What is the purpose of a grey-box test case?
What is the purpose of a grey-box test case?
- To predict correct results on the interface
- To increase coverage metrics (correct)
- To ensure that the design meets the functionality intent
- To drive all permutations on the input lines
Why is full verification not practical on large pieces of designs?
Why is full verification not practical on large pieces of designs?
- Because it entails driving all permutations on the input lines (correct)
- Because it is intended to exercise significant features specific to the implementation
- Due to the difficulty in predicting correct results on the interface
- Because the principles of verification are not valid across all verification
How does a grey-box test case differ from a black-box test case?
How does a grey-box test case differ from a black-box test case?
- It drives all permutations on the input lines
- It predicts correct results on the interface without viewing internal signals
- It is written to increase coverage metrics (correct)
- It ensures that the design meets the functionality intent
