In this case, there are 2 possibilities for Condition-1, 3 possibilities for Condition-2, 2 possibilities for Condition-3, and 4 possibilities for Condition-4. There are also 2 possibilities for Action-1 and 2 possibilities for Action-2. Multiplying all these possibilities together gives us a total of 48 possible rules for the decision table.Rate this question:

Which of the following statements is true?
- A.
In state-transition testing, test cases are constructed from state/event combinations.
- B.
State-transition testing is a static test technique
- C.
In state-transition testing, the requirements are in the form of a task-event matrix
- D.
State-transition testing is a technique which uses a graphical representation of combinations of code control points and expected outputs.
Correct Answer
A. In state-transition testing, test cases are constructed from state/event combinations.Explanation
State-transition testing is a technique used to test systems that can be described as a finite number of states and transitions between those states. In this technique, test cases are constructed based on the different combinations of states and events that the system can undergo. By testing these state/event combinations, it is possible to verify if the system behaves correctly and transitions between states as expected. This approach helps to identify any defects or issues related to the system's state transitions.Rate this question:

An actor in use cases Select one:
- A.
Can be a person, another application , or an external system playing a role
- B.
Can pretend to do whatever it wants
- C.
Is different for each individual use case
- D.
Is a user or customer with in the system or application
Correct Answer
A. Can be a person, another application , or an external system playing a roleExplanation
The actor in use cases can be any entity that interacts with the system, whether it is a person, another application, or an external system. The actor plays a specific role in the use case scenario and can initiate actions or receive outputs from the system. The flexibility of the actor being able to play different roles allows for a versatile and adaptable use case model.Rate this question:

Use cases can serve as the foundation for creating: Select one:
- A.
Integration test cases
- B.
System and acceptance test cases
- C.
Conformance test cases
- D.
Unit Test cases
Correct Answer
B. System and acceptance test casesExplanation
Use cases can serve as the foundation for creating system and acceptance test cases because they describe the interactions between the system and its users. By analyzing the use cases, testers can identify the different scenarios and conditions that need to be tested during system and acceptance testing. Use cases provide a clear understanding of the system's functionality and help in designing test cases that cover all the possible user interactions and expected outcomes. Therefore, system and acceptance test cases can be derived from the use cases to ensure that the system meets the specified requirements and performs as expected.Rate this question:

Use cases are: Select one:
- A.
The sequential flow of messages from module (Unit) to module to implement a particular Use(Function)
- B.
A list of uses(functions) that the system provides
- C.
A screen diagram listing the functions that the system implements
- D.
Scenarios that describe the use of a system by an actor to accomplish a specific goal
Correct Answer
D. Scenarios that describe the use of a system by an actor to accomplish a specific goalExplanation
Scenarios that describe the use of a system by an actor to accomplish a specific goal provide a detailed description of how the system will be used in real-world situations. These scenarios outline the specific steps and interactions between the user (actor) and the system to achieve a desired outcome. They help in understanding the system's functionality, identifying potential issues, and ensuring that the system meets the user's needs.Rate this question:
