Automatic Generation of Test Cases From Activity Diagrams for Uml Based Testing (Ubt)

Abstract

Activity diagrams are one of UML behavioural models suitable for system testing because it has the capacity to effectively describe the behaviours of systems under development. In this paper, a technique is proposed that generates test cases from activity diagrams by constructing an activity flow tree (AFT) which stores all the information extracted from the model file of the diagram through the help of a parser. Then, we applied an algorithm to generate test cases from the constructed tree. Test cases were generated based on the elements of activity diagrams such as activity sequences, associated descriptions and conditions. The proposed technique generated accurate test cases that completely tallied with the modeled requirements in the diagram. We utilized all-paths, basic pair paths, conditions, branches and transition criteria for generating test cases using ATM withdrawal operation software as a case study.

An Automated Test Case Generation Approach based on Activity Diagrams of SysML

“…Oluwatolani Oluwagbemi [16] constructed a new concept called activity flow tree (AFT) and it can store the information obtained by traversing the activity diagram. Then, AFT is used as an intermediate expression to generate test cases automatically.…”

Performance Analysis of Test Path Generation Techniques Based on Complex Activity Diagrams

“…The test path generation techniques from UML activity diagram usually depend on graph or tree theory: the test path generation techniques based on tree structure, such as the Dependent Flow Tree [3], the Fault Success Tree Analysis [4], and the Activity Tree [5]; the test path generation techniques based on graph structure, such as the Intermediate Black Box Model [6], the Activity Graph [7], the Activity Flow Table [8], the Activity Convert Grammar [9], the Activity Flow Graph [10], the Test Case Generation Based on Activity Diagram [11], the Activity Dependency Graph [12], and the Intermediate Testable Model [13]. In addition, the test path generation from UML activity diagram can be used the heuristic algorithm e.g., ant colony [14].…”

“…Currently, the advantages of the test path generation are applied to several real-world problems, for example, (1) to generate test data using the neighborhood search strategy [15] and using the genetic algorithm [16], (2) to generate test paths for effective chatbot software testing using customized response [17], (3) to optimize test cases by generating test path and selecting test data using Cuckoo search and Bee colony algorithm [18], and (4) to generate optimized test data for saving both testing cost and time [19].…”

TBFV-M: Testing Based Formal Verification for Sysml Activity Diagrams

“…Oluwatolani Oluwagbemi [19] proposed a new concept called activity ow tree (AFT) and it can store the information obtained by traversing the activity diagram. Then, AFT is used as an intermediate expression to generate test cases automatically.…”

“…These coverage criteria ensure the sufficiency of testing and provide implications for the test case generation algorithm. Here are four test coverage criteria used in our design, for test case generation of SysML activity diagram [19,25,26]:…”
