Test analysis answers 'what to test': it analyses the test basis, identifies testable features, defines and prioritises test conditions, and evaluates the test basis for defects. Test design answers 'how to test': it turns test conditions into test cases, identifies coverage items, defines test data requirements and designs the test environment. Example: the condition 'login with a locked account' becomes, in design, a case with exact inputs and the expected error message.
02
What changed in CTFL v4.0 compared with the 2018 syllabus?
v4.0 added Agile and DevOps content: the whole team approach, test-first approaches like TDD, ATDD and BDD, shift-left, retrospectives, collaboration-based test approaches, the test pyramid and testing quadrants. It renamed the pesticide paradox to 'tests wear out', removed use case testing and decision coverage, focused white-box testing on statement and branch coverage, and described test roles instead of job titles.
03
What is the difference between severity and priority?
Severity is the degree of impact the defect has on the system or its stakeholders, such as a crash or data loss. Priority is the urgency of fixing it, usually set by the business or product owner. Testers usually suggest severity, and priority is decided in triage. Example: a crash in a rarely used admin report is high severity but may be low priority.
04
A production hotfix must go live in three hours. How do you decide what to test?
I would do a quick impact analysis to see what the change touches, run confirmation tests for the defect, then a risk-based regression subset covering the changed module, its integrations and critical business flows like login and payment. I would use the automated smoke suite in the pipeline, record what was not covered, and plan fuller regression in the next regular release.
05
Explain collaborative user story writing, the 3 Cs and INVEST.
User stories are written collaboratively by business, development and testing. The 3 Cs are Card (the medium describing the story), Conversation (how the story will be used, documented or verbal) and Confirmation (the acceptance criteria). A good story follows INVEST: Independent, Negotiable, Valuable, Estimable, Small and Testable. If stakeholders cannot say how to test a story, it is probably unclear or does not reflect real value.
06
Your organisation is moving from the V-model to DevOps. How should the test strategy change?
I would push component tests and static analysis into the pipeline on every commit, build a test pyramid with many unit tests, fewer API tests and few UI tests, provision environments through infrastructure as code and add production monitoring. Testers shift from long test phases to continuous risk analysis, exploratory testing and quality coaching. I would plan training and track metrics like lead time and escaped defects.
07
Order these tests for execution: A (priority 1, depends on C), B (priority 2), C (priority 3), D (priority 2, depends on B). 1 is highest.
A has the highest priority but depends on C, so C must run first, followed by A. Next come the priority 2 tests: B, then D, because D depends on B. The execution order is C, A, B, D. ISTQB exams often include such questions; always satisfy dependencies first, then follow priority, and run the highest priority test as early as its dependencies allow.
08
Why is early and frequent stakeholder feedback important?
Early and frequent feedback catches misunderstandings about requirements before they become expensive. Without it, the product may not match what stakeholders want, leading to costly rework, missed deadlines, blame games and even project failure. Regular feedback through reviews, demos and backlog refinement keeps the team focused on the most valuable features and builds a shared understanding of what is being built.
09
A field accepts integers from 1 to 99. Which set of values achieves 100 percent 2-value BVA coverage: {1, 99}, {0, 1, 99, 100}, {0, 50, 100} or {1, 2, 98, 99}?
The answer is {0, 1, 99, 100}. Two-value BVA needs each boundary value and its closest neighbour in the adjacent partition: 0 and 1 at the lower edge, 99 and 100 at the upper edge. {1, 99} misses the invalid neighbours, {0, 50, 100} misses 1 and 99, and {1, 2, 98, 99} stays inside the valid partition, which is closer to 3-value thinking.
10
Which good testing practices apply regardless of the SDLC model?
CTFL v4.0 lists these: for every software development activity there is a corresponding test activity; each test level has its own specific objectives; test analysis and design for a level begin during the corresponding development phase; and testers are involved in reviewing work products as soon as drafts are available. Together these practices support early testing and quality control in waterfall, V-model and Agile projects alike.
The quadrants group test types by whether they are business-facing or technology-facing, and whether they support the team or critique the product. Q1 (technology, support): component and component integration tests, usually automated. Q2 (business, support): functional tests, examples, user story tests, prototypes. Q3 (business, critique): exploratory, usability and user acceptance testing. Q4 (technology, critique): smoke tests and non-functional tests except usability, such as performance and security.
12
Derive test conditions for the requirement 'Users can transfer up to 50,000 rupees per day.'
Read the test basis and list testable aspects. Conditions: a transfer within the limit succeeds; a transfer of exactly 50,000 succeeds; a transfer above 50,000 is rejected with a clear message; several transfers in one day are added together against the limit; the limit resets the next day; zero or negative amounts are rejected. Prioritise them by risk, then design test cases with exact amounts using boundary value analysis.
13
Describe a situation where a developer rejected your defect. How did you handle it?
Situation: a developer marked my defect 'works as designed'. Task: resolve it without conflict. Action: I re-read the user story, attached the acceptance criteria that contradicted the behaviour, and discussed it calmly with the developer and product owner, focusing on user impact rather than blame. Result: the product owner confirmed it was a defect, and we clarified the story wording so similar confusion did not happen again.
14
Why does CTFL v4.0 recommend starting non-functional testing early?
Non-functional tests are often left to the end, but late discovery of performance or security problems can threaten the whole project. v4.0 recommends starting early, even at component level, for example measuring response time of a key service. Some tests need special environments such as a usability lab. Many non-functional tests reuse functional tests but measure a different quality, like checking login speed under 500 concurrent users.
15
A review meeting turns into people blaming the author. How do you handle it as moderator?
I would refocus the discussion on the work product, not the person, remind everyone of the review objectives, and record the anomaly neutrally. Afterwards I would speak privately with the people involved. To prevent repeats, I would set ground rules, train participants and make sure review results are never used to judge individuals. Authors in a safe culture share work openly, so reviews find more defects.
16
Find the minimum tests for 100 percent statement and branch coverage of this code.
read(x)
if x > 10:
print('big')
print('done')
Statement coverage: one test with x = 15 executes every statement, so 1 test.
Branch coverage: the if has a true and a false outcome, so tests with x = 15 and x = 5 are needed, 2 tests.
17
You have three years of testing experience and three weeks to prepare for CTFL. How do you plan?
Experience helps, but the exam follows syllabus wording, not company practice. Week 1: read chapters 1 to 3 and the glossary terms in each learning objective. Week 2: study chapters 4 to 6, practise BVA, decision tables, state transitions, coverage and estimation calculations. Week 3: take timed official sample exams, analyse every wrong answer against the syllabus, and revise weak chapters.
18
Tell me about a time a review you did prevented a serious problem.
Situation: reviewing a refund user story, I noticed it did not say how partial refunds work on discounted orders. Task: clarify it before development started. Action: I logged the gap, set up a 15-minute call with the product owner and developer, and we added three acceptance criteria with worked examples. Result: the feature shipped without the refund calculation errors that had hurt an earlier release.
19
Write a test charter for an exploratory session on a checkout page.
Charter: Explore the checkout page with different coupon and payment combinations to discover pricing and rounding errors. Time box: 60 minutes. Focus areas: coupon stacking, expired coupons, quantity changes after applying a coupon, currency rounding, and using the browser back button. Record test ideas, defects, questions and areas covered. Debrief with the test lead after the session to agree next charters.
In the whole team approach, any team member with the right knowledge can perform any task, and everyone is responsible for quality. The team shares a physical or virtual workspace, and testers work closely with business representatives to create acceptance tests and with developers to agree the test strategy and automation. It improves communication and uses combined skills, although safety-critical contexts may still need higher test independence.
21
Which test estimation techniques are described in CTFL v4.0?
Estimation based on ratios uses historical figures, such as a development-to-test effort ratio. Extrapolation uses measurements from the current project, for example averaging the last three iterations. Wideband Delphi is an expert-based technique where experts estimate separately and iterate until consensus; Planning Poker is an Agile variant. Three-point estimation uses optimistic, most likely and pessimistic values to calculate a weighted estimate and its standard deviation.
Functional testing checks what the system should do, covering completeness, correctness and appropriateness. Non-functional testing checks how well it behaves, using ISO/IEC 25010 characteristics such as performance efficiency, usability, security, reliability, compatibility, maintainability and portability. Black-box testing is specification-based, and white-box testing is structure-based. Any test type can be applied at any test level, with a different focus at each.
23
Calculate a three-point estimate where optimistic is 6, most likely is 9 and pessimistic is 18 person-days.
Situation: a ticket booking app had passed all scripted tests. Task: run a one-hour exploratory session on seat selection. Action: I tried quick double taps, switching networks and booking the same seat from two devices. Result: two users could book the same seat. I logged a detailed report with videos, it was fixed before release, and concurrency tests were added to the regression suite.
25
How do you use the ISTQB glossary to prepare effectively?
Each learning objective lists keywords that you must know. Make flashcards for them with the exact glossary definition and one example from your own work, such as 'test basis: the user story for checkout'. Review them daily with spaced repetition. Pay attention to similar terms, like test condition versus test case, and confirmation versus regression testing, because exams use them as distractors.
26
What is branch testing and how is branch coverage measured?
A branch is a transfer of control between two nodes in the control flow graph. Branches can be unconditional, like straight-line code, or conditional, like the true and false outcomes of an if or the cases of a switch. Branch coverage = branches exercised / total branches x 100. Branch testing designs tests so that every branch, including the hidden false path of an if without else, is exercised.
27
An order can be placed, shipped, delivered, cancelled or returned. How would you test this workflow?
State transition testing fits because behaviour depends on the current state and events. I would draw the diagram, for example placed to shipped, shipped to delivered, placed to cancelled, delivered to returned, and build a state table. Tests cover every valid transition and attempt invalid ones, such as cancelling a delivered order or returning an undelivered one, checking the system rejects them correctly.
28
Free shipping applies for orders of 499 rupees or more, otherwise a fee of 40 applies. Design tests using EP and BVA.
Partitions: 0 or less is invalid, 1 to 498 pays 40, and 499 or more ships free. EP tests: 0 rejected, 250 pays 40, 800 free. 2-value BVA adds 0 and 1 at the lower edge and 498 and 499 at the free shipping boundary. Combined minimal set: 0, 1, 250, 498, 499 and 800, each with the expected fee clearly stated.
29
Why does 100 percent branch coverage guarantee 100 percent statement coverage, but not the other way round?
Every statement lies on at least one branch, so exercising all branches executes all statements. The reverse fails when a decision has an empty outcome. Example: 'if x > 10: print(big)' followed by 'print(done)'. One test with x = 15 runs every statement, giving 100 percent statement coverage, but the false branch is never taken, so branch coverage is only 50 percent. This is called subsumption.
All three are test-first approaches. In TDD, developers write a failing unit test, write code to pass it, then refactor. In ATDD, acceptance tests are derived from acceptance criteria with the team and business before development starts. In BDD, desired behaviour is written as Given/When/Then scenarios in natural language that stakeholders understand and that can be turned into executable tests. All three support shift-left.
31
What is the difference between a test progress report and a test completion report?
A test progress report is produced regularly during testing, for example daily or per sprint. It covers the period, progress against plan, impediments, metrics, new or changed risks and planned work. A test completion report is prepared at the end of a test level, iteration or project. It summarises testing, evaluates quality against the plan, lists deviations, unmitigated risks, open defects, metrics and lessons learned.
32
Your company is migrating customer data from a legacy system to the cloud. What testing is needed?
This is maintenance testing triggered by migration. I would check data completeness with record counts and checksums, data accuracy through sampling and reconciliation reports, transformation rules, performance on the new platform and rollback procedures. Operational acceptance testing covers backup, restore and failover. Regression testing of key functions on migrated data is needed, and retiring the old system may need archiving tests.
33
The requirements are incomplete and release is in two days. How do you test?
I would use session-based exploratory testing. I would write short charters for the riskiest areas, agree priorities with the product owner, run time-boxed sessions, note defects and questions, and debrief after each session. I would add error guessing for common failure types and a quick checklist for critical flows, and report clearly which areas were covered and which risks remain.
34
Your manager asks you to lower the severity of a defect to meet release targets. How do you respond?
Situation: before a release, my manager wanted a payment defect marked minor. Task: stay honest without creating conflict. Action: I explained the actual impact with data, how often it occurred and affected users, and suggested keeping severity accurate while lowering priority if the business accepted the risk, with a workaround documented. Result: the manager agreed, and the risk was recorded transparently.
35
A new tester has no domain knowledge and no detailed test cases. How can checklists help, and what is the risk?
A checklist of high-level conditions, such as validations, error messages, navigation and security basics, gives the new tester structure and consistency while learning the domain. Each run can vary slightly, which increases coverage. The risk is that checklists wear out as developers learn to avoid listed defects, so the team should update them with new defect patterns and pair the tester with an experienced colleague.
Unrealistic expectations about what a tool can do; inaccurate estimates of the time, cost and effort to introduce and maintain it; using a tool where manual testing is better; relying on the tool too much and ignoring critical thinking; dependency on the tool vendor, which may go out of business or retire the tool; open-source tools being abandoned; and tools not compatible with the development platform or not meeting regulations.
