Summary

Adds unit tests for three previously uncovered classes, improving overall test coverage:

  • SkillExperienceContextTest — Tests the abstract base class and both concrete subclasses (BlockBreakContext, EntityDamageContext). Covers base experience clamping (Math.max(0, baseExperience)), accessor correctness, default gain reason (OTHER), and subclass gain reason overrides (BLOCK_BREAK, ENTITY_DAMAGE).

  • StateTypeWarningLogTest — Tests the warn-once deduplication logic used by the combat state system. Covers first-call logging, suppression of duplicate warnings for the same key, independent logging for distinct keys, throwable cause forwarding, and namespace-aware key distinction.

  • PendingRewardTest — Tests the quest reward DTO. Covers accessor correctness for all fields, defensive copy of the serialized config map (source mutation isolation), immutability of the returned map, and empty map handling.

Summary by CodeRabbit

  • Tests
    • Added coverage for one-time warning logging, including duplicate keys, separate namespaces, and logging causes.
    • Added tests for pending reward accessors and configuration handling, including immutability and empty configurations.
    • Added tests for experience contexts, covering gain reasons, event references, and handling of negative and boundary experience values.

…endingReward

Cover three previously untested classes:
- SkillExperienceContext: base experience clamping, accessor correctness,
  default gain reason, BlockBreakContext and EntityDamageContext overrides
- StateTypeWarningLog: warn-once deduplication, distinct key handling,
  throwable forwarding, namespace-aware key distinction
- PendingReward: accessor correctness, defensive copy of serialized config
  map, immutability of returned map, empty map handling

📝 Walkthrough

Walkthrough

Adds tests for warning deduplication, pending reward accessors and config handling, and skill experience context behavior. The changes cover three independent areas and do not alter production declarations.

Pending reward tests

Layer / File(s) Summary
Reward data and config behavior
src/test/java/us/eunoians/mcrpg/quest/reward/PendingRewardTest.java
Tests accessor values and config copying, immutability, empty-map handling, and separation from the input map.

Skill experience context tests

The new tests add unnecessary server setup, but no production behavior change is identified. Removing the unused test-base inheritance is a bounded fix before merge.

Use plain JUnit for StateTypeWarningLogTest.

This class only mocks Logger, constructs StateTypeWarningLog, and uses NamespacedKey. Remove McRPGBaseTest so each test instance does not initialize MockBukkit and load McRPG.

Use plain JUnit for these context tests.

The context constructors only store their arguments and clamp experience values. These tests use Mockito mocks and do not require MockBukkit or McRPGPlayer setup. McRPGBaseTest performs MockBukkit setup and loads a fresh plugin for every test instance, adding unnecessary test overhead. The project guideline requires plain JUnit for this case.
