Summary

  • Adds ~55 new tests across CustomBlockWrapperTest, CustomItemWrapperTest, and CustomEntityWrapperTest targeting previously-untested hook-interaction and vanilla-fallback code paths
  • Prior coverage for the util/item package was ~35.7% line / ~50% branch — these tests cover the Constructor(Block/ItemStack/Entity), blockName/itemName/entityName vanilla branches, equals(Block/Entity), itemBuilder, customModels, drops, removeBlock, and playBlockDropEffects methods
  • Introduces reusable test helper classes (ConfigurableBlockHook, ConfigurableItemHook, ConfigurableEntityHook, TrackingBlockHook, ConfigurableItemHookForBlock) for flexible hook behavior simulation

What's covered

Method / Path Block Item Entity
Constructor from Bukkit type (5 branch variants)
*Name() vanilla branch (translationKey → lang tag)
*Name() hook-doesn't-recognize fallback
equals(Block/Entity) (5 variants) N/A
itemBuilder() (3 variants) N/A
customModels() static (3 variants)
drops() hook + vanilla fallback N/A N/A
removeBlock() hook + vanilla fallback N/A N/A
playBlockDropEffects() hook + vanilla fallback N/A N/A

Test plan

  • All new tests pass locally (./gradlew test)
  • Full test suite passes with no regressions
  • Testing audit persona (review-testing) run — both flagged gaps (missing drops and playBlockDropEffects vanilla fallback tests) were addressed
  • MockBukkit lifecycle properly managed (try-finally or @BeforeEach/@AfterEach)
  • RegistryResetExtension used for singleton state isolation

Summary by CodeRabbit

  • Tests
    • Expanded automated coverage for custom blocks, entities, and items.
    • Added validation for naming, construction, comparisons, custom models, item builders, drops, removal, and visual/audio effects.
    • Added test scenarios for vanilla, recognized custom, and unrecognized content.
    • Introduced configurable test doubles to verify integration behavior across supported hooks.

Cover previously-untested methods across CustomBlockWrapper,
CustomItemWrapper, and CustomEntityWrapper:

- Constructor(Block/ItemStack/Entity): 5 tests each covering no-hooks,
  hook-with-models, hook-with-empty-models, hook-not-recognizing, and
  hook-returning-empty-optional paths.
- blockName/itemName/entityName vanilla branch: MockBukkit-wrapped tests
  verifying the <lang:key> tag output from translationKey().
- blockName/itemName/entityName hook-doesn't-recognize fallback.
- equals(Block/Entity): 5 tests each covering material match/mismatch,
  hook confirms/denies, and no-hooks-registered paths.
- itemBuilder: 3 tests each for vanilla, custom-no-hooks, and
  custom-with-hook paths (MockBukkit + CorePlugin mock lifecycle).
- customModels (static): 3 tests each for no-hooks, hook-with-models,
  and hook-with-empty-optional paths.
- drops: hook-provides-drops and vanilla-fallback (block.getDrops) paths.
- removeBlock: hook-delegates and no-hooks-sets-AIR paths.
- playBlockDropEffects: hook-delegates and vanilla-fallback (sound +
  particle) paths.

Expanded test coverage for custom block, entity, and item wrappers. Added MockBukkit, Mockito, Adventure, and configurable hook test doubles for fallback and integration behavior.

Changes

Wrapper Test Coverage

Layer / File(s) Summary
Custom block wrapper behavior
src/test/java/com/diamonddagger590/mccore/util/item/CustomBlockWrapperTest.java
Tests cover names, construction, equality, item builders, models, drops, removal, and block-drop effects. Configurable and tracking hooks provide integration test behavior.
Custom entity wrapper behavior
src/test/java/com/diamonddagger590/mccore/util/item/CustomEntityWrapperTest.java
Tests cover names, construction, equality, and custom-model lookup. A configurable hook supplies entity detection and model results.
Custom item wrapper behavior
src/test/java/com/diamonddagger590/mccore/util/item/CustomItemWrapperTest.java
Tests cover item names, ItemStack construction, item builders, and custom-model lookup. A configurable hook supplies item recognition and results.

Merge Risk: 🔵 Low · up to 8885f

The PR adds test coverage without changing production behavior, but the new generic tests hard-code external-plugin identifiers, which couples them to specific integrations and reduces test portability. This is a bounded, non-blocking cleanup that should be addressed with owner awareness or follow-up.

Remove external-plugin identifiers from generic wrapper tests.

These tests hard-code nexo: and mythicmobs: identifiers. Use neutral fixture namespaces such as test: in the test hooks, test inputs, and assertions.

  • src/test/java/com/diamonddagger590/mccore/util/item/CustomBlockWrapperTest.java#L450-L454: Replace the nexo: fixture identifier and matching helper values.
  • src/test/java/com/diamonddagger590/mccore/util/item/CustomEntityWrapperTest.java#L413-L417: Replace the mythicmobs: fixture identifier and matching helper values.
  • src/test/java/com/diamonddagger590/mccore/util/item/CustomItemWrapperTest.java#L385-L389: Replace the nexo: fixture identifier and matching helper values.

As per path instructions, “Any class, method, or field that references a specific consumer plugin by name” must be flagged.
