A test team consistently finds between 90% and 95% of the defects present in the system under test. While the test manager understands that this is a good defect-detection percentage for her test team and industry, senior management and executives remain disappointed in the test group, saying that the test team misses too many bugs. Given that the users are generally happy with the system and that the failures which have occurred have generally been low impact, which of the following testing principles is most likely to help the test manager explain to these managers and executives why some defects are likely to be missed?

A.

A. Exhaustive testing is impossible
B.

B. Defect clustering
C.

C. Pesticide paradox
D.

D. Absence-of-errors fallacy

Correct Answer
A. A. Exhaustive testing is impossible

Explanation
The correct answer is "a. Exhaustive testing is impossible". This principle states that it is not possible to test every possible combination of inputs and conditions in a system. Even with a high defect-detection percentage, it is unrealistic to expect the test team to find every single bug. This principle helps the test manager explain to the managers and executives that no matter how thorough the testing is, some defects are likely to be missed.

B.

B. Test principles only affect test execution activi ties.
C.

C. Test principles affect the early test activities such as review.
D.

D. Test principles affect activities throughout the test life cycle.

Correct Answer
D. D. Test principles affect activities throughout the test life cycle.

Explanation
Test principles are guidelines or fundamental beliefs that guide the testing process. They provide a framework for making decisions and conducting testing activities effectively. The correct answer is d. Test principles affect activities throughout the test life cycle, which means that these principles are applicable from the early test activities such as review, through the preparation for testing, test execution activities, and all the way to the end of the test life cycle. Test principles help ensure consistency and quality in testing by providing guidance for all stages of the testing process.

_____________ of the usability of a component may be done during component testing.

A.

A. Acceptance Testing
B.

B. System Testing
C.

C. Integration Testing
D.

D. Performance Testing

Correct Answer
A. A. Acceptance Testing

Explanation
Acceptance testing is the process of evaluating a component or system's compliance with specified requirements and determining whether it is acceptable for delivery to the end user. This type of testing is typically performed to validate that the component meets the user's expectations and requirements. Therefore, it is the most appropriate type of testing to assess the usability of a component during component testing. System testing focuses on testing the entire system, integration testing focuses on testing the interaction between different components, and performance testing focuses on evaluating the performance characteristics of the system, none of which directly address usability.
