Invoking Test Service Operations
After you have selected the service operation to test and have set up the integration metadata, you can invoke the test service operation.
When you invoke an asynchronous service operation type, for example, asynchronous one-way, asynchronous request-response, or asynchronous-to-synchronous, the system invokes the service operation using the Publish method.
When you invoke a synchronous service operation type, the system invokes the service operation using the SyncRequest method.
To invoke a service operation in the Service Operation Tester:
Access the Service Operation Tester page ().
Click the Invoke Operation button.
