Quality Factors of Test Cases: A Systematic Literature Review

The use of high quality test cases enable the detection of software defect which eventually helps in ensuring the quality of software before being released to end users. Unfortunately, at the moment, the criteria of good test cases are still vague without any specific model to measure the quality of the test cases. Therefore, this study aims to identify the criteria of good test cases based on the findings from studies conducted within the years 2010 to 2018. The Systematic Literature Review (SLR) by Kitchenham approach was adapted in order to comprehensively identify the related criteria. From the review, a total of 310 related articles were found from the IEEE Xplore, ACM Digital Library, and Science Direct databases. The search was then narrowed down using specific key-words and as a result the number relevant articles ended up to 14. From the review of these articles, 30 quality factors of the test cases were identified. These quality factors were further examined, categorized and finalized to be included as the quality factors of test cases evaluation metrics.
