Abstract: An application testing system limits downtime during testing of complex applications. The application testing system facilitates switching in and out any desired version of any of the multiple application components that implement the application functionality. As a result, application test personnel may work quickly to find, debug, and test the complete application functionality, without causing significant periods of application unavailability.

Abstract: An application integration system includes multiple aspect task tracking. Such tracking may include an external identifier aspect of tracking tasks by highly configurable external identifiers. Another aspect, an error aspect, includes tracking errors that occur as the target systems attempt to execute tasks, and categorizing those errors into groups. The multiple aspect tracking provides detailed insight into the status of each task, helping to solve the technical problem of implementing orderly execution of complex product requests while maintaining a transparent view of execution status at each stage of task execution. The multiple aspect task tracking features also eliminate the burden of manually searching through complex log files to determine task status. Furthermore, the distinction of errors into groups facilitates customized handling of different types of errors. Accordingly, the system may implement different error resolution paradigms responsive to the error group assigned to an error.

Abstract: An application integration system greatly improves the configurability and efficiency of integration of multiple disparate applications, such as those found in telecommunications service provider architecture. The application integration system disassembles messages into component parts and dynamically rebuilds the component parts into a target message compatible with a target system. The application integration system employs a highly configurable configuration mechanism that can be modified on the fly and adapted to meet the requirements of any number of different applications that may need to communicate across the telecommunications service provider architecture.
