Structural Unit Testing as a Service with PathCrawler-online.com

Path Crawler is a concolic test generation tool for the structural unit testing of C code. This paper describes the PathCrawler-online.com testing service. The user submits C source files and test parameters, and the server generates test-cases and coverage information. The service is mostly used today as a novel alternative to providing a demonstration version for students and potential users to install. However, Path Crawler-online can also be seen as a prototype for Testing as a Service and a first step towards Software Testing in the Cloud. In this spirit, we discuss the issues raised by our two-year experience with Path Crawler-online.
