Summary

  • Add TemplateConditionEvaluationTest — comprehensive evaluate() tests for all 6 built-in TemplateCondition types (ChanceCondition, RarityCondition, PermissionCondition, CompletionPrerequisiteCondition, VariableCondition, CompoundCondition), plus constructor validation, serializeConfig() round-trips, and ConditionContext factory method verification.
  • Add ConditionParserAdditionalTest — tests for parsePrerequisiteBlock, explicit type resolution via TemplateConditionRegistry, the less-than variable shorthand, and error cases (unregistered type key, unrecognized check key).

Motivation

The existing TemplateConditionParsingTest covers YAML shorthand parsing but not the runtime evaluation logic. These tests close that gap, covering pass-through behavior (null context fields), boundary conditions (chance 0.0/1.0, completions exactly at threshold), filter forwarding, and all ComparisonOperator serialization paths.

Test plan

  • All new tests pass individually (./gradlew test --tests "us.eunoians.mcrpg.quest.board.template.condition.*")
  • Full suite passes (./gradlew verifiedShadowJar — BUILD SUCCESSFUL)
  • Reviewed against persona-testing.mdc audit checklist — no concerns found

Summary by CodeRabbit

  • Tests
    • Expanded coverage for quest template condition parsing and evaluation.
    • Added validation for prerequisite blocks, condition types, variable checks, chance, rarity, permissions, and completion requirements.
    • Added coverage for compound conditions, boundary cases, null handling, serialization, and condition context creation.
    • Improved confidence in handling built-in and registered third-party conditions.

Cover the evaluate() logic for all 6 built-in TemplateCondition types
(ChanceCondition, RarityCondition, PermissionCondition,
CompletionPrerequisiteCondition, VariableCondition, CompoundCondition),
ConditionContext factory methods, ConditionParser.parsePrerequisiteBlock,
explicit type resolution via registry, less-than variable shorthand,
and error cases for unrecognized check keys and unregistered types.

Changes

Condition testing

Layer / File(s) Summary
Condition parser coverage
src/test/java/us/eunoians/mcrpg/quest/board/template/condition/ConditionParserAdditionalTest.java
Tests prerequisite parsing, explicit built-in and third-party condition types, variable shorthand, and invalid condition checks.
Condition evaluation coverage
src/test/java/us/eunoians/mcrpg/quest/board/template/condition/TemplateConditionEvaluationTest.java
Tests chance, rarity, permission, completion prerequisite, and variable conditions, including validation, evaluation, and serialization.
Compound conditions and context factories
src/test/java/us/eunoians/mcrpg/quest/board/template/condition/TemplateConditionEvaluationTest.java
Tests compound condition modes, immutable child access, serialized child type keys, and ConditionContext factory fields.

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

Merge Risk: 🔵 Low · up to c7c57

This change only adds unit-test coverage and does not alter runtime behavior or production configuration. Merge readiness is low-risk but not entirely clean: several test helpers lack required documentation, one parser test does not verify the exact returned condition, and serialization checks cast values before validating their types, which can weaken failure diagnostics or allow an incorrect result to pass. These are bounded test-quality follow-ups rather than production-impacting defects.

163-165: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Assert the resolved third-party condition.

assertNotNull(result) passes if the parser returns a different registered condition. Assert that result is custom because this fixture returns itself from fromConfig.

Proposed fix
+import static org.junit.jupiter.api.Assertions.assertSame;
...
-            assertNotNull(result);
+            assertSame(custom, result);

Assert serialized value types before casting.

The serializeConfig() assertions can throw ClassCastException before reporting a schema mismatch. Use assertInstanceOf(Double.class, ...) for the five numeric values and assertInstanceOf(Map.class, ...) for both nested values before comparing or reading them.

📐 Maintainability & Code Quality | 🟠 Major | ⚡ Quick win

Add Javadoc to the new private helpers.

  • src/test/java/us/eunoians/mcrpg/quest/board/template/condition/ConditionParserAdditionalTest.java#L33-L39: document the YAML input, parsed section result, and parse-failure behavior of sectionFrom.
  • src/test/java/us/eunoians/mcrpg/quest/board/template/condition/TemplateConditionEvaluationTest.java#L122-L134: document the test rarity registry returned by createRarityRegistry.

As per coding guidelines, “Add Javadoc to every public and private method, documenting @param and @return semantics.”
