Test Code Quality and Its Relation to Issue Handling Performance

Automated testing is a basic principle of agile development. Its benefits include early defect detection, defect cause localization and removal of fear to apply changes to the code. Therefore, maintaining high quality test code is essential. This study introduces a model that assesses test code quality by combining source code metrics that...

Towards a catalog format for software metrics

In the past two decades both the industry and the research community have proposed hundreds of metrics to track software projects, evaluate quality or estimate effort. Unfortunately, it is not always clear which metric works best in a particular context. Even worse, for some metrics there is little evidence whether the metric measures the...

A Runtime Testability Metric for Dynamic High-Availability Component-based Systems

Runtime testing is emerging as the solution for the integration and assessment of highly dynamic, high availability software systems where traditional development-time integration testing cannot be performed. A prerequisite for runtime testing is the knowledge about to which extent the system can be tested safely while it is operational, i.e.,...

The prior statistics of object colors

The prior statistics of object colors is of much interest because extensive statistical investigations of reflectance spectra reveal highly non-uniform structure in color space common to several very different databases. This common structure is due to the visual system rather than to the statistics of environmental structure. Analysis involves...

Measuring the internet

The Internet is a collection of networks that use the TCP/IP suite of protocols. It has a huge impact on human activity. There are currently hundreds of millions of computers connected to the Internet, generating several petabytes traffic a day. Internet is still growing rapidly. However, the Internet today is not yet precisely characterized....
