An application under test may be run in a test mode that receives a series of test scenarios and produces a set of test results under the control of a verification application. The verification application utilizes “typed-data” (i.e., data having known types that are associated with the data itself, e.g., XML-based data) such that a number of parameters can be set for each event and a number of result parameters can be checked for each result in at least one script. A series of scripts can be combined into an action file that may invoke scripts and override parameters within the invoked scripts. The events can be sent and received using a number of messaging protocols and communications adapters.
