What is the value of statement coverage achieved by test case 1 from test set A? 2 credits [K3]

Statement coverage measures the percentage of executable statements in the source code that have been exercised by a test suite. To calculate this value for a specific test case, one must have access to the source code to determine the total number of executable statements and the details of the test case to trace its execution path. As these critical pieces of information are not provided in the question, a calculation cannot be performed, and no answer can be verified as correct.

The options A, B, C, and D represent specific coverage percentages. Without the source code and test case, there is no basis to confirm or deny any of these values. They are all unverifiable.

This section defines statement coverage as "the percentage of executable statements that have been exercised by a test suite."

This university-level textbook explains that calculating statement coverage requires analyzing the source code to identify statements and tracing test inputs to see which statements are executed.
