A study of effective regression testing in practice

摘要: The purpose of regression testing is to ensure that changes made software, such as adding new features or modifying existing features, have not adversely affected the software should change. Regression usually performed by running some, all, test cases created modifications in previous versions software. Many techniques been reported on how select tests so number does grow too large evolves. Our proposed hybrid technique combines modification, minimization and prioritization-based selection using a list source code execution traces from run versions. This seeks identify representative subset all may result different output behavior version. We report our experience with tool called ATAC (Automatic Testing Analysis C) which implements this technique.
