[DiamondDagger590]

Summary

• Add PlayerStatisticDataSetCoverageTest covering the unlimited-set branch (maxSetSize=-1) in addToSet(), including no-eviction behavior, duplicate detection, and large-set preservation
• Add getModifiedEntries edge case tests for unregistered statistics (value present but statistic removed from registry) and mixed registration status
• Add connection-close verification tests to both CreateCoreTablesFunctionTest and UpdateCoreTablesFunctionTest ensuring try-with-resources properly closes connections
• Add table-creation code path test to CreateCoreTablesFunctionTest exercising the tableExists=false branch

Coverage Impact

• PlayerStatisticData branch coverage: 96.2% → 97.4% (closed the maxSize <= 0 branch in addToSet)
• Overall project branch coverage: 70.7% → 70.8%
• All 2131+ tests pass

Classes Targeted

Class	What was covered
PlayerStatisticData	addToSet() unlimited set path, getModifiedEntries() unregistered-statistic edge cases
CreateCoreTablesFunction	Connection close via try-with-resources, table creation when tables don't exist
UpdateCoreTablesFunction	Connection close via try-with-resources

Test Plan

• All existing tests pass (./gradlew test — BUILD SUCCESSFUL)
• JaCoCo coverage report confirms branch improvement
• Testing audit persona (review-testing) run — no blocking concerns found
• New tests follow methodUnderTest_expectedOutcome_whenCondition naming convention
• All new test methods carry @DisplayName annotations

📝 Walkthrough

Walkthrough

The pull request adds tests for database connection cleanup and table creation. It also adds coverage for unlimited sets, duplicate values, large collections, and modified entries in PlayerStatisticData.

Changes

Test coverage

Layer / File(s)	Summary
Database table-function coverage src/test/java/com/diamonddagger590/mccore/database/table/function/CreateCoreTablesFunctionTest.java, src/test/java/com/diamonddagger590/mccore/database/table/function/UpdateCoreTablesFunctionTest.java	Tests verify connection closure after table creation and updates. They also verify successful table creation when tables do not exist.
PlayerStatisticData edge-case coverage src/test/java/com/diamonddagger590/mccore/statistic/PlayerStatisticDataSetCoverageTest.java	Tests verify unlimited set behavior, duplicate handling, preservation of many elements, and filtering of modified entries by registered statistics.

The added test can pass even if absent tables are never created. Add an execution assertion to make the intended regression coverage effective.

No blocking issues found

This PR only adds/modifies test files (CreateCoreTablesFunctionTest, UpdateCoreTablesFunctionTest, PlayerStatisticDataSetCoverageTest) — no src/main code changed. Ran the review-testing lens (test quality, naming conventions, extension usage, edge-case coverage) and review-extensibility lens (routed due to the database/ path match); both returned clean.

Verified specifically:

• New tests correctly exercise previously-uncovered branches: addToSet's unlimited (maxSetSize = -1) path, getModifiedEntries's unregistered/mixed-registration edge cases, and the tableExists = false table-creation path.

• RegistryResetExtension usage in @BeforeEach/@AfterEach matches the established convention (direct static calls, not @ExtendWith).

• Connection-close assertions correctly validate the try-with-resources behavior in the production lambdas.

• Naming (methodUnderTest_expectedOutcome_whenCondition) and @DisplayName conventions are followed throughout, and the reused executor field (not newly introduced) avoids any ManagedExecutorExtension concern.

• Gather context (PR diff, changed files)

• Route to review lenses — test-only PR (no src/main changes); ran review-testing and review-extensibility

• Run lens subagents

• Consolidate findings

• Post final review

123-124: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Assert that table creation is attempted.

When tableExists returns false, the test only checks future completion. It does not detect skipped PreparedStatement execution.

Suggested assertion

        assertTrue(result.isDone());
        assertFalse(result.isCompletedExceptionally());
+        org.mockito.Mockito.verify(mockStatement, org.mockito.Mockito.atLeastOnce()).executeUpdate();
