Answer(s): B

Which of the following comparisons of component testing and system testing are TRUE?

Component testing verifies the functioning of software modules, program objects, and classes that are separately testable, whereas system testing verifies interfaces between components and interactions with different parts of the system.
Test cases for component testing are usually derived from component specifications, design specifications, or data models, whereas test cases for system testing are usually derived from requirement specifications, functional specifications or use cases.
Component testing focuses on functional characteristics, whereas system testing focuses on functional and non-functional characteristics.
Component testing is the responsibility of the technical testers, whereas system testing typically is the responsibility of the users of the system.

Answer(s): B

Which of the following statements BEST describes the difference between testing and debugging?

Testing pinpoints (identifies the source of) the defects. Debugging analyzes the faults and proposes prevention activities.
Dynamic testing shows failures caused by defects. Debugging finds, analyzes, and removes the causes of failures in the software.
Testing removes faults. Debugging identifies the causes of failures.
Dynamic testing prevents causes of failures. Debugging removes the failures.

Answer(s): B

Which of the following statements BEST describes one of the seven key principles of software testing?

Automated tests are better than manual tests for avoiding the Exhaustive Testing.
Exhaustive testing is, with sufficient effort and tool support, feasible for all software.
It is normally impossible to test all input / output combinations for a software system.
The purpose of testing is to demonstrate the absence of defects. The purpose of testing is to demonstrate the absence of defects.
