| # ASTM SCD DSS: Availability Arbitration test scenario | ||
|
|
||
| ## Overview | ||
|
|
||
| Ensures that a DSS properly enforces limitations on created subscriptions | ||
|
|
||
| ## Resources | ||
|
|
||
| ### dss | ||
|
|
||
| [`DSSInstanceResource`](../../../../resources/astm/f3548/v21/dss.py) to be tested in this scenario. | ||
|
|
||
| ## DSS Report test case | ||
|
|
||
| This test attempts to submit to the DSS a report about a communication issue with a USS that might otherwise go unnoticed. | ||
| A dummy `getOperationalIntentDetails` query is made to a non-existent USS in order to produce a realistic report, as if a USS was not reachable when trying to retrieve one of its operational intent. | ||
|
|
||
| ### Make valid DSS report test step | ||
|
|
||
| #### [Make report to DSS](../make_dss_report.md) | ||
|

| ## USS Availability test case | ||
