+# ASTM F3548-21 notifications requirement
+
+While ASTM F3548-21 does not specifically prohibit sending notifications for operational intent changes when those notifications were not specifically prescribed by a notification that an operational intent may be relevant to a subscription (response from the DSS), InterUSS expects that notifications will only be sent at these particular times.
+SCD0085 requirement states only a positive requirement (preconditions satisified => notification must be sent).
+It doesn't establish a negative requirement (preconditions not satisfied => no notifications may be sent).
+As these negative requirements are reasonable  and related to SCD0085, interUSS has added it as a requirement for testing.
+This can happen in following situations -
+* <tt>NoDssEntityNoNotification</tt> If a USS was unable to write an entity reference to the DSS, it should not erroneously notify that operational intent, to another USS subscribed in the area.
+* <tt>NoSubscriptionNoNotification</tt> If a USS wrote an entity reference to the DSS, and was notified of no other USS subscription, then it should not send a notification to any USS. So the USS  shall (OnlyPrescribedNotifications) only send operational intent notifications when prescribed by SCD0085.

+# Data Validation of GET operational intents by USS test scenario
+
+## Description
+This test checks that the USS being tested validates the operational intents received as response to its GET request from another USS.
+Control_uss which is a mock uss plans a nearby V-shaped operation, and provides the data that tested_uss GETs.
+tested_uss validates the GET response from control_uss and accordingly plan its operation.
+Notably the following requirements:
+
+- **[astm.f3548.v21.SCD0035](../../../../requirements/astm/f3548/v21.md)**
+
+## Resources
+### flight_intents
+FlightIntentsResource provides the two V-shaped flight intents.
+The convex hulls of the 2D footprints of the two flights intersect, but the polygons do not intersect.
+There is an overlap in time and altitude of the two flights.
+- flight_1
+- flight_2
+
+### control_uss
+MockUSSResource that will be used for planning flights, controlling data shared for validation testing, and gathering interuss interactions from mock_uss.
+
+### tested_uss
+FlightPlannerResource that will be used for the USS being tested for its data validation of operational intent.
+
+### dss
+DSSInstanceResource that provides access to a DSS instance where flight creation/sharing can be verified.
+
+## Setup test case
+### Check for flight planning readiness test step
+Both USSs are queried for their readiness to ensure this test can proceed.
+
+#### Flight planning USS not ready check
+If either USS does not respond appropriately to the endpoint queried to determine readiness, this check will fail and the USS will have failed to meet **[astm.f3548.v21.GEN0310](../../../../requirements/astm/f3548/v21.md)** as the USS does not support the InterUSS implementation of that requirement.
+
+### Area clearing test step
+Both USSs are requested to remove all flights from the area under test.
+
+#### Area cleared successfully check
+**[interuss.automated_testing.flight_planning.ClearArea](../../../../requirements/interuss/automated_testing/flight_planning.md)**
+
+## Successfully plan flight near an existing flight test case
+
+### [Control_uss plans flight 2 test step](../../../flight_planning/plan_flight_intent.md)
+Flight 2 should be successfully planned by the control USS.
+
+### [Validate flight 2 sharing test step](../validate_shared_operational_intent.md)
+Validate that flight 2 is planned
+
+### Precondition - check tested_uss has no subscription in flight 2 area test step
+In order to run this test scenario, we need tested_uss to trigger GET operational intent request to mock_uss.
+So we need to make sure that there is no subscription of tested_uss, that would trigger notification of flight 2 to tested_uss.
+No notification pushed by control_uss to tested_uss, will ensure that tested_uss will make a GET request to control_uss for flight 2 details,
+while planning a nearby flight.
+If a notification is sent to tested_uss, the precondition for running this scenario will not be satisfied.
+
+### [Tested_uss plans flight 1 test step](../../../flight_planning/plan_flight_intent.md)
+The test driver attempts to plan flight 1 via the tested USS. It checks if any conflicts with flight 2
+which is of equal priority and came first.
+
+### [Validate flight 1 sharing test step](../validate_shared_operational_intent.md)
+Validate flight 1 is planned.
+
+### [Validate flight2 GET interaction test step](test_steps/validate_get_operational_intent.md)
+Validate that tested_uss makes a GET request for obtaining details of flight 2 from control_uss.
+In a previous step (Precondition - check tested_uss has no subscription in flight 2 area), we ensured that no notification of flight 2 was sent to tested_uss.
+Hence, tested_uss will need to make a GET request to obtain flight 2 details.
+
+### [Validate flight1 Notification sent to Control_uss test step](test_steps/validate_notification_operational_intent.md)
+Tested_uss notifies flight 1 to Control_uss, due to its subscription through flight 2.
+
+### [Delete tested_uss flight test step](../../../flight_planning/delete_flight_intent.md)
+Teardown
+
+### [Delete control_uss flight test step](../../../flight_planning/delete_flight_intent.md)
+Teardown
+
+## Flight planning prevented due to invalid data sharing test case
+### [Control_uss plans flight 2, sharing invalid operational intent data test step](../../../flight_planning/plan_flight_intent.md)
+Flight 2 should be successfully planned by the control_uss.
+The control_uss, which is mock_uss is instructed to share invalid data with other USS, for negative test.
+
+### [Validate flight 2 shared operational intent with invalid data test step](test_steps/validate_sharing_operational_intent_but_with_invalid_interuss_data.md)
+Validate that flight 2 is shared with invalid data as a modified behavior is injected by uss_qualifier for a negative test.
+
+### Precondition - check tested_uss has no subscription in flight 2 area test step
+In order to run this test scenario, we need tested_uss to trigger GET operational intent request to mock_uss.
+So we need to make sure that there is no subscription of tested_uss, that would trigger notification of flight 2 to tested_uss.
+No notification pushed by control_uss to tested_uss, will ensure that tested_uss will make a GET request to control_uss for flight 2 details,
+while planning a nearby flight.
+If a notification is sent to tested_uss, the precondition for running this scenario will not be satisfied.
+
+### [Test_uss attempts to plan flight 1, expect failure test step](test_steps/plan_flight_intent_expect_failed.md)
+The test driver attempts to plan the flight 1 via the tested_uss. It checks if any conflicts with flight 2
+which is of equal priority and came first.
+
+### [Validate flight 1 not shared by tested_uss test step](../validate_not_shared_operational_intent.md)
+Validate flight 1 is not shared with DSS, as plan failed.
+
+### [Validate flight 2 GET interaction test step](test_steps/validate_get_operational_intent.md)
+Validate that tested_uss makes a GET request for obtaining details of flight 2 from control_uss.
+In a previous step (Precondition - check tested_uss has no subscription in flight 2 area), we ensured that no notification of flight 2 was sent to tested_uss.
+Hence, tested_uss will need to make a GET request to obtain flight 2 details.

+# Plan flight Expect Failed test step
+
+This page describes the content of a common test case where a valid user flight intent fails in a flight planner, because of invalid data shared for a nearby flight shared by another USS.  See `plan_flight_intent_expect_failed` in invalid_op_test_steps.py.
+
+## Plan should fail check
+
+A USS shouldn't go ahead and plan if it doesn't have accurate information.
+As per SCD0035 a USS needs to verify a particular conflict status.
+If flight intent data shared for a nearby flight shared is invalid, the USS can't successfully perform that verification.
+It couldn't have obtained valid information about the other operational intents it's supposed to verify that conflict status against.
+Therefore, the USS should fail an attempt to plan. If the plan succeeds, we know they've violated SCD0035 because they failed to verify that particular conflict status.
