Software debugging, testing, and verification

In commercial software development organizations, increased complexity of products, shortened development cycles, and higher customer expectations of quality have placed a major responsibility on the areas of software debugging, testing, and verification. As this issue of the IBM Systems Journal illustrates, there are exciting improvements in the underlying technology on all three fronts. Howev...

Software Testing Defect Prediction Model-a Practical Approach

Software defects prediction aims to reduce software testing efforts by guiding the testers through the defect classification of software systems. Defect predictors are widely used in many organizations to predict software defects in order to save time, improve quality, testing and for better planning of the resources to meet the timelines. The application of statistical software testing defect ...

First-class Concurrency Testing and Debugging

Unfortunately, the design of concurrent programs is a very challenging task. The main intellectual difficulty of concurrent programming lies in reasoning about the interaction between concurrently executing threads. Nondeterministic thread scheduling makes it extremely difficult to reproduce behavior from one run of a program to another. As a result, the process of testing and debugging concurr...
