Abstract: Certain example embodiments described herein relate to approaches for testing client reactions to simulated disruptions in a real production environment that leverages the publish/subscribe messaging model (or one of its variants), optionally in connection with JMS messages and/or triggers. In certain example embodiments, a test driver reads a script that includes an instruction flow that brings down brokers in a broker cluster similar to (or in a manner as inflicted by) broker crashes (e.g., where a process or application does not have a chance to save its state or data before it is terminated), and/or broker stop/start events, e.g., to simulate the problems and determine whether the client application remains intact in the presence of errors. The simulations may leverage hardware and/or software means for intentionally causing disruptions in a live production environment. Thus, it advantageously becomes possible to test an application integration's client-side failover and/or load-balancing implementations.
