8.2: Software Test Strategies
Each major software development activity should have a plan. For small projects, a single project-level plan could incorporate each major activity. For large projects, a major activity, especially an activity that occurs in every phase, will have its own plan, such as a software V&V (verification and validation) plan or software test plan. Such plans contain management or technical topics, including goals of the activity, strategies, processes, procedures, techniques, or tools. The next section addresses test quality goals, strategies, processes, and techniques, and the next addresses test strategies in more detail.
Unlike physical systems, most of the defects in software are design errors. Read about the important purpose of software testing and differentiate between verification and validation and basic software testing terms. Compare and contrast various testing strategies, including black-box, white-box, top-down, and bottom-up.
In this section, you will learn about two kinds of test strategies: how the logic is tested (via black-box and white-box testing) and how the testing is conducted (by top-down and bottom-up testing).
