Software testing is sometimes plagued with intermittently failing tests and finding the root causes of such failing tests is often difficult. This problem has been widely studied at the unit testing level for open source software, but there has been far ...

Communication devices such as routers and switches play a critical role in the reliable functioning of embedded system networks. Dozens of such devices may be part of an embedded system network, and they need to be tested in conjunction with various ...

We have developed an interactive tool that predicts fault likelihood for the individual files of successive releases of large, long-lived, multi-developer software systems. Predictions are the result of a two-stage process: first, the extraction of ...

A key problem when doing automated fault analysis and fault prediction from information in a software change management database is how to determine which change reports represent software faults. In some change management systems, there is no simple ...

This research investigates ways of predicting which files would be most likely to contain large numbers of faults in the next release of a large industrial software system. Previous work involved making predictions using several different models ranging ...

We continue investigating the use of a negative binomial regression model to predict which files in a large industrial software system are most likely to contain many faults in the next release. A new empirical study is described whose subject is an ...

The ability to predict which files in a large software system are most likely to contain the largest numbers of faults in the next release can be a very valuable asset. To accomplish this, a negative binomial regression model using information from ...

A case study is presented using thirteen releases of a large industrial inventory tracking system. Several types of questions are addressed in this study. The first involved examining how faults are distributed over the different files. This included ...

Database systems play an important role in nearly every modern organization, yet relatively little research effort has focused on how to test them. This paper discusses issues arising in testing database systems and presents an approach to testing ...
