Abstract

Some networked applications are based on more than one communication protocol, such as UDP, TCP and RMI, and must be carefully tested under communication faults. If the emulation of a fault that affects message exchanging does not take into account all simultaneously used protocols, the behavior emulated in an experiment can be different from that observed under real fault occurrence. This paper presents Comform, a communication fault injector for multi-protocol Java applications. It works at JVM level, intercepting protocol messages, and, in some cases, it also operates at the operating system level, using firewall rules. The approach is useful for both white box and black box testing and preserves the target application’s source code.
