1 According to the psychological principles of testing, who should perform the 'debugging' (pinpointing and correcting faults) of a unit?
1. The original programmer who wrote the module
2. A peer programmer who did not write the module
3. The independent SQA unit head
4. The moderator of the code inspection team

2 In unit testing, what is the primary function of a 'driver' module?
1. To represent the subordinate modules called by the unit under test
2. To record errors found in the Software Test Report (STR)
3. To transmit values/test cases to the module under test and display the results
4. To ensure the code complies with standard coding style and instructions
- View Answer
3 Who is generally responsible for organizing and carrying out unit testing?
1. The customer's quality assurance team
2. The software development team
3. An independent external testing organization
4. The project's end users during the run-in period
- View Answer
4 Why is unit testing considered to be 'largely white-box oriented'?
1. Because it ignores the internal logic and focuses only on external inputs
2. Because it is performed by an independent testing agency rather than the developers
3. Because as entities become larger (like whole programs), white-box testing becomes less feasible
4. Because it is exclusively derived from user requirements without looking at code

5 In non-incremental (big-bang) unit testing, what is the role of a 'stub' module?
1. To transmit test case values to the module under test
2. To provide a framework for generating random input samples
3. To simulate the function of a module that is called by the module under test
4. To display and compare actual results with expected results
- View Answer
6 What two types of information are required for designing effective unit test cases?
1. User manuals and project budgets
2. Hardware configurations and network connectivity logs
3. The module's source code and its functional or interface specification
4. Customer satisfaction surveys and regression test results
- View Answer
7 Which of the following is identified as a motivation for performing unit/module testing before testing the entire system?
1. It eliminates the need for any subsequent integration or system testing
2. It introduces parallelism by allowing multiple modules to be tested simultaneously
3. It is the only testing phase that does not require a functional specification
4. It is primarily used to prove that a module meets its intended requirements
- View Answer
8 According to the mapping of testing levels to software activities, unit testing assesses the software with respect to which phase?
1. Architectural Design
2. Detailed Design
3. Subsystem Design
4. Implementation
- View Answer
9 What is the primary objective of unit testing (also known as module testing) within the software development life cycle?
1. To assess the software with respect to the user's high-level requirements
2. To evaluate individual program units, such as procedures or methods, in isolation
3. To focus on the final assembly of the entire software package
4. To assess software with respect to the architectural design
