Both positive and neagtive test cases can be derived from a single scenario. state true or false.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
This statement is true because a single scenario can be used to derive both positive and negative test cases. For example, if we have a scenario where a user is attempting to log in, a positive test case would be when the user enters the correct username and password and successfully logs in. On the other hand, a negative test case would be when the user enters an incorrect username or password and fails to log in. Therefore, a single scenario can be used to derive both positive and negative test cases.Rate this question:
