-Feature: Comprehensive AsyncResourceTracker Test Levels
-  As a developer
-  I want comprehensive test coverage for the async_cleanup module
-  So that all code paths are verified across 7 coverage levels
-
-  Background:
-    Given I have an async resource tracker
-
-  # ========================== LEVEL 1 — SMOKE TESTS ==========================
-
-  @smoke
-  Scenario Outline: Smoke — register and close a single valid resource via register/close_all
-    Given I have a mock async resource named "<resource_name>" that closes successfully
-    When I register the resource with name "<resource_name>"
-    And I close all tracked resources with timeout 30.0
-    Then the resource "<resource_name>" should be closed
-    And the tracker open_count should be zero
-
-    Examples:
-      | resource_name   |
-      | db-pool         |
-      | cache-conn      |
-      | file-handle     |
-
-  @smoke
-  Scenario Outline: Smoke — register None raises ValueError mentioning "resource"
-    When I try to register a <resource_type> resource with name "<name>"
-    Then a ValueError should be raised
-
-    Examples:
-      | resource_type | name        |
-      | None          | valid-res   |
-
-
-  # ========================== LEVEL 2 — REGISTRATION VALIDATION ==========================
-
-  @validation
-  Scenario: Registration — empty string name raises ValueError mentioning "name"
-    When I try to register a mock async resource with an empty string name
-    Then a ValueError should be raised mentioning "name"
-
-  @validation
-  Scenario: Registration — whitespace-only name is accepted (non-empty in Python)
-    When I register a mock async resource with name "<whitespace_name>"
-    Then no exception should be raised and open_count should be 1
-
-    Examples:
-      | whitespace_name |
-      | "   "           |
-      | "\t\n"          |
-
-  @validation
-  Scenario: Registration — duplicate name raises ValueError mentioning the name
-    Given I have a mock async resource named "dup-resource"
-    When I register the resource with name "dup-resource"
-    And I try to register another resource with the same name "dup-resource"
-    Then a ValueError should be raised mentioning "dup-resource"
-
-  @validation
-  Scenario: Registration — registering after close_all raises RuntimeError mentioning "closed"
-    Given I have a mock async resource named "pre-close-res"
-    When I register the resource with name "pre-close-res"
-    And I close all tracked resources
-    And I try to register a new resource named "post-close"
-    Then a RuntimeError should be raised mentioning "closed"
-
-  @validation
-  Scenario: Registration — multiple distinct resources can be registered concurrently
-    Given I have mock async resources named "res-1", "res-2", and "res-3"
-    When I register all three resources with their respective names
-    Then the tracker open_count should be 3
-
-
-  # ========================== LEVEL 3 — CONCURRENT/THREAD SAFETY ==========================
-
-  @concurrency
-  Scenario: Concurrency — multiple concurrent registrations are thread-safe
-    Given I have 5 mock async resources named "thread-res-1" through "thread-res-5"
-    When I register all five resources concurrently from different threads
-    Then the tracker open_count should be 5
-
-
-  # ========================== LEVEL 4 — TIMEOUT AND CANCELLATION HANDLING ==========================
-
-  @timeout
-  Scenario: Timeouts — resource exceeding timeout is logged and added to timed_out_resources
-    Given I have a mock async resource named "slow-resource" that takes 10 seconds to close
-    When I register the resource with name "slow-resource"
-    And I close all tracked resources with a 0.5 second timeout
-    Then the resource should be logged as timing out
-    And timed_out_resources should contain "slow-resource"
-
-  @timeout
-  Scenario: Timeouts — zero timeout causes immediate TimeoutError for slow resources
-    Given I have a mock async resource named "very-slow-res" that takes 5 seconds to close
-    When I register the resource with name "very-slow-res"
-    And I close all tracked resources with a 0.0 second timeout
-    Then timed_out_resources should contain "very-slow-res"
-
-  @timeout
-  Scenario: Timeouts — mixed scenario: some fast, some slow — only slow ones time out
-    Given I have 3 mock async resources:
-      | name          | close_delay_seconds |
-      | fast-1        | 0.0                 |
-      | fast-2        | 0.0                 |
-      | slow-resource | 5.0                 |
-    When I register all three resources
-    And I close all tracked resources with a 0.1 second timeout
-    Then fast-1 should be closed normally
-    And fast-2 should be closed normally
-    And timed_out_resources should contain "slow-resource"
-
-  @timeout
-  Scenario: Timeouts — resource closing exception is caught (not TimeoutError) and logged
-    Given I have a mock async resource named "error-resource" that raises ValueError on close
-    When I register the resource with name "error-resource"
-    And I close all tracked resources with a 30.0 second timeout
-    Then the tracker should handle the closing error without crashing
-    And exception details should be logged for "error-resource"
-
-  @timeout
-  Scenario: Timeouts — asyncio.CancelledError during close is caught and logged
-    Given I have a mock async resource named "cancelled-res" that raises CancelledError on close
-    When I register the resource with name "cancelled-res"
-    And I close all tracked resources with a 30.0 second timeout
-    Then the tracker should handle the cancellation without crashing
-    And exception details should be logged for "cancelled-res"
-
-  @timeout
-  Scenario: Timeouts — empty list of timed_out_resources after all resources close normally
-    Given I have a mock async resource named "fast-closer" that closes instantly
-    When I register the resource with name "fast-closer"
-    And I close all tracked resources with a 30.0 second timeout
-    Then timed_out_resources should be an empty list
-
-
-  # ========================== LEVEL 5 — IDIOMATIC CLOSE / IDEMPOTENCY ==========================
-
-  @idempotent
-  Scenario: Idempotency — calling close_all twice is safe and no-ops on second call
-    Given I have a mock async resource named "once-resource"
-    When I register the resource with name "once-resource"
-    And I close all tracked resources once
-    And I close all tracked resources a second time
-    Then the resource should be closed exactly once
-
-  @idempotent
-  Scenario: Idempotency — open_count is zero after double close_all
-    Given I have a mock async resource named "double-close-res"
-    When I register the resource with name "double-close-res"
-    And I close all tracked resources twice
-    Then the tracker open_count should be zero
-
-  @idempotent
-  Scenario: Idempotency — close_all on empty tracker is safe no-op
-    Given I have an async resource tracker with zero registered resources
-    When I close all tracked resources
-    Then no exception should be raised
-    And timed_out_resources should be an empty list
-
-
-  # ========================== LEVEL 6 — LEAK DETECTION / FINALIZER ==========================
-
-  @leak-detection
-  Scenario: Leak detection — __del__ warns when tracker still has open resources
-    Given I have a mock async resource named "leaky-conn"
-    And I register the resource with name "leaky-conn"
-    When the tracker is garbage collected without calling close_all
-    Then a leak warning should be logged mentioning "leaky-conn"
-
-  @leak-detection
-  Scenario: Leak detection — empty resources dict after close_all means no finalizer warning
-    Given I have a mock async resource named "properly-closed-res"
-    When I register the resource with name "properly-closed-res"
-    And I close all tracked resources
-    Then the tracker should report zero open resources on finalization and no leak warnings
-
-  @leak-detection
-  Scenario: Leak detection — partial leaks (some closed, some not) show individual warnings
-    Given I have a mock async resource named "closed-res-A" that closes successfully
-    And I have another mock async resource named "leaky-res-B"
-    When I register both resources with names "closed-res-A" and "leaky-res-B"
-    And I close all tracked resources with timeout 0.1 (only res-B times out)
-    Then timed_out_resources should contain "leaky-res-B"
-
-
-  # ========================== LEVEL 7 — ASYNC CONTEXT MANAGER PROTOCOL ==========================
-
-  @context-manager
-  Scenario: Context manager — __aenter__ returns self
-    When I enter the tracker as an async context manager
-    Then the returned object should be the same tracker instance
-
-  @context-manager
-  Scenario: Context manager — __aexit__ calls close_all on exit (no exception)
-    Given I have a mock async resource named "ctx-res-enter"
-    When I use the tracker as an async context manager and register the resource
-    And I exit the context manager successfully
-    Then the resource "ctx-res-enter" should be closed
-
-  @context-manager
-  Scenario: Context manager — __aexit__ propagates exception (returns False)
-    Given I have a mock async resource named "ctx-exception-tracked"
-    When I use the tracker as an async context manager with an outgoing exception
-    Then the tracker still calls close_all even when an exception occurs
-
-  @context-manager
-  Scenario: Context manager — __aexit__ sets no suppression (returns False)
-    Given I have a mock async resource named "no-suppress-res"
-    When I exit the context manager and check the result
-    Then __aexit__ should return False (exception is not suppressed)
-
-
-  # ========================== LEVEL 8 — OPEN COUNT QUERY ==========================
-
-  @query
-  Scenario: open_count — reports zero before any registration
-    Given I have an empty async resource tracker
-    Then the tracker open_count should be zero
-
-  @query
-  Scenario: open_count — incremented by one per successful registration
-    Given I have 3 new mock async resources named "count-1", "count-2", and "count-3"
-    When I register all three resources
-    Then the tracker open_count should be 3
-
-  @query
-  Scenario: open_count — decremented after close_all even if some resources failed/cancelled
-    Given I have 2 mock async resources:
-      | name       | close_delay_seconds |
-      | q-fast     | 0.0                 |
-      | q-slow     | 5.0                 |
-    When I register both resources
-    And I close all with timeout 0.1
-    Then the tracker open_count should be zero
-
-
-  # ========================== LEVEL 9 — EDGE CASES AND ERROR HANDLING ==========================
-
-  @edge-case
-  Scenario: Edge case — register with numeric-looking name string (e.g. "123")
-    When I register a mock async resource with name "123"
-    Then no exception should be raised and open_count should be 1
-
-  @edge-case
-  Scenario: Edge case — very long resource names are accepted
-    When I register a mock async resource with a very long name of 500 characters
-    Then no exception should be raised and open_count should be 1
-
-  @edge-case
-  Scenario: Edge case — close_all with unusually large timeout (1e9) still works
-    Given I have a mock async resource named "long-timeout-res"
-    When I register the resource with name "long-timeout-res"
-    And I close all tracked resources with a 999999.0 second timeout
-    Then the resource should be closed normally
