Summary

  • New test class MethodsMockBukkitTest: Covers all 7 previously-untested registry lookup methods in Methods.java (getItemType, getEnchantment, getTrimPattern, getTrimMaterial, getPatternType, getEntityType, getPotionEffect) with empty-string, valid-key, unknown-key, and case-insensitivity tests. Also covers fromBase64 with a round-trip serialize/deserialize assertion.
  • Extended CorePlayerTest: Added multi-hook isAfk() tests exercising the iteration path where the first AfkPluginHook returns false and a subsequent one returns true, plus the all-false multiple-hooks path. Uses distinct inner classes (NotAfkPluginHook, AlwaysAfkPluginHook) to satisfy PluginHookRegistry's class-keyed storage.

Coverage Impact

Class Metric Before After
Methods.java Branch ~81% 100%
Methods.java Line ~96% 99.4%
Overall Line 80.6% 80.7%

Test Plan

  • All new tests pass (./gradlew test)
  • Full test suite passes with no regressions
  • Reviewed by review-testing audit persona — findings addressed (strengthened fromBase64 assertion, added case-insensitivity tests)
  • MockBukkit setup/teardown is correct (mock in @BeforeEach, unmock in @AfterEach)
  • RegistryResetExtension used in CorePlayerTest to prevent singleton leaks

Summary by CodeRabbit

  • Tests
    • Added coverage for AFK status checks across multiple plugin hooks.
    • Added validation for registry lookups, including item types, enchantments, materials, entity types, banner patterns, trim patterns, and potion effects.
    • Verified handling of empty and unknown values, case-insensitive item lookups, and Base64 item-stack deserialization.

…rePlayer multi-hook isAfk

Add MethodsMockBukkitTest covering all 7 registry lookup methods
(getItemType, getEnchantment, getTrimPattern, getTrimMaterial,
getPatternType, getEntityType, getPotionEffect) with empty-string,
valid-key, unknown-key, and case-insensitivity tests. Also covers
fromBase64 with a round-trip serialize/deserialize assertion.

Add multi-hook isAfk tests to CorePlayerTest exercising the iteration
path where the first AfkPluginHook returns false and a subsequent one
returns true, plus the all-false multiple hooks path.

Methods.java branch coverage: 100% (was ~81%)
Methods.java line coverage: 99.4% (was ~96%)

📝 Walkthrough

Walkthrough

Changes

CorePlayer AFK behavior

Layer / File(s) Summary
AFK hook aggregation tests
src/test/java/com/diamonddagger590/mccore/player/CorePlayerTest.java
Adds fixed-response AFK hooks and verifies CorePlayer.isAfk() across multiple registered hooks.

Methods MockBukkit coverage

Layer / File(s) Summary
Methods lookup and deserialization tests
src/test/java/com/diamonddagger590/mccore/util/MethodsMockBukkitTest.java
Adds MockBukkit tests for registry lookups, case-insensitive item types, empty and unknown keys, and Base64 item-stack deserialization.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 1b256

The change only adds test coverage and does not alter production behavior. It is mergeable with owner follow-up to isolate registry state between tests and add the required non-null annotations, addressing bounded test reliability and contract-hygiene risks.

Reset registry singleton state after each test.

This class calls MockBukkit.unmock(), but it does not use RegistryResetExtension or InternalResetTestTools. Add one required reset mechanism so registry state cannot leak between test methods.

As per coding guidelines, “Use RegistryResetExtension or InternalResetTestTools to reset singleton state between tests.” Based on learnings, “Set up and tear down MockBukkit correctly (MockBukkit.mock() / MockBukkit.unmock()) without leaking across tests.”

Add @NotNull to all three hook parameters.

AfkPluginHook.isAfk requires a non-null CorePlayer. Annotate the parameters in all three test overrides and import org.jetbrains.annotations.NotNull.
