测试知识问与答，第二期
Q: What is verification?
A: Verification ensures the product is designed to deliver all functionality to the customer; it typically involves reviews and meetings to evaluate documents, plans, code, requirements and specifications; this can be done with checklists, issues lists, walk-throughs and inspection meetings. You CAN learn to do verification, with little or no outside help.
Q: What is validation?
A: Validation ensures that functionality, as defined in requirements, is the intended behavior of the product; validation typically involves actual testing and takes place after verifications are completed.
Q: What is quality?
A: Quality software is software that is reasonably bug-free, delivered on time and within budget, meets requirements and expectations and is maintainable. However, quality is a subjective term. Quality depends on who the customer is and their overall influence in the scheme of things. Customers of a software development project include end-users, customer acceptance test engineers, testers, customer contract officers, customer management, the development organization’s management, test engineers, testers, salespeople, software engineers, stockholders and accountants. Each type of customer will have his or her own slant on quality. The accounting department might define quality in terms of profits, while an end-user might define quality as user friendly and bug free.
Q: What is software life cycle?
A: Software life cycle begins when a software product is first conceived and ends when it is no longer in use. It includes phases like initial concept, requirements analysis, functional design, internal design, documentation planning, test planning, coding, document preparation, integration, testing, maintenance, updates, re-testing and phase-out.
