2287-2468: Consider extracting common test patterns to improve maintainability.While the current tests are comprehensive and correct, they contain significant code duplication. Consider extracting common patterns into helper methods to improve maintainability and reduce repetition.
For example, you could create helper methods like:
private function populateAndVerifyCache($behavior): void { // Common cache population and verification logic Assert::invokeMethod($behavior, 'getDepthValue'); Assert::invokeMethod($behavior, 'getLeftValue'); Assert::invokeMethod($behavior, 'getRightValue'); $depthValueProperty = Assert::inaccessibleProperty($behavior, 'depthValue'); $leftValueProperty = Assert::inaccessibleProperty($behavior, 'leftValue'); $rightValueProperty = Assert::inaccessibleProperty($behavior, 'rightValue'); self::assertNotNull($depthValueProperty, 'Depth value cache should be populated.'); self::assertNotNull($leftValueProperty, 'Left value cache should be populated.'); self::assertNotNull($rightValueProperty, 'Right value cache should be populated.'); } private function verifyCacheInvalidation($behavior): void { // Common cache invalidation verification logic $depthValueProperty = Assert::inaccessibleProperty($behavior, 'depthValue'); $leftValueProperty = Assert::inaccessibleProperty($behavior, 'leftValue'); $rightValueProperty = Assert::inaccessibleProperty($behavior, 'rightValue'); self::assertNull($depthValueProperty, 'Depth value cache should be invalidated.'); self::assertNull($leftValueProperty, 'Left value cache should be invalidated.'); self::assertNull($rightValueProperty, 'Right value cache should be invalidated.'); }

20-20: LGTM - Appropriate development dependency addition.The addition of
php-forge/supportas a development dependency is well-placed and uses an appropriate version constraint for supporting the new test functionality.src/NestedSetsBehavior.php (4)
284-306: Excellent centralized cache invalidation implementation.The
invalidateCache()method effectively centralizes the logic for clearing cached attribute values and resetting internal state. The implementation correctly clears all relevant cached properties (depthValue,leftValue,rightValue,node,operation) and provides comprehensive documentation with usage examples.
196-196: Proper cache invalidation after deletion.Calling
invalidateCache()after deletion operations ensures cached values remain consistent with the modified tree structure.
236-236: Appropriate cache invalidation after insertion.The cache invalidation after insert operations maintains consistency when new nodes are added to the tree.
268-268: Comprehensive cache invalidation in update scenarios.The strategic placement of
invalidateCache()calls in different update operation branches ensures cached values are properly cleared regardless of the operation type (make root, null node, or node movement).Also applies to: 274-274, 281-281
tests/NestedSetsBehaviorTest.php (5)
8-8: LGTM: Appropriate testing utility import.The
PHPForge\Support\Assertimport is correctly added to access protected/private properties and methods during testing, which is a standard practice for thorough unit testing.
2287-2336: Comprehensive cache invalidation test for makeRoot operation.The test thoroughly validates that:
- Cache values are initially populated and match expected attributes
- Cache is properly invalidated (set to null) after
makeRoot()operation- New cache values are correctly retrieved after invalidation and reflect root node state
The test methodology using
Assertto access private properties is appropriate for validating internal cache state.
2338-2379: Well-structured test for appendTo cache invalidation.This test effectively verifies that cache invalidation occurs during node movement operations. The pattern of populating cache, performing the operation, and then verifying cache is cleared is consistent with the other cache invalidation tests.
2381-2421: Thorough validation of cache invalidation during deletion.The test properly verifies that
deleteWithChildren()operation invalidates cached values. The setup with grandchild relationships provides good coverage for deletion scenarios involving multiple nodes.
2423-2468: Excellent test for manual cache invalidation.This test validates the direct usage of the
invalidateCache()method and confirms that:
- Cache can be manually cleared
- All expected properties are set to null
- Subsequent value retrieval works correctly after manual invalidation
The test provides good coverage for the public API of the cache invalidation functionality.
…troducing helper methods.

8-8: LGTM! Appropriate imports for testing cache invalidation.The imports are correctly added to support the new test functionality -
Assertfor accessing private/protected members andBehaviorfor type hinting.Also applies to: 10-10
2287-2341: LGTM! Comprehensive test for cache invalidation after makeRoot operation.The test properly verifies that:
- Cache values are initially populated and match the node attributes
- Cache is invalidated after
makeRoot()operation- New cache values reflect the updated root node state
2343-2371: LGTM! Well-structured test for cache invalidation during node movement.The test effectively verifies that cache is populated after initial placement and properly invalidated when the node is moved to a different parent.
2373-2400: LGTM! Properly tests cache invalidation after delete operations.The test ensures that cached values are cleared when a node and its children are deleted, preventing stale cache data.
2402-2438: LGTM! Validates the manual cache invalidation API.The test properly verifies that:
- Manual
invalidateCache()clears all cached values- Values can be correctly retrieved after cache invalidation
2495-2531: LGTM! Properly tests cache invalidation for single tree tables.The test correctly verifies cache invalidation behavior for models without a tree attribute.
2568-2638: LGTM! Comprehensive integration test for cache invalidation.The test effectively validates the complete flow of cache invalidation when a child node is promoted to root, ensuring all cached values are properly updated.
2640-2688: LGTM! Well-structured helper methods with proper type hints.The helper methods effectively encapsulate cache verification logic and reduce code duplication across tests. The PHPStan type hints ensure type safety.
…ehavior with operation setter.
…ull and implement `setNode` method in `ExtendableNestedSetsBehavior`.

Pull Request Overview
Adds a centralized cache invalidation mechanism to NestedSetsBehavior and verifies its use across tree operations through new tests and a stub behavior tracker.
- Introduces
invalidateCache()in the behavior and wires it intoafterInsert,afterDelete, andafterUpdate. - Provides a test stub (
ExtendableNestedSetsBehavior) to detect when cache invalidation is called. - Adds extensive PHPUnit tests to confirm cache clearing after various node operations and manual invocations.
- Adds a new dependency for assertion helpers used in tests.
