Generation of Test Cases from UML Diagrams - A Systematic Literature Review

Model-Based testing (MBT) is a technique to derive test cases from models of the system under test (SUT), and the UML is the leading and de-facto standard language for system models both in industry and academia. This paper describes the results of a general systematic literature review (SLR) on the topic of generating test cases based on UML diagrams. By using selection and exclusion criteria, 62 primary studies were chosen from 443 identified publications, which ranged from 1999 to 2019. This study analysed the approaches and outcomes of the reviewed papers. The analysis is mainly focused on the model type, intermediate formats used and coverage criteria. Based on the review results, research trends and deficiencies are identified, and future works are proposed.
