7-17: LGTM! Well-designed fixture for cache isolation.The fixture correctly sets up an isolated in-memory cache for testing and ensures proper cleanup before and after each test execution. This approach provides excellent test isolation.

26-39: Excellent test coverage for basic cache clearing functionality.This test effectively verifies that the clear_cache command properly removes various data types from the cache, including strings and dictionaries. The test structure with setup, execution, and verification is well-implemented.

26-26: Static analysis false positive: fixture arguments are correctly used.The static analysis tool incorrectly flags
setup_cacheas unused. This is a pytest fixture that executes setup/teardown logic automatically when declared as a function parameter. The fixture is working correctly to provide cache isolation between tests.The Ruff warnings about unused
setup_cachearguments are false positives. Pytest fixtures work by dependency injection through function parameters, and the fixture logic executes automatically without explicit calls in the function body.Also applies to: 48-48, 63-63

18-23: LGTM! Well-designed test fixture.The fixture properly handles cache setup and teardown, ensuring test isolation. The use of
@override_settingsat the fixture level is the correct approach.
26-33: LGTM! Clean helper functions.These helper functions provide good abstractions for cache state assertions, making the tests more readable and maintainable.
37-37: Note: "Unused argument" warnings are false positives.The static analysis tool flags
setup_cacheas unused arguments, but this is expected behavior for pytest fixtures. The fixture is used via dependency injection to ensure proper test setup and teardown.Also applies to: 55-55, 65-65

33-65:✅ Verification successful
Verify the clear_cache command exists and functions correctly.
The tests assume the
clear_cachemanagement command exists and works as expected. Let's verify the command is properly implemented.
🏁 Script executed:
#!/bin/bash # Description: Verify the clear_cache management command exists and is properly implemented # Expected: Find the command implementation and ensure it properly clears the cache # Search for the clear_cache management command implementation fd "clear_cache.py" --type f | head -5 # Check if the command is in the expected location ls -la backend/apps/common/management/commands/clear_cache.py 2>/dev/null || echo "Command file not found at expected location" # Search for the command implementation pattern rg -A 10 "class.*Command.*BaseCommand" backend/apps/common/management/commands/clear_cache.py 2>/dev/null || echo "Command class not found"Length of output: 536
Clear_cache command implementation verified
The
clear_cachemanagement command is present atbackend/apps/common/management/commands/clear_cache.pyand itshandle()method correctly callscache.clear(), satisfying the existing tests. No further changes are needed.🧰 Tools

LocMemCachewith a specific location is appropriate for the test environment. This ensures isolated, in-memory cache operations that won't interfere with other environments or tests.backend/tests/apps/common/management/commands/clear_cache_test.py (4)

13-19: Well-designed helper methods.The assertion helper methods effectively reduce code duplication and provide clear, reusable functionality for verifying cache state. The naming is descriptive and the implementation is straightforward.
21-35: Comprehensive test for populated cache clearing.This test effectively verifies that the clear_cache command properly removes various data types from the cache. The test data includes different value types (strings and nested dictionaries) which provides good coverage.
