Software metrics plays an important role in measuring attributes that are critical to the success of a software project. Measurement of these attributes helps to make the characteristics and relationships between the attributes clearer. This in turn supports informed decision making. The field of software engineering is affected by infrequent, incomplete and inconsistent measurements. Software testing is an integral part of software development, providing opportunities for measurement of process attributes. The measurement of software testing process attributes enables the management to have better insight in to the software testing process. The aim of this thesis is to investigate the metric support for software test planning and test design processes. The study comprises of an extensive literature study and follows a methodical approach. This approach consists of two steps. The first step comprises of analyzing key phases in software testing life cycle, inputs required for starting the software test planning and design processes and metrics indicating the end of software test planning and test design processes. After establishing a basic understanding of the related concepts, the second step identifies the attributes of software test planning and test design processes including metric support for each of the identified attributes. The results of the literature survey showed that there are a number of different measurable attributes for software test planning and test design processes. The study partitioned these attributes in multiple categories for software test planning and test design processes. For each of these attributes, different existing measurements are studied. A consolidation of these measurements is presented in this thesis which is intended to provide an opportunity for management to consider improvement in these processes. / 00 92 51 4430327
