Pesticide Paradox is due to
- A.
Debugging
- B.
Repeated execution of the same tests
- C.
Fixing the defects
- D.
Removing failure causes
Correct Answer
B. Repeated execution of the same testsExplanation
The Pesticide Paradox refers to the phenomenon where a set of test cases that initially find bugs become ineffective over time, as they are not updated or modified. This happens because the same tests are repeatedly executed without any changes, leading to a decrease in their effectiveness in finding new defects. As the system evolves and changes, the existing tests may not cover the new functionality or scenarios, resulting in undetected bugs. Therefore, the Pesticide Paradox is caused by the repeated execution of the same tests without updating or adding new tests to ensure comprehensive test coverage.Rate this question:
