“…It can lead to false test conclusions if one first tests this application with a tool for Java applications based solely on UDP, like FIONA [5], and then tests it with a tool for Java applications based on TCP. To show the reason, Zorilla [1], a peer-to-peer middleware for executing supercomputing applications in grids, can be taken as an example target application.…”

Network applications with high dependability requirements must be carefully tested under communication faults to enhance confidence in proper behavior. Fault injection is very useful for these tests. When the applications use more than one protocol, such as UDP, TCP and RMI, a suitable tool that properly handles all of them is required. However, existing tools either are unable to test this kind of application or impose relevant drawbacks. This paper presents Comform, a communication fault injector for multi-protocol Java applications. It intercepts protocol messages at JVM level and uses firewall rules for fault emulation. The approach is useful for both white and black box testing and preserves the target's source code.

“…The fault case generation is commonly done randomly or by the Test Engineer (Benso et al, 2007;Chandra et al, 2007;Henry, 2009;Bernardi et al, 2012;Jacques-Silva et al, 2006;Lefever et al, 2004). These approaches are inadequate for the dependability testing of MapReduce systems because they disregard the internals of the fault tolerance mechanism, i.e., they ignore the behavior of fault recovery protocols regarding the different processing steps, e.g., they inject faults in some machines (fails 3 of 10) for some period (from 30 to 40 sec).…”

MapReduce systems have been widely used by several applications, from search engines to financial and commercial systems. There is considerable enthusiasm around MapReduce systems due to their simplicity and scalability. However, they lack a testing approach and framework ensuring their dependability. In this work, we propose a complete dependability testing solution for MapReduce systems. This solution is a model-based approach to generate representative fault cases, and a testing framework to automate their execution. Moreover, we introduce a new way to model distributed components using Petri Nets, and we show the promising results of the proposed testing framework, HadoopTest, on identifying faulty systems in real deployment scenarios.

System-S is a stream processing infrastructure which enables program fragments to be distributed and connected to form complex applications. There may be potentially tens of thousands of interdependent and heterogeneous program fragments running across thousands of nodes. While the scale and interconnection imply the need for automation to manage the program fragments, the need is intensified because the applications operate on live streaming data and thus need to be highly available. System-S has been designed with components that autonomically manage the program fragments, but the system components themselves are also susceptible to failures which can jeopardize the system and its applications.The work we present addresses the self healing nature of these management components in System-S. In particular, we show how one key component of System-S, the job management orchestrator, can be abruptly terminated and then recover without interrupting any of the running program fragments by reconciling with other autonomous system components. We also describe techniques that we have developed to validate that the system is able to autonomically respond to a wide variety of error conditions including the abrupt termination and recovery of key system components. Finally, we show the performance of the job management orchestrator recovery for a variety of workloads.
