To answer this question, you need to understand the purpose of test design techniques. Let's go through each option to understand why it is correct or incorrect:
Option A) Identifying test conditions only, not identifying test cases - This option is incorrect because test design techniques are used to identify both test conditions and test cases. Test conditions are the factors or variables that need to be tested, while test cases are the specific instances or scenarios that are designed to test those conditions.
Option B) Not identifying test conditions, identifying test cases only - This option is incorrect for the same reason as Option A. Test design techniques are used to identify both test conditions and test cases.
Option C) Identifying test conditions and identifying test cases - This option is correct because the purpose of test design techniques is to identify both test conditions and test cases. Test conditions are identified to ensure that all relevant factors are considered and tested, while test cases are designed to cover different scenarios and combinations of conditions.
Option D) Identifying test conditions or identifying test cases - This option is incorrect because the purpose of test design techniques is to identify both test conditions and test cases, not just one or the other.
The correct answer is C) Identifying test conditions and identifying test cases. This option is correct because test design techniques are used to identify both the factors to be tested (test conditions) and the specific instances or scenarios to test those factors (test cases).
