Generating test sequences from UML use-case diagrams

Testing the software is an essential phase of the software development life-cycle. There are many ways to generate the test sequences, which are required to perform the testing tasks. UML use case diagrams describe the software specifications, which makes it one of the possible sources, which used to generate the test sequences. In this paper, UML use case diagrams are used to generate test sequences using a set of processes. As for the first process, the UML use case diagrams are converted to activity diagrams. The activity diagrams are used to make the use cases' relationships clear to cover all the paths in the testing. Then, the activity diagrams simplified by converting them to activity graphs, as preprocessing step of the test sequences' generation. The final process is to generate the test sequences by extracting the information from the activity graphs. The approach has been evaluated using three case studies and a comparison with other approaches from the prior work.
