System Testing and Test Plans

What is the main purpose of a test plan?

• A. To minimize errors and test all parts of the system.

• B. To document the programming code.

• C. To correct syntax errors in the system.

• D. To design the user interface of the system

Which type of test data checks inputs at their boundaries?

• A. Invalid test data

• B. Extreme test data

• C. Valid test data

• D. Random test data

Why is it nearly impossible to make a system completely error-free?

• A. Systems are tested only once.

• B. Programmers intentionally add errors.

• C. Complex systems can have multiple pathways and unexpected inputs.

• D. Testing does not involve users.

During black box testing, which of the following is NOT required?

• A. Knowledge of the system’s code and internal structure.

• B. Input data for testing system outputs.

• C. Expected outputs for comparison.

• D. Test plans for pathways.

Who typically performs white box testing?

• A. End-users

• B. Developers with knowledge of the internal structure

• C. Moderately skilled testers

• D. Automated testing tools only

Which of the following describes a limitation of black box testing?

• A. Requires coding skills to perform.

• B. Testers lack knowledge of boundary values and pathways.

• C. Cannot test user requirements.

• D. Requires highly skilled programmers.

What is the key difference between black box testing and white box testing?

• A. Black box testing focuses on code pathways, while white box testing checks user requirements.

• B. White box testing checks only outputs, while black box testing focuses on inputs.

• C. Black box testing requires no coding knowledge, while white box testing requires knowledge of the program's internal structure.

• D. Both methods test only small program modules.

Which statement about extreme test data is correct?

• A. It includes only valid inputs.

• B. It is data that tests the upper and lower limits of input values.

• C. It tests system outputs using real-world data.

• D. It cannot be used for boundary testing.

Why is it essential for a test plan to include all pathways through a system?

• A. To avoid unnecessary user involvement

• B. To ensure no part of the system is left untested, minimizing errors.

• C. To provide a structure for system documentation.

• D. To reduce the need for live data testing.
