Comprehensive and Detailed Explanation From Exact Extract:

This is a classic application of theDecision Table Testingtechnique.

We are combining two conditions:

Purchase Volume, which has3 equivalence classes:

1 to 100 units → 0%

101 to 1000 units → 5%

More than 1000 units → 10%

Customer Type, which has2 categories:

Frequent Customer = YES → 5% extra

Frequent Customer = NO → 0%

This gives:

3 (bulk discount levels) × 2 (frequent customer options) = 6 unique decision rules

Each combination of these input conditions defines a separate test scenario with its own outcome.

“Decision table testing is used to identify the different combinations of inputs and their associated outputs. Each unique combination of input values defines a rule.”

(ISTQB CTFL Syllabus v4.0, Section 4.2.3 – Decision Table Testing, Page 40)

Thus,Option D (6 decision rules)is the correct answer.

Statement coverage strategyprioritizestest cases with higher statement coverage first, whileresolving dependenciesbefore execution.

TC60 (7%)has thehighest coveragebutdepends on REQ 1, so it should be executedafter its dependency is covered.

TC80 (6%)depends onREQ 2, so it should be prioritizedafter TC40 (REQ 2).

TC40 (5%)andTC90 (5%)should be executed early.

Lower coverage test cases (TC10, TC70, TC30, TC20) should come last.

Thus, the correct order is{TC 60; TC 80; TC 40; TC 90; TC 50; TC 10; TC 70; TC 30; TC 20} (D).

Checklist-based testing, as defined in the ISTQB CTFL syllabus, is indeed a review technique used within formal review processes. During these reviews, reviewers individually inspect work products to identify defects based on predefined checklists. These checklists serve as guidelines to ensure thorough examination and to cover important aspects consistently.

The other options do not accurately describe the checklist-based testing technique. Option A describes a technique for managing review meetings rather than the checklist-based testing itself. Option C incorrectly emphasizes the level of detail in checklists as a factor in reproducibility of test cases, which is not the primary focus of checklist-based testing. Option D, while true about the necessity of periodic review, is not the core aspect of the checklist-based testing technique itself.
