Software faults can be diagnosed using program spectra. The program spectra considered here provide information about which statements are executed in each one of a set of test cases. This information is used to compute a value for each statement which indicates how likely it is to be buggy, and the statements are ranked according to these values. We present two improvements to this method. First,...
We demonstrate the value analysis of Frama-C. Frama-C is an Open Source static analysis framework for the C language. In Frama-C, each static analysis technique, approach or idea can be implemented as a new plug-in, with the opportunity to obtain information from other plug-ins, and to leave the verification of difficult properties to yet other plug-ins. The new analysis may in turn provide access...
Parfait is a bug checker of C code that has been designed to address developers' requirements of scalability (support millions of lines of code in a reasonable amount of time), precision (report few false positives) and reporting of bugs that may be exploitable from a security vulnerability point of view. For large code bases, performance is at stake if the bug checking tool is to be integrated into...
Choosing the right test cases is an important task in software development due to high costs of software testing as well as the significance of software failures. Therefore, evaluating the quality of test techniques and test suites may help improving test results. Benchmarking has been successfully applied to various domains such as database performance. However, the difficulty in benchmarking test...
