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).

Test analysis involves identifying the features to be tested and deriving test conditions. It is the phase where testers analyze the test basis (e.g., requirements, specifications) to identify testable aspects of the system. Test design (A) focuses on creating test cases, test implementation (C) involves preparing the test environment, and test execution (D) runs the tests.

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.
