+# ASTM NetRID DSS: Submitted ISA Validations test scenario
+
+## Overview
+
+Perform basic operations on a single DSS instance to create an ISA and query it during its time of applicability and
+after its time of applicability.
+
+## Resources
+
+### dss
+
+[`DSSInstanceResource`](../../../../../resources/astm/f3411/dss.py) to be tested in this scenario.
+
+### id_generator
+
+[`IDGeneratorResource`](../../../../../resources/interuss/id_generator.py) providing the ISA ID for this scenario.
+
+### isa
+
+[`ServiceAreaResource`](../../../../../resources/netrid/service_area.py) describing an ISA to be created.
+
+### problematically_big_area
+
+[`VerticesResource`](../../../../../resources/vertices.py) describing an area designed to be too big to be accepted by the DSS.
+
+## Setup test case
+
+### Ensure clean workspace test step
+
+This scenario creates an ISA with a known ID.  This step ensures that ISA does not exist before the start of the main
+part of the test.
+
+#### Successful ISA query check
+
+**[astm.f3411.v19.DSS0030](../../../../../requirements/astm/f3411/v19.md)** requires the implementation of the DSS endpoint enabling retrieval of information about a specific ISA; if the individual ISA cannot be retrieved and the error isn't a 404, then this requirement isn't met.
+
+#### Removed pre-existing ISA check
+
+If an ISA with the intended ID is already present in the DSS, it needs to be removed before proceeding with the test.  If that ISA cannot be deleted, then the **[astm.f3411.v19.DSS0030](../../../../../requirements/astm/f3411/v19.md)** requirement to implement the ISA deletion endpoint might not be met.
+
+#### Notified subscriber check
+
+When a pre-existing ISA needs to be deleted to ensure a clean workspace, any subscribers to ISAs in that area must be notified (as specified by the DSS).  If a notification cannot be delivered, then the **[astm.f3411.v19.NET0710](../../../../../requirements/astm/f3411/v19.md)** requirement to implement the POST ISAs endpoint isn't met.
+
+
+## ISA Validation test case
+
+### ISA Validation test step
+
+#### ISA huge area check
+
+Attempting to put a too large ISA should result in a 400.
+
+#### ISA empty vertices check
+
+An ISA with a empty `vertices` array in the `extents.spatial_volume.footprint` field of the ISA creation payload should not result in a successful submission.
+
+#### ISA start time in the past check
+
+The DSS must reject ISAs with start times in the past.
+
+#### ISA start time after end time check
+
+The DSS must reject ISAs for which the start time is after the end time.
+
+#### ISA vertices are valid check
+
+The DSS must reject ISAs with invalid vertices, such as vertices that have latitude or longitude outside meaningful ranges.
+
+#### ISA missing outline check
+
+If the outline polygon is missing from the `extents.spatial_volume.footprint` field in the payload of the ISA creation request,
+the DSS is expected to reject the request.
+
+#### ISA missing volume check
+
+If the outline polygon is missing from the `extents.spatial_volume` field in the payload of the ISA creation request,
+the DSS is expected to reject the request.
+
+#### ISA missing extents check
+
+If the `extents` field is missing from the payload of the ISA creation request,
+the DSS is expected to reject the request.
+
+## Cleanup
+
+The cleanup phase of this test scenario attempts to remove the ISA if the test ended prematurely.
+
+### Successful ISA query check
+
+**[astm.f3411.v19.DSS0030](../../../../../requirements/astm/f3411/v19.md)** requires the implementation of the DSS endpoint enabling retrieval of information about a specific ISA; if the individual ISA cannot be retrieved and the error isn't a 404, then this requirement isn't met.
+
+### Removed pre-existing ISA check
+
+If an ISA with the intended ID is still present in the DSS, it needs to be removed before exiting the test. If that ISA cannot be deleted, then the **[astm.f3411.v19.DSS0030](../../../../../requirements/astm/f3411/v19.md)** requirement to implement the ISA deletion endpoint might not be met.
+
+### Notified subscriber check
+
+When an ISA is deleted, subscribers must be notified. If a subscriber cannot be notified, that subscriber USS did not correctly implement "POST Identification Service Area" in **[astm.f3411.v19.NET0730](../../../../../requirements/astm/f3411/v19.md)**.

+# ASTM NetRID DSS: Submitted ISA Validations test scenario
+
+## Overview
+
+Perform basic operations on a single DSS instance to create an ISA and query it during its time of applicability and
+after its time of applicability.
+
+## Resources
+
+### dss
+
+[`DSSInstanceResource`](../../../../../resources/astm/f3411/dss.py) to be tested in this scenario.
+
+### id_generator
+
+[`IDGeneratorResource`](../../../../../resources/interuss/id_generator.py) providing the ISA ID for this scenario.
+
+### isa
+
+[`ServiceAreaResource`](../../../../../resources/netrid/service_area.py) describing an ISA to be created.
+
+### problematically_big_area
+
+[`VerticesResource`](../../../../../resources/vertices.py) describing an area designed to be too big to be accepted by the DSS.
+
+## Setup test case
+
+### Ensure clean workspace test step
+
+This scenario creates an ISA with a known ID.  This step ensures that ISA does not exist before the start of the main
+part of the test.
+
+#### Successful ISA query check
+
+**[astm.f3411.v22a.DSS0030](../../../../../requirements/astm/f3411/v22a.md)** requires the implementation of the DSS endpoint enabling retrieval of information about a specific ISA; if the individual ISA cannot be retrieved and the error isn't a 404, then this requirement isn't met.
+
+#### Removed pre-existing ISA check
+
+If an ISA with the intended ID is already present in the DSS, it needs to be removed before proceeding with the test.  If that ISA cannot be deleted, then the **[astm.f3411.v22a.DSS0030](../../../../../requirements/astm/f3411/v22a.md)** requirement to implement the ISA deletion endpoint might not be met.
+
+#### Notified subscriber check
+
+When a pre-existing ISA needs to be deleted to ensure a clean workspace, any subscribers to ISAs in that area must be notified (as specified by the DSS).  If a notification cannot be delivered, then the **[astm.f3411.v22a.NET0710](../../../../../requirements/astm/f3411/v22a.md)** requirement to implement the POST ISAs endpoint isn't met.
+
+
+## ISA Validation test case
+
+### ISA Validation test step
+
+#### ISA huge area check
+
+Attempting to put a too large ISA should result in a 400.
+
+#### ISA empty vertices check
+
+An ISA with a empty `vertices` array in the `extents.volume.outline_polygon` field of the ISA creation payload should not result in a successful submission.
+
+#### ISA start time in the past check
+
+The DSS must reject ISAs with start times in the past.
+
+#### ISA start time after end time check
+
+The DSS must reject ISAs for which the start time is after the end time.
+
+#### ISA vertices are valid check
+
+The DSS must reject ISAs with invalid vertices, such as vertices that have latitude or longitude outside meaningful ranges.
+
+#### ISA missing outline check
+
+If the outline polygon is missing from the `extents.volume.outline_polygon` field in the payload of the ISA creation request,
+the DSS is expected to reject the request.
+
+#### ISA missing volume check
+
+If the outline polygon is missing from the `extents.volume` field in the payload of the ISA creation request,
+the DSS is expected to reject the request.
+
+#### ISA missing extents check
+
+If the `extents` field is missing from the payload of the ISA creation request,
+the DSS is expected to reject the request.
+
+## Cleanup
+
+The cleanup phase of this test scenario attempts to remove the ISA if the test ended prematurely.
+
+### Successful ISA query check
+
+**[astm.f3411.v22a.DSS0030](../../../../../requirements/astm/f3411/v22a.md)** requires the implementation of the DSS endpoint enabling retrieval of information about a specific ISA; if the individual ISA cannot be retrieved and the error isn't a 404, then this requirement isn't met.
+
+### Removed pre-existing ISA check
+
+If an ISA with the intended ID is still present in the DSS, it needs to be removed before exiting the test. If that ISA cannot be deleted, then the **[astm.f3411.v22a.DSS0030](../../../../../requirements/astm/f3411/v22a.md)** requirement to implement the ISA deletion endpoint might not be met.
+
+### Notified subscriber check
+
+When an ISA is deleted, subscribers must be notified. If a subscriber cannot be notified, that subscriber USS did not correctly implement "POST Identification Service Area" in **[astm.f3411.v22a.NET0730](../../../../../requirements/astm/f3411/v22a.md)**.
