Software Quality Assurance Practice Exam

What does the specification for a module typically define?

1. Logic coverage

2. Input/Output parameters

3. Multi-condition criterion

4. Coverage criterion

The correct answer is: Input/Output parameters

The specification for a module typically defines the input and output parameters because it serves as a detailed description of what a module is expected to do within the system. This includes the types of data that will be received (input) and the types of data that will be produced (output), establishing a clear contract for the module's interactions with other components. In software development, understanding the input and output parameters is crucial for several reasons. It allows developers to know what data they need to provide when calling a module and what results to expect. This clarity helps in validating whether the module is functioning as intended and also assists in integration with other system components. Without a detailed specification of input and output parameters, it would be challenging to build, test, and maintain the module effectively, potentially leading to errors and miscommunications among development teams. Logic coverage, multi-condition criterion, and coverage criterion are terms related to testing strategies and metrics rather than specifications. They focus on how well tests can exercise various paths or conditions within the code rather than defining what the module should do. Thus, while they are important in the quality assurance process, they do not directly relate to the definitions provided in a module's specification.
