To answer this question, you need to understand test coverage criteria. Test coverage criteria refer to the extent to which a test suite or set of tests covers the requirements or components of a system. Let's go through each option to understand why it is correct or incorrect:
Option A) A measure of test coverage criteria is the percentage of user requirements covered. - This option is correct because one of the measures of test coverage criteria is indeed the percentage of user requirements covered. It helps determine how well the test suite covers the specified requirements.
Option B) Test coverage criteria can be measured in terms of items exercised by a test suite. - This option is incorrect because measuring test coverage criteria in terms of items exercised by a test suite is a valid approach. It helps assess the effectiveness of the tests in exercising the different components or functionalities of a system.
Option C) A measure of test coverage criteria is the percentage of faults found. - This option is correct because one of the measures of test coverage criteria is indeed the percentage of faults found. It helps evaluate how well the tests are able to detect faults or defects in the system.
Option D) Test coverage criteria are often used when specifying test completion criteria. - This option is correct because test coverage criteria are commonly used when determining test completion criteria. Test coverage criteria help define the minimum level of coverage that needs to be achieved before considering the testing phase complete.
The correct answer is Option B. This option is not true because test coverage criteria can indeed be measured in terms of items exercised by a test suite.
Therefore, the correct answer is B.
