Summary

  • CorePlayer: Add tests for setPlayerSetting() (stores setting, fires PlayerSettingChangeEvent with correct old/new setting and player reference), getAsBukkitPlayer() (online returns Player, offline returns empty), and getPlayerSettings() after adding multiple settings. Bukkit-dependent tests use a shared @Nested class with proper @BeforeEach/@AfterEach server lifecycle.
  • BaseGui: Add two missing branch tests for handleClickEvent — bottom inventory click when allowBottomInventoryClick() returns true (verifies no cancellation and no slot delegation via getClick() never called), and top inventory click when CorePlayer not found by PlayerManager (verifies no setCancelled).
  • GuiManager: Replace the weak verify(callEvent(any())) test with three precise KeyedGui integration tests — verifies CoreGuiOpenEvent carries correct NamespacedKey for a KeyedGui, empty key for KeyedGui returning empty, and null key for non-KeyedGui.

Coverage Improvements

Class Branch (before → after) Line (before → after)
GuiManager 92.9% → 100% 97% → 100%
BaseGui 90.9% → 95.5% ~95% → 98%
CorePlayer setPlayerSetting + getAsBukkitPlayer now covered 96.7% maintained

Test Plan

  • All existing tests pass (./gradlew test — BUILD SUCCESSFUL)
  • New CorePlayer tests verify event payload (old setting, new setting, player reference)
  • New BaseGui tests cover both missed branches in handleClickEvent
  • New GuiManager tests verify CoreGuiOpenEvent key for keyed, empty-keyed, and non-keyed GUIs
  • Testing audit persona (review-testing) run against changes; all findings addressed

Summary by CodeRabbit

  • Tests
    • Expanded coverage for configurable bottom-inventory click handling.
    • Added validation for GUI open events, including player, GUI, and optional key details.
    • Added coverage for player settings, including storage, replacement events, retrieval, and online/offline player access.

Add tests for previously uncovered methods and branches:

- CorePlayer: setPlayerSetting (stores setting, fires
  PlayerSettingChangeEvent with correct old/new setting and player
  reference), getAsBukkitPlayer (online and offline), getPlayerSettings
  after adding multiple settings
- BaseGui: handleClickEvent when allowBottomInventoryClick() returns
  true (verifies no cancellation and no slot delegation), handleClickEvent
  when CorePlayer not found by PlayerManager (verifies no setCancelled)
- GuiManager: KeyedGui integration in trackPlayerGui — verifies
  CoreGuiOpenEvent carries correct NamespacedKey for KeyedGui, empty key
  for KeyedGui returning empty, and null key for non-KeyedGui

Coverage improvements:
- GuiManager: 92.9% → 100% branch, 97% → 100% line
- BaseGui: 90.9% → 95.5% branch, ~95% → 98% line
- CorePlayer: setPlayerSetting and getAsBukkitPlayer now fully covered

Review complete — 0 important, 2 nits

Scope: This PR only touches test files (BaseGuiTest, GuiManagerTest, CorePlayerTest) — no src/main changes. Per the routing table in .github/claude-review-prompt.md, review-testing is the only applicable lens (the other lenses gate on src/main/**/*.java changes). The new tests correctly exercise the two missing branches in BaseGui.handleClickEvent, the three CoreGuiOpenEvent key-payload paths in GuiManager, and add solid coverage for CorePlayer.setPlayerSetting() / getAsBukkitPlayer() via a @Nested class with proper Bukkit server setup/teardown.

Nits (2)
  • src/test/java/com/diamonddagger590/mccore/gui/GuiManagerTest.java:342,364 — @SuppressWarnings("unchecked") on trackPlayerGui_firesEventWithKey_whenGuiIsKeyed and trackPlayerGui_firesEventWithEmptyKey_whenKeyedGuiReturnsEmpty doesn't correspond to any real unchecked operation — mock(KeyedGuiImpl.class) is not a raw-type mock (unlike createMockGui()'s mock(Gui.class) at line 69, which genuinely warrants the suppression), and (KeyedGui) keyedGui is a plain interface downcast. Safe to drop the annotation from these two methods.
  • src/test/java/com/diamonddagger590/mccore/gui/BaseGuiTest.java:526,556 — same dead-suppression pattern on the two new tests (handleClickEvent_doesNotCancel_whenBottomInventoryClickedAndAllowed, handleClickEvent_doesNotCallSetCancelled_whenCorePlayerNotFound); neither body performs an unchecked cast. Note this mirrors an existing pattern already present on the sibling test directly above (line 502), so it's consistent with current file style even if not strictly necessary.

No blocking issues. Nice use of ArgumentCaptor to assert actual event payloads instead of verify(callEvent(any())), and good branch coverage on the allowBottomInventoryClick() / "CorePlayer not found" paths.

Changes

GUI click handling

Layer / File(s) Summary
Base GUI click behavior
src/test/java/com/diamonddagger590/mccore/gui/BaseGuiTest.java
The tests configure bottom-inventory clicks and verify behavior for allowed clicks and missing CorePlayer instances.

GUI open event assertions

Layer / File(s) Summary
GUI open event payloads
src/test/java/com/diamonddagger590/mccore/gui/GuiManagerTest.java
The tests capture CoreGuiOpenEvent and verify the player UUID, GUI reference, and optional NamespacedKey.

CorePlayer Bukkit behavior

Layer / File(s) Summary
Bukkit test harness and setting behavior
src/test/java/com/diamonddagger590/mccore/player/CorePlayerTest.java
The tests mock Bukkit services and verify player settings, setting-change events, and online or offline player conversion.

Priority: ⬇️ Low

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

Change: Other

Merge Risk: 🔵 Low · up to d7dae

The new coverage should be strengthened before merge so Bukkit behavior and missing-player GUI handling remain reliably protected. The risk is limited to the added test suite.

556-580: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Assert that the missing-player branch is reached. BaseGui.handleClickEvent consults PlayerManager.getPlayer before it calls canProcessEvent, but a false result still skips the missing-player Optional.map branch. The current cancellation assertions therefore pass without testing that branch. Assert that gui.canProcessEvent(mockBukkitPlayer, mockInventory) is true before invoking the handler. Verifying that event.getClick() is never called is not needed because the precondition and empty player result already prove that Slot.onClick() is not reached.

240-240: 📐 Maintainability & Code Quality | 🔵 Trivial | 🏗️ Heavy lift

Use MockBukkit for Bukkit objects.

This fixture mocks Bukkit Server and Player objects and mutates Bukkit.server through reflection. MockBukkit 4.108.0 is configured, and CorePlayerMockBukkitTest demonstrates that MockBukkit.mock() with ServerMock.addPlayer() supplies the required behavior. Replace this fixture with MockBukkit.mock()/MockBukkit.unmock() and the provided server/player implementations.

Document the public helper methods.

TestGui.allowBottomInventoryClick() and TestGui.setBottomClickAllowed(boolean) lack Javadoc. The repository guidance applies to all Java methods, including test helpers. Add @return documentation to allowBottomInventoryClick() and @param documentation to setBottomClickAllowed(boolean).
