You can test any Service-Based Interface (SBI) in your 5G test network with dsTest‘s REST ServiceFlow application. You define the content of the messages sent as well as templates for the expected responses. Message content may include subscriber-specific information or information captured from a received message. Use the visual composer to define your transactions as you select message definitions by name. ServiceFlow is driven by events — either the receipt of a REST message or the receipt of a REST application event. The receipt of a specific application event can trigger a service consumer transaction (request sent/response received) or a service producer notification. Similarly, the receipt of a specific message can trigger a service producer transaction (request received/response sent).
REST ServiceFlow supports the following message types:
- GET — Retrieve data from the NF
- POST — Send data to the NF
- PUT — Update data at the NF
- DELETE — Delete data at the NF
- OPTIONS — Query the capabilities of an NF or the options/requirements associated with a resource
- Result — HTTP response with status code and, potentially, a JSON payload
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.
Advanced Testing Features
SmartEvents — Alter application behavior or coordinate multiple interface applications with SmartEvents. Our programmable, subscriber-level state machine gives you the ability to define handlers for specified application events that can then cause an event in another application to be executed. You can also configure handlers to modify subscriber information during run-time, introduce timers, or randomize subscriber behavior based on configurable probabilities to name a few of the many options in one of dsTest’s most powerful features.
SmartMessageElement — Insert, delete, or replace elements in Diameter, RADIUS, MAP, LDAP, GTP, REST, or SOAP messages with our SmartMessageElement solution. Define proprietary signaling or corrupt elements to facilitate negative testing. You can specify when your elements are used with SmartEvents.
Traffic Profile — Draw the shape of your test actions across time with Traffic Profile. You can define the rate for any action as a static rate or reference a Traffic Profile configuration, which also means that multiple Traffic Profiles can be running concurrently. Use Traffic Profile in conjunction with the randomizing features in SmartEvents to design a test that more truly simulates real-world network activity.
dsTest provides rich sets of measurements for REST ServiceFlow:
- Transaction and transport layer attempts, successes, and failures
- Transaction duration, transactions-per-second, and round-trip delay
- Message and byte counters
- Errors encountered and error indications received in messages
