Across the three executions, every reachable statement is exercised except statements 22, 27, 28, and 29. None of the supplied combinations of price, quantity, bonus, and market causes execution to enter the branches containing those statements.

The tests collectively execute eight distinct numbered statements: 1, 2, 4, 5, 6, 7, 8, and 10. Of the ten numbered statements, this yields statement coverage of 8/10, or 80%.

A good level of code comments improves understandability and makes software easier to analyze and change, contributing especially to maintainability.

Multiple condition testing covers all possible combinations of the atomic conditions in each decision. Consequently, it subsumes the coverage objectives of less rigorous statement, decision, and condition/decision approaches, providing the highest coverage level listed.

Nesting level in a code fragment is determined by counting how many control structures (loops, if-statements) are embedded one inside another, starting the count from the outermost structure. A code fragment consisting of one conditional or loop nested inside another outer control structure has two nesting levels — the outer structure being level one and the structure embedded within it being level two — which is the standard way nesting depth is assessed for control-flow-based test design and coverage analysis in the ISTQB syllabus.
