Question
In the initial release of an insurance risk assignment application, a variety of test techniques were employed, especially equivalence partitioning. After a thorough root cause analysis of this release, it was determined that the developers tended to incorrectly use ">" and "<" rather than the ">=" and " <= " in the code at several decision points. This caused several borderline cases to be handled incorrectly. Based on this analysis, how would you modify your test strategy for the next version's release?
Options
- AUse the same approach, but schedule 50% more time for regression testing
- BCreate test cases using boundary value analysis techniques
- CRe-analyze the test basis and create a state transition diagram to ensure all transitions are
- DEnsure that decision tables are used throughout the testing process

Explanation
Boundary value analysis is a technique that focuses on testing the values at the boundaries of valid and invalid partitions. It is suitable for testing the errors caused by incorrect use of relational operators in the code, such as ">" and "<" instead of ">=" and "<=". By creating test cases using boundary value analysis, the tester can verify that the system handles the borderline cases correctly and does not miss any edge cases.
