22. Given the following code, which statement is true about the minimum number of test cases required for full statement and branch coverage? Read p Read q IF p+q > 100 THEN Print “Large” ENDIF IF p > 50 THEN Print “p Large” ENDIF
-
A) 1 test for statement coverage, 3 for branch coverage
-
B) 1 test for statement coverage, 2 for branch coverage
-
C) 1 test for statement coverage, 1 for branch coverage
-
D) 2 tests for statement coverage, 2 for branch coverage
Correct Answer
A. B) 1 test for statement coverage, 2 for branch coverageExplanation
The code has two IF statements, so at least two test cases are required for branch coverage. However, the second IF statement is nested inside the first one, so it will only be executed if the condition of the first IF statement is true. Therefore, only one test case is needed to cover both statements. This is why the minimum number of test cases required for full statement and branch coverage is 1 for statement coverage and 2 for branch coverage.Rate this question:
