dsTest, Developing Solutions, HTTP Interface, HTTP SmartFlow, HTTP Testing

Developing Solutions provides a HTTP SmartFlow feature with its dsTest suite of network testing software products.  With this feature, you can use XML messaging over HTTP to test GET, PUT, POST, DELETE, and Result transaction initiators and responders.  Using our SmartFlow feature, you create simple to complex transaction flows between the device under test (DUT) and the dsTest simulator nodes, including message definitions and state machine elements.

HTTP SmartFlow is intended for exchanging structured information in a decentralized, distributed environment.  It extends HTTP for XML messaging, and defines an extensible messaging framework independent of implementation specific semantics.

With SmartFlow, your HTTP flows between the DUT and the dsTest simulator nodes are made by including message definitions and state machine elements.  dsTest, Developing Solutions, HTTP, HTTP SmartFlow, dsClient GUIThe SmartFlow state machine contains a unique list of states that a HTTP message flow can traverse, allowing the definition of different paths for success, failure, or other conditions, all defined within the state machine.  When defining a message template it is only necessary to include and provision the elements whose values will be compared to information in a received message.  Multiple handlers can be used with different templates of the same message type in order to execute various actions or state changes depending on the composition or content of a received message.

The dsClient GUI can be used to create the message defintions and state machine(s) easily.

Implementation

The dsTest HTTP SmartFlow feature allows the simulator nodes to provide the following events toward the DUT:

  • HTTP Get – Retrieve data
  • HTTP Put – Retrieve data
  • HTTP Post – Send data to be processed
  • HTTP Delete – Mark data for deletion
  • HTTP Result – HTTP response with status code

HTTP message payloads include:

  • Fill – insert number of bytes into payload
  • File – data contents of file is inserted into payload
  • User Data – transparent data in inserted into payload

A complete set of events that can be generated with the HTTP SmartFlow application can be found here.

As with all dsTest products, the node  configurations and test scenarios are easily defined and configured with XML files that are validated against a published XML Schema to avoid invalid definitions.  With our dsClient GUI, you can create, run, and archive tests, capture, graph and archive operational measurements, capture real-time data flows, and manage your dsTest servers and testing scenarios with a standalone application that runs on your PC.

Operational Measurements (OMs)

A comprehensive set of Operational Measurements for the HTTP SmartFlow feature is available via dsClient CLI or dsClient GUI.
