The following diagram displays the logical dependencies between requirements and the individual requirement priorities. For example, 'R2->R3' means that R3 is dependent on R2. Priority is indicated by the number next to the letter ''P' i.e. P1 has a higher priority than P2. Which one of the following options best describes the test execution sequence using both requirement dependency and priority
A financial institution is to implement a system that calculates the interest rates paid on investment accounts based on the sum invested. You are responsible for testing the system and decide to use equivalence partitioning and boundary value analysis to design test cases. The requirements describe the following expectations: Investment range | Interest rate R500 to RIO 000 10% RIO 001 to R50 000 11% R50 001 to RlOOOOO 12% RIOOOOl to R500 000 | 13% What is the minimum number of test cases required to cover all valid equivalence partitions for calculating the interest?

Which of the following statements best describes the way in which decision coverage is measured?

A.
Measured as the number of statements executed by the tests, divided by the total number of executable statements in the code.
Answers
A.
Measured as the number of statements executed by the tests, divided by the total number of executable statements in the code.
B.
Measured as the number of lines of code executed by the tests, divided by the total number of lines of code in the test object.
Answers
B.
Measured as the number of lines of code executed by the tests, divided by the total number of lines of code in the test object.
C.
Measured as the number of decision outcomes executed by the tests, divided by the total number of decision outcomes in the test object.
Answers
C.
Measured as the number of decision outcomes executed by the tests, divided by the total number of decision outcomes in the test object.
D.
It is not possible to accurately measure decision coverage.
Answers
D.
It is not possible to accurately measure decision coverage.
Suggested answer: C

Explanation:

Decision coverage, also known as branch coverage, is measured as the number of decision outcomes executed by the tests divided by the total number of decision outcomes in the test object. It ensures that every possible branch (true/false) decision in the code has been executed at least once.
