Abstract

Software development life cycle (SDLC) depicts the distinct phases a software needs to go through, starting off with the requirement engineering phase through the testing phase. Requirement engineering and testing hold a very important place in the development of the software. Testing plays such a crucial part in SDLC that more than development some projects spend more time on testing. This helps in finding bugs and ensure that a quality product is shipped.

Test case generation is the toughest step in the testing process. It involves a lot of effort to find errors in the code. To eliminate the tedious process of finding errors in the code and improve the efficiency of the software, an innovative approach called Model-Based Testing (MBT) has been evolved. In the MBT approach, testing begins at the design phase and is thus helpful in identifying the faults early. Unified Modeling Language (UML) has been used to generate test cases using MBT. There has been a lot of research and proposals made for MBT using different UML diagrams. But the problem with these approaches is that a single UML diagram like activity diagram or sequence diagram is not enough to generate test cases in all the scenarios. There might be situation where multiple models might be used to generate test case. This paper discusses about different existing MBT methodologies used for testing and discusses the guidelines for choosing an efficient UML diagram to generate test cases. It also discusses about the way of improving the models by using multiple UML models or by extending the models.

Keywords: Software testing, Model-Based Testing (MBT), Unified Modeling Language (UML).
