End-to-end testing of applications across networks is enabled. To test the application and the infrastructure subsystems, an application server connected to the network contains an application under test. A response simulator is connected to the other end of the network. A test module is accessible to the application and to the simulator and contains a test message to be transmitted to the simulator, and an expected response message from the simulator. The application transmits each test message and compares a response message from the simulator to an expected response message. The simulator obtains the response to each test message from the test module.

Enabling end-to-end testing of applications across networks

The present invention discloses use of resource lists to invoke multiple services in an IMS environment. More specifically, SIP clients can exchange XML content with each other and/or with SIP servers that includes an XCAP resource list. A list entry can exist for each service that is to be included within a communication session. Each service specifying entry can include sub-attributes for the service, which comprise attribute-value pairs able to be read using standard conventions. Use of the resource lists alleviates a need to define a schema and write custom code each time a new service is developed. In one embodiment, additional nested XCAP resource lists can be used to define content that is to be shared among multiple services. For example, a resource list can be used to define a participant list, which is shared as common input data across the multiple services.

Invoking multiple SIP based services during a single communication session using resource lists

An apparatus, system, and method are disclosed for validating application server replication errors. The method includes receiving a first information message with a test sequence from a caller. The caller is engaged in a communication session with a callee according to a communication protocol and the communication session is managed by a first application server. The method also includes storing the test sequence in a replicable data structure on the first application server. The replicable data structure is replicated to a second application server to form a replicated data structure and both servers operate within an active-active configuration. The method also includes receiving a second information message from the caller. The second information message includes a confirmation sequence. In addition, the method includes determining a replication error in response to comparing the stored test sequence in the replicated data structure with the confirmation sequence.
