二、Explain those terminologies（共4小题，每小题10分，共40分）
1.What is software engineering?
Software engineering is an engineering discipline that is concerned with all aspects of software production.
Software engineers should adopt a systematic and organised approach to their work and use appropriate tools and techniques depending on the problem to be solved, the development constraints and the resources available.
2. What is System requirements?
system requirements are expanded versions of the user requirements that are used by software engineers as the starting point for the system design.
3.What are the attributes of good software?
The software should deliver the required functionality and performance to the user and should be maintainable, dependable and acceptable.
Maintainability
Software must evolve to meet changing needs;
Dependability
Software must be trustworthy;
Efficiency
Software should not make wasteful use of system resources;
Acceptability
Software must accepted by the users for which it was designed.
This means it must be understandable, usable and compatible with
other systems.
4. What is White-box Testing?
•Looking at the internal structure of a program and deriving test cases based on the logic or control flow.
•Test cases can be designed to reach every branch in the code and to exercise each condition
•Also known as:
–Structural Testing
–Glass-Box Testing
