+# ASTM SCD DSS: Implicit Subscription handling test scenario
+
+## Overview
+
+Checks that implicit subscriptions are properly created, mutated and cleaned up.
+
+## Resources
+
+### dss
+
+[`DSSInstanceResource`](../../../../resources/astm/f3548/v21/dss.py) to be tested in this scenario.
+
+### id_generator
+
+[`IDGeneratorResource`](../../../../resources/interuss/id_generator.py) providing the Subscription IDs for this scenario.
+
+### planning_area
+
+[`PlanningAreaResource`](../../../../resources/astm/f3548/v21/planning_area.py) describes the 3D volume in which subscriptions will be created.
+
+### utm_client_identity
+
+[`ClientIdentityResource`](../../../../resources/communications/client_identity.py) provides the identity that will be used to interact with the DSS.
+
+## Setup test case
+
+### [Ensure clean workspace test step](clean_workspace.md)
+
+This step ensures that no OIRs with the known test IDs exists in the DSS.
+
+## Single OIR implicit subscription is removed upon OIR deletion test case
+
+### Create an OIR with implicit subscription test step
+
+This step creates an OIR with an implicit subscription and confirms that the subscription can be queried
+
+#### [Create OIR](./fragments/oir/crud/create_query.md)
+
+#### [Valid Implicit Subscription](./fragments/sub/implicit_create.md)
+
+### Delete the OIR with implicit subscription test step
+
+#### [Delete OIR](./fragments/oir/crud/delete.md)
+
+#### 🛑 The implicit subscription was removed check
+
+Upon deletion of an OIR that is associated to an implicit subscription, if the subscription has no other
+associated OIRs, the DSS is expected to remove it.
+
+If a query attempting to fetch the implicit subscription succeeds, it implies that the implicit subscription has not
+been removed, and the DSS is in violation of **[astm.f3548.v21.DSS0005,1](../../../../requirements/astm/f3548/v21.md)**.
+
+#### 🛑 After removal of the only created OIR, subscriptions should be as before its creation check
+
+If, after the DSS is left in the same state as it was 'found' for an area, the subscriptions currently active do not correspond to the ones
+that were present when the test case started, the DSS may be failing to properly implement **[astm.f3548.v21.DSS0005,1](../../../../requirements/astm/f3548/v21.md)**
+or **[astm.f3548.v21.DSS0005,5](../../../../requirements/astm/f3548/v21.md)**.
+
+## Implicit subscriptions always properly cover their OIR test case
+
+This test case verifies that implicit subscriptions belonging to OIRs that are created, updated and deleted
+are properly managed.
+
+In particular, the scenario verifies that:
+ - implicit subscriptions attached to an OIR always correctly cover the OIR after it was created or mutated;
+ - implicit subscriptions are properly removed when they are no longer necessary.
+
+### Create an OIR with implicit subscription test step
+
+Create an OIR with which interactions will be tested and request an implicit
+subscription to be created.
+
+#### [Create OIR](./fragments/oir/crud/create_query.md)
+
+#### [Valid Implicit Subscription](./fragments/sub/implicit_create.md)
+
+### Create an overlapping OIR without any subscription test step
+
+This step creates an OIR in the `ACCEPTED` state that overlaps with the previously created OIR:
+it does not request the creation of an implicit subscription and does not attach the OIR to any subscription explicitly.
+
+This step expects that the implicit subscription from the previously created OIR is mentioned in the response's notifications,
+and that no new implicit subscription is created.
+
+#### [Create OIR](./fragments/oir/crud/create_query.md)
+
+#### 🛑 New OIR creation response contains previous implicit subscription to notify check
+
+If the newly created OIR does not mention the implicit subscription from the previous OIR in its notifications,
+the DSS is either improperly managing implicit subscriptions, or failing to report the subscriptions relevant to an OIR,
+and therefore in violation of **[astm.f3548.v21.DSS0005,1](../../../../requirements/astm/f3548/v21.md)** or **[astm.f3548.v21.DSS0005,5](../../../../requirements/astm/f3548/v21.md)** respectively.
+
+#### 🛑 No implicit subscription was attached check
+
+If the DSS attached an implicit subscription, by either creating or re-using an existing one, to the OIR that was created in this step,
+the DSS is in violation of **[astm.f3548.v21.DSS0005,1](../../../../requirements/astm/f3548/v21.md)**.
+
+### Mutate OIR with implicit subscription to not overlap anymore test step
+
+This step mutates the first OIR, which has an implicit subscription, to no longer overlap with the second OIR.
+
+The mutation request does not specify an existing subscription, and provides the parameters required for the creation of an implicit subscription.
+
+#### [Mutate OIR](./fragments/oir/crud/update_correct.md)
+
+#### 🛑 The implicit subscription can be queried check
+
+The implicit subscription attached to the mutated OIR should be able to be queried.
+
+If it cannot, the DSS is either improperly managing implicit subscriptions for OIRs, or failing to report the subscriptions relevant to an OIR,
+in which case the DSS is in violation of **[astm.f3548.v21.DSS0005,1](../../../../requirements/astm/f3548/v21.md)** or **[astm.f3548.v21.DSS0005,5](../../../../requirements/astm/f3548/v21.md)**, respectively.
+
+#### [Correct temporal bounds](fragments/sub/implicit_correct.md)
+
+#### 🛑 Non-mutated implicit subscription is deleted check
+
+If the DSS chose to create a new implicit subscription instead of updating the existing one, and the DSS did not remove the previous subscription,
+the DSS is in violation of either **[astm.f3548.v21.DSS0005,1](../../../../requirements/astm/f3548/v21.md)** or **[astm.f3548.v21.DSS0005,5](../../../../requirements/astm/f3548/v21.md)**.
+
+### Create an OIR overlapping with the second OIR but not the first test step
+
+This step creates a new OIR that only overlaps the OIR that has no implicit subscription,
+and expects to not have to notify any subscription related to the OIRs created in this scenario.
+
+#### [Create OIR](./fragments/oir/crud/create_query.md)
+
+#### 🛑 Within a temporal frame not overlapping a newly created implicit subscription, subscriptions should be the same as at the start of the test case check
+
+Within a geotemporal area that does not intersect with any of the implicit subscriptions that are left within the DSS,
+the subscriptions returned for an OIR created within said area should correspond to the ones
+that were present when the test case started.
+
+Otherwise, the DSS may be failing to properly implement **[astm.f3548.v21.DSS0005,1](../../../../requirements/astm/f3548/v21.md)**
+or **[astm.f3548.v21.DSS0005,5](../../../../requirements/astm/f3548/v21.md)**.
+
+#### 🛑 No implicit subscription was attached check
+
+If the DSS attached an implicit subscription, by either creating or re-using an existing one, to the OIR that was created in this step,
+the DSS is in violation of **[astm.f3548.v21.DSS0005,1](../../../../requirements/astm/f3548/v21.md)**.
+
+## Implicit subscriptions are properly deleted when required by OIR mutation test case
+
+This test case verifies that implicit subscriptions are properly removed if they become unnecessary following the mutation of an OIR.
+
+### [Ensure clean workspace test step](clean_workspace.md)
+
+This test step resets the workspace for this test case.
+
+### Create two OIRs with implicit subscription test step
+
+Creates two OIRs with an implicit subscription, which will then be replaced by an explicitly created subscription
+and deleted by an update that requests no subscription, respectively.
+
+#### [Create OIR](./fragments/oir/crud/create_query.md)
+
+#### [Valid Implicit Subscription](./fragments/sub/implicit_create.md)
+
+### Create a subscription test step
+
+This test step creates a subscription that will be used to replace the implicit subscription that was created for an OIR.
+
+#### [Create subscription](./fragments/sub/crud/create_query.md)
+
+Check creation succeeds and response is correct.
+
+### Update OIR with implicit subscription to use explicit subscription test step
+
+This step updates the OIR to use the subscription that was created in the previous step,
+and expects the previous implicit subscription to be removed.
+
+#### [Mutate OIR](./fragments/oir/crud/update_query.md)
+
+#### 🛑 Previously attached implicit subscription was deleted check
+
+If the implicit subscription that was attached to the OIR is still present after the OIR is updated to use another subscription,
+the DSS is failing to properly manage implicit subscriptions for OIRs, and is therefore in violation of **[astm.f3548.v21.DSS0005,1](../../../../requirements/astm/f3548/v21.md)**.
+
+### Update OIR with implicit subscription to use no subscription test step
+
+This step updates the OIR to not use any subscription, and expects the implicit subscription to be removed.
+
+#### [Mutate OIR](./fragments/oir/crud/update_query.md)
+
+#### 🛑 Previously attached implicit subscription was deleted check
+
+If the implicit subscription that was attached to the OIR is still present after the OIR is updated to use another subscription,
+the DSS is failing to properly manage implicit subscriptions for OIRs, and is therefore in violation of **[astm.f3548.v21.DSS0005,1](../../../../requirements/astm/f3548/v21.md)**.
