An architecture for a computing environment wherein transactions preferably model the enterprise and its business processes directly, allowing third-party systems, like ERP, supply chain and Web portals, to be more loosely coupled. Because the system will often be distributed throughout the enterprise, reliance on central critical servers is reduced. The system of the present invention can also fill-in gaps in the functionality of legacy systems, as well as invoke complex applications and direct automated systems. The system offers an architecture where users can model their particular enterprises in business terms so that disparate applications can be linked without custom programming.

An automated software testing and validation system allows testing of a software application under test (SAUT) regardless of the dynamic nature of the SAUT. An abstracted set of hierarchal or linear objects model certain regions of the SAUT. Automated test scripts utilize theses regions to intuitively navigate and identify potions of the SAUT to automate. The scripts can also access specific SAUT elements contain within each defined region. These elements can then be used to invoke actions or verify outputs there from. The system uses a set of rich identification rules embodied in the system which allow the user to configure the identification of any element within the abstracted region. The rules are customizable to allow the user to configure the desired level of loose coupling between the automated scripts and the target element to adapt the scripts to the nature of the SAUT.

A system and method that facilitate secure communication employing dialog session keys that can be shifted unilaterally is provided. A key exchange key can further be employed to encrypt and / or decrypt the dialog session keys that are used to encrypt and / or decrypt message(s) that form a dialog between services. For example, the key exchange key can be unique to a service pair, while a first dialog session key is unique to message(s) originated by a first service, and, a second dialog session key is unique to message(s) originated by a second service. The system allows the dialog session keys to be independently managed by each endpoint (e.g., service).

A system for automatically implementing high-level instructions in a distributed application program, where the high-level instructions reflect the behavior of the distributed application program, includes at least a tools component. The tools component is used to write high-level instructions in the form of declarative models, and place them in a repository. An executive component then receives the declarative models from the repository and refines them (e.g., via progressive elaboration) until there are no ambiguities. A platform-specific driver then translates the commands from the executive component, effectively turning the declarative model instructions into a set of imperative actions to be implemented in one or more application containers. The platform-specific driver also relays one or more event streams to an analytics means, which can result in modifications to the declarative models and corresponding new sets of instructions coming through the platform-specific driver at a later point.
