JN Test Suite Platform: XML Script Examples for Different Protocols

The test logic for a particular test is presented as a state machine containing states and transitions between the states.

A typical scenario where JN Test Suite is used for service prototyping includes:

  • entering a state and sending a service request towards the tested service
  • waiting for inbound events associated with service response
  • checking the received service response and moving to another state, or to the end of the test
  • repeating the steps listed above

A typical scenario where JN Test Suite is used for service prototyping includes:

  • entering a state and waiting for inbound events associated with an indication sent by the tested service
  • checking the received service indication and moving to another state, or to the end of the test
  • entering another state and sending a service response towards the tested service
  • repeating the steps listed above

State Chart XML notation

State Chart XML (SCXML) syntax is applied for describing the state machine associated with a test. It is an open standard introduced by World Wide Web Consortium (W3C), http://www.w3.org/TR/scxml/

SCXML syntax contains standard XML tags representing the state machine concepts (states, transitions, etc.). JN Test Suite adds custom XML tags for representing communications protocol messages, operations and parameters, for example:

<isup:iam> <sccp:destination_address> <map2:update_location> <cap2:initial_dp>
<sip:invoke> <diameter:ccr> ... etc.

JN Test Suite interprets the XML scripts and produces the associated protocol specific messaging behind the custom tags.

JN Test Suite API provides functionality for automatic conversion of binary protocol messages to corresponding XML notation. For example, copy the binary message from Wireshark and paste it in JN Test Suite Console: the XML notation for this message will be returned.
