An Approach to Modeling and Testing Web Applications Based on Use Cases

Abstract

In this work, large Web applications are modeled using hierarchical profile use-case diagrams called UCTMs (use case transition models) with the concept of LC (logical component). Based on proposed UCTM, a system-level testing method is implemented through transferring the textual description of use cases into CDDs (constraint directed diagrams). The CSC (constraint scenario coverage) criterion is proposed. Test cases generated from CDD can satisfy CSC criterion and avoid the problem of combinatorial explosion. When individual use case test scenarios are available, they can be synthesized into system tests according to the sequences of use cases in hierarchical UCTM.
