements glossary
D. Test plan
Answer: B. State transition diagram
Explanation: State transition diagrams explicitly show states, events, and transitions—ideal for deriving state-based test cases.
- During a review, a peer reports that a requirement is ambiguous: “The system shall process large files quickly.” Which activity should the reviewer recommend? A. Accept the requirement as-is and test performance later.
B. Raise a defect against the requirement and request clarification with measurable criteria.
C. Document in the test plan that performance is a non-functional concern.
D. Convert “quickly” to “as fast as possible” in test cases.
Answer: B. Raise a defect against the requirement and request clarification with measurable criteria.
Explanation: Ambiguous requirements must be clarified and made measurable (e.g., “process files under 1GB within 30 seconds”).
- A test team is estimating effort for regression testing. They choose a risk-based approach and identify high-risk areas that require daily regression cycles, medium-risk areas for weekly cycles, and low-risk for monthly. Which of the following best describes this approach? A. Exhaustive testing
B. Risk-based test prioritization
C. Exploratory testing
D. Static testing
Answer: B. Risk-based test prioritization
Explanation: Prioritizing test execution frequency by risk level is the essence of risk-based testing.
- A white-box test aims to achieve 100% branch coverage on a small function. Which technique is most appropriate to ensure branches are covered? A. Equivalence partitioning
B. Decision table testing
C. Control-flow-based test case design
D. Exploratory testing
Answer: C. Control-flow-based test case design
Explanation: Control-flow techniques (e.g., basis path testing) focus on executing different branches and paths in code.
Worked example: applying decision tables
Scenario: An insurance application issues quotes based on age and smoking status:
- If age < 25 and smoker → high premium
- If age < 25 and non-smoker → medium premium
- If age ≥ 25 and smoker → medium premium
- If age ≥ 25 and non-smoker → low premium
Construct a decision table, derive test cases covering each rule, then check for any combinations not applicable. Decision tables ensure you systematically cover rule combinations and spot gaps or contradictions.
Test automation tips for BH0-007
- Understand which tests are good candidates for automation: repeatable, stable, high ROI (e.g., regression, smoke).
- Keep automated tests maintainable: small, independent, descriptive names, and clear setup/teardown.
- Use data-driven approaches to reduce duplication.
- Track test flakiness and fix root causes rather than masking them.
- Integrate automated tests into CI pipelines to get fast feedback.
Metrics and reporting to know
- Test coverage (requirements or code-based)
- Defect density and defect discovery rate
- Test execution progress (passed/failed/blocked)
- Test case productivity (tests per timebox)
- Mean time to detect and fix defects
Use these metrics to provide succinct, objective status reports rather than large volumes of raw data.
Exam-day checklist
- Confirm exam location, time, ID requirements, and allowed materials.
- Bring necessary items: ID, authorised calculator (if permitted), pens/pencils.
- Rest well the night before; arrive early.
- Read questions carefully; flag and return to difficult ones.
- Manage time: if stuck, make a best-guess and move on.
Final preparation week plan (7 days)
- Day 1: Read syllabus and map weak areas.
- Day 2–3: Deep dive test design techniques with practice questions.
- Day 4: Study test management, risk-based testing, and reviews.
- Day 5: Take two timed mock exams; review mistakes.
- Day 6: Revisit weak topics, review cheat-sheets, and key definitions.
- Day 7: Light review, rest, and prepare logistics.
Passing BH0-007 requires both conceptual understanding and the ability to apply techniques to scenarios. Focus on practicing with scenario-based questions, mastering test design techniques, and managing your exam time effectively. Good luck.
