Systematic Literature Review on Test Case Quality Characteristics and Metrics

Companies are constantly optimizing their processes to increase the efficiency of software development, which heavily depends on software testing to fulfil stringent business requirements and with high-quality software released. The detection of software defects and the assurance of software quality are facilitated by high-quality test cases. However, the current metrics used to measure test case quality (TCQ) lack clarity. Therefore, this study aims to address this gap by identifying metrics and the corresponding characteristics that measure the TCQ. This paper presents a systematic literature review (SLR) focused on TCQ characteristics and metrics. By analyzing empirical papers published between 2010 and June 2018, a total of 23 papers were identified for inclusion in the review. Through this process, 16 characteristics and 50 metrics were identified. These characteristics and metrics were further analyzed, categorized, and finalized as the evaluation metrics for TCQ characteristics. The outcomes of this study contribute to the development of a comprehensive model for assessing TCQ.
