A Study on Spectrum Based Fault Localization Techniques

Fault Localization or debugging is one of the major aspects when it comes to testing activity. In this criterion a fault is located and removed when a failure occurs during test. Many types of techniques were proposed before Spectrum-based Fault Localization (SFL) techniques was proposed in order to address the problem of fault localization, which point out program elements which have susceptibility of containing faults. In this article we will apply three different techniques to the different SBFL formulas. The two techniques are uniqueness and slicing. The third one is the combination of these two techniques. We will compare the efficiency and effectiveness of each of the technique on different Spectrum based Fault Localization techniques which will be applied on seven siemens suite programs
