Event-driven software is very diverse, e.g., in form of Graphical User Interfaces (GUIs), Web applications, or embedded software. All EDS take sequences of events (e.g., messages and mouse-clicks) as input, change their state, and produce an output(e.g., events, system calls, and text messages) Regardless of the application, the challenges for testing event-driven software are similar. Most event-driven systems allow a huge number of possible event sequences, which makes exhaustive testing infeasible. In this paper, we propose several new test suite prioritization strategies for web-based applications and GUI applications. Further, examine whether these strategies can improve the rate of fault detection for web-based and GUI applications and their preexisting test suites. We prioritize test suites by test lengths, frequency of appearance of request sequences, and systematic coverage of parameter-values and their interactions. This paper extends the single model to generalized prioritization criteria that combine several criteria and result more effective test orders
