[Tests] Expand item builder test coverage (BaseItemBuilder, ItemBuilder section, SpawnerBuilder)

[DiamondDagger590]

Summary

• BaseItemBuilderTest: Added 20 new tests covering previously untested methods:

  • withType — early-return path when itemStack already exists
  • setColor — map (MAP_COLOR), leather armor (DYED_COLOR), potion (DYED_COLOR), shield (BASE_COLOR), non-colorable item (no-op), and RGB string input
  • getPlainName — ITEM_NAME present, CUSTOM_NAME fallback, no data, null data
  • getPlainLore — LORE data present, no data, null data
  • addEnchantment(Enchantment, int) — regular item (no existing/existing enchantments), enchanted book (no stored/existing stored enchantments), null data handling, and enchanted book fallthrough to ENCHANTMENTS branch when STORED_ENCHANTMENTS absent

• ItemBuilderSectionTest: Added 10 new tests for ItemBuilder.from(Section) config parsing paths:

  • Potion effects (valid and unknown potion names)
  • Banner patterns
  • Display name and lore from section
  • Spawner mob type (valid and empty)
  • Multiple enchantments
  • Item flags
  • Custom model data

• SpawnerBuilderTest: Added 6 new tests using a mocked CreatureSpawnerMeta bridge interface:

  • All positive values set all spawner properties
  • Zero values skip count/delay/range setters
  • Selective positive values (only count set)
  • Default delay of 3 applied when not explicitly set, with count/range verified as not called
  • Negative values treated as unset (same as zero)

Test plan

• All new tests pass (./gradlew test --tests "...BaseItemBuilderTest" --tests "...SpawnerBuilderTest" --tests "...ItemBuilderSectionTest" --tests "...ItemBuilderTest")
• No regressions introduced (pre-existing failures in FireworkBuilderTest, FireworkStarBuilderTest, CorePlayerMockBukkitTest are unrelated)
• Ran testing audit persona — addressed valid findings (missing enchanted book branch, SpawnerBuilder negative values, default delay assertions)

📝 Walkthrough

Walkthrough

Added test coverage for base item builder operations, section-based item configuration, and spawner metadata handling. The changes add no production code or public API declarations.

Changes

Item Builder Test Coverage

Layer / File(s)	Summary
Base item builder behavior src/test/java/com/diamonddagger590/mccore/builder/item/BaseItemBuilderTest.java	Tests cover item types, color data, plain names, plain lore, and enchantments.
Section item configuration src/test/java/com/diamonddagger590/mccore/builder/item/impl/ItemBuilderSectionTest.java	Tests cover potion effects, banner patterns, display data, spawner types, enchantments, item flags, and custom model data.
Spawner metadata behavior src/test/java/com/diamonddagger590/mccore/builder/item/impl/SpawnerBuilderTest.java	Mockito tests cover positive, zero, negative, and default spawner metadata values.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: ⚪ Minimal · up to 8271f

This change expands automated coverage without altering production behavior. A few tests could assert configured metadata and preserved values more precisely, but no actionable merge-blocking risk remains.

265-267: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Assert the configured metadata values.

These tests pass if ItemBuilder.from(section) ignores the configured values. They only assert that construction does not throw or returns a non-null builder.

• src/test/java/com/diamonddagger590/mccore/builder/item/impl/ItemBuilderSectionTest.java#L265-L267: Assert the potion effect type, duration, and amplifier.

• src/test/java/com/diamonddagger590/mccore/builder/item/impl/ItemBuilderSectionTest.java#L305-L307: Assert the display name.

• src/test/java/com/diamonddagger590/mccore/builder/item/impl/ItemBuilderSectionTest.java#L362-L364: Assert ItemFlag.HIDE_ENCHANTS.
• src/test/java/com/diamonddagger590/mccore/builder/item/impl/ItemBuilderSectionTest.java#L372-L374: Assert custom model data is 42.

1515-1525: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Assert preservation of existing enchantments.

The existing-enchantment fixtures return Map.of(), so the tests do not exercise preservation. Add an existing enchantment, capture the written ItemEnchantments, and assert that it contains both enchantments at the expected levels.

Use ItemType.STONE instead of null in this test.

withType requires a non-null ItemType. The existing ItemStack prevents the method from using the argument, so null does not test valid behavior.

Assert the color payload, not only its type.

The setColor tests use any(...), so they pass when the implementation writes the wrong value. Capture each payload and assert the expected Color or DyeColor, including the RGB case.

Add an ITEM_NAME precedence test.

When both components are present, assert that getPlainName() returns the ITEM_NAME value.
