STILE: A Tool for Parallel Execution of E2E Web Test Scripts

Description

Automated end-to-end (E2E) Web testing relying on frameworks such as Selenium Web Driver is commonly used to assess the quality of web applications. However, the resulting test scripts may require long execution times, due to their interaction with the browser GUI and backend services. To avoid repeated and costly setup of the Web application state, testers tend to build test suites whose test scripts depend on each other (i.e., one test case sets up the application state expected by another test case). In this paper we present Stile, a tool for the parallel execution of Web test scripts that ensures the compliance of all execution schedules with the dependencies among the involved test scripts, while at the same time minimizing the execution time and the computation time required for such parallel execution. Experimental results show that execution times can be approximately halved thanks to Stile.
