Requirements-based testing with defect taxonomies

In this paper we summarize requirements-based testing with defect taxonomies which seamlessly integrates defect taxonomies into the standard test process to improve the effectiveness and the efficiency of testing requirements. Defect taxonomies which consist of hierarchies of defect categories provide information about the distribution of faults and failures in a project. In practice, most defect taxonomies are only used for the a-posteriori allocation of testing resources to prioritize failures for debugging purposes. Requirements-based testing with defect taxonomies (RTDT), which has been defined and evaluated in several previous publications [FB12], [FB13a], [FB13b], [FB14a], [FB14c], [FBP14], exploits the full potential of defect taxonomies to control and improve all phases of the overall test process, i.e., test planning, design, execution and evaluation. Figure 1 summarizes the process steps and artifacts of RTDT. Requirements Specification Defect Taxonomy Defect Category of Beizer DC Description of DC Severity ... ... ... ... ... 4xxx .
