Review the request type, its inputs and output, and the request definition that selects the adapter flow that runs a test against an external system.

Request type

The spoke selector uses the Service Test Request as a contract between a test run and the adapter flow that runs it. The contract requires the plugin com.sn_appss. See Plugins installed with Service Test Management.

Name	Type	Description
Table Name (input)	String, up to 200 characters	The table of the record that the request is about. For a test run, the value is sn_st_mgmt_test.
Request Body (input)	JSON, up to 4,000 characters	The details of the test to run.
Response Body (output)	JSON, up to 4,000 characters	The response of the adapter flow.

The internal name of the request type is sn_st_mgmt_Service_Test_Request.

Request definition

A request definition connects a request type to an adapter. The application installs one request definition.

Field	Value
Name	Service Test Demo Request
Type	Service Test Request
Condition	Table Name is sn_st_mgmt_test
Adapter type	Flow
Adapter	STM test run demo adapter
Order	100
Pre-processor and post-processor	Both return their data unchanged.

The demo adapter simulates a result without an external system, so you can try the framework in a sandbox. To run tests against your own external system, you create a flow from the template and register it as the adapter. See Service Test Management automation framework.
