TAILIEUCHUNG - Lecture Software engineering - Chapter 4: Principles that guide practice

Software is tested to uncover errors that were made inadvertently as it was designed and constructed. But how do you conduct the tests? Should you develop a formal plan for your tests? Should you test the entire program as a whole or run tests only on a small part of it? Should you rerun tests you’ve already conducted as you add new components to a large system? When should you involve the customer? These and many other questions are answered when you develop a software testing strategy. | Chapter 4 Principles that Guide Practice Slide Set to accompany Software Engineering: A Practitioner’s Approach, 7/e by Roger S.

Software Engineering Knowledge You often hear people say that software development knowledge has a 3-year half-life: half of what you need to know today will be obsolete within 3 years. In the domain of technology-related knowledge, that’s probably about right. But there is another kind of software development knowledge—a kind that I think of as "software engineering principles"—that does not have a three-year .
