AdvancedCrafting previously ran four tests without coverage measurement. This introduces a 113-test regression/scenario suite across the complete production code and enforces 100% instruction, branch, and line coverage in normal builds and release CI, with downloadable JaCoCo reports.

The tests exposed fixes for permission loss, fresh-install startup, malformed configuration/index input, invalid preview icons and menu capacity, crafting/forge state handling, MMOItems tier metadata restoration, stale recipe retry recursion, and station data loss. The fixes are listed below; no deployment or release is included.

Validation

  • Java 21: mvn -o -B --no-transfer-progress clean verify -DskipTests=false -Dmaven.test.skip=false passed.
  • 113 tests passed; zero failed, errored, or skipped.
  • 90 instrumented production classes; 4,390/4,390 lines, 2,353/2,353 branches, 19,638/19,638 instructions.
  • No production coverage exclusions.
  • Runtime JAR filename/embedded-version validation passed; workflow YAML parsed; git diff --check passed.
  • MockBukkit supplies server state; mocks isolate pinned external plugin boundaries. This is Java behavior coverage, not a live-server deployment test.

Regression cases

  • Configured category permissions survive parsing.
  • Fresh installs create the model-scheme directory used by config loading.
  • Invalid stat-offset syntax and short legacy recipe filenames do not abort loading.
  • Preview menus cap entries at inventory size and replace AIR icons with a barrier.
  • Station persistence uses the plugin data directory and actual world name; an
    absent station directory loads as an empty database. Rejected files, including
    stations whose worlds are not loaded, survive shutdown cleanup and become
    prunable only after a successful reload. New saves choose another UUID when
    their candidate filename belongs to a retained rejected station.
  • Bukkit command metadata uses the valid usage key, allowing a real plugin boot.
  • MMOItems rebuilds restore the tier line from old metadata when the builder omits it.
  • Alloy renaming cannot overwrite a different alloy's existing ID.
  • Cancelled forge interactions, offhand interactions and cancelled block breaks
    preserve station contents. Removed ingredient/alloy definitions cannot crash
    material admission or consume the held item.
  • Nonfinite admin quality values cannot arm an invalid craft.
  • Failed stale recipe deletion reaches the forge retry limit instead of recursing
    forever.
  • Renewing an admin craft request survives the previous request's timeout.
  • Unknown persisted material kinds cannot provide a craft's main material and do
    not prevent refunds of the known materials.

Equivalent simplifications

These changes remove redundant work, with surrounding behavior exercised by the
suite. They do not replace guards with fabricated test states.

Code Invariant and preserved behavior
CraftingManager.openStation A station without a recipe already opens the category menu and returns. A second branding-tool check for that same condition cannot run successfully.
Crafting/conversion hand checks Bukkit's PlayerInventory.getItemInMainHand() returns a nonnull stack. The AIR checks remain; nullable inventory-click stacks retain their null checks.
IngredientManager.convertItem An untagged item's nonnull resolved stats require a successful getFromItem lookup; no mutation occurs before the repeated lookup. Unknown inputs still return at the stats guard.
AcItemTags.getId A nonnull kind already requires item metadata and a string ID in its persistent data container.
AcItemLoreRefresher A known kind already implies a stored string ID. Unknown items still return unchanged.
CraftInspectFormatter isCrafted() requires the recipe string used by CraftProvenance.readFrom; absent optional provenance fields receive defaults.
IngredientData.hasPermission Its private permission field is assigned only a trimmed, nonblank string, or remains null.
StatTemplate icon validation The configuration lookup supplies v.paper as its nonnull default. A regression test with Bukkit’s actual YAML parser verifies explicit null, ~, an empty value, and an omitted icon all use that default, while a later template still loads with its configured icon. Invalid non-path strings still produce the warning.
AlloyRecipeStore Index paths always include a parent directory. readIndexEntry returns null before constructing an entry with a null result ID.
MajorityTierResolver The initial guard rejects empty maps, so fallback can return the first key directly.
Crafting hit percentage Percentages at or above 200 already continue; the second <= 200 test was dominated. NaN retains the existing comparisons and outcome.
Armor refresh An exhaustive switch expression chooses the same four inventory setters and eliminates the enum statement's unreachable default arm.

📝 Walkthrough

Walkthrough

The pull request adds JaCoCo coverage enforcement and CI report uploads, introduces a broad MockBukkit test suite, and changes crafting, alloy, item, configuration, and persistence behavior.

Changes

Coverage and runtime behavior

Layer / File(s) Summary
Test and coverage setup
.github/workflows/*, pom.xml, README.md, src/test/.../CoverageSupport.java
The Maven build adds JUnit Jupiter, Mockito, MockBukkit, Surefire, and JaCoCo. verify enforces 100% instruction, line, and branch coverage. CI uploads JaCoCo reports. The README documents the test workflow, and shared test support initializes and restores mocked plugin state.
Configuration and domain behavior
src/main/.../AdvancedCrafting.java, src/main/.../loaders/ConfigLoader.java, src/main/.../objects/data/*, src/main/.../objects/stats/StatTemplate.java, src/main/.../objects/crafting/RecipeCategory.java, src/main/.../utils/MajorityTierResolver.java, src/main/resources/plugin.yml, src/test/.../{BridgeCoverageTest,DomainCoverageTest,LoaderCoverageTest,MathCoverageTest,CompatibilityCoverageTest,LifecycleCoverageTest,PluginLifecycleCoverageTest}.java
Runtime changes update directory creation, malformed offset parsing, permission handling, category configuration, majority-key fallback, and command metadata. Added tests cover loaders, domain values, math, bridge behavior, compatibility, lifecycle events, and plugin setup.
Alloy and station persistence
src/main/.../database/*, src/test/.../{AlloyDatabaseCoverageTest,PersistenceCoverageTest,StationDatabaseCoverageTest,EdgeCoverageTest}.java
Alloy recipe parsing and station persistence change their path resolution, handling of missing or malformed data, and file tracking. Tests cover recipe and station persistence, legacy inputs, unreadable files, and filesystem edge cases.
Crafting and alloy workflows
src/main/.../managers/{AlloyManager,CommandManager,CraftingManager,IngredientManager}.java, src/main/.../objects/{alloys/AlloyForger.java,crafting/CraftingStation.java}, src/test/.../{AlloyDomainCoverageTest,AlloyManagerCoverageTest,CommandCoverageTest,CraftingManagerCoverageTest,ForgerCoverageTest,IngredientManagerCoverageTest,StationCoverageTest}.java
Runtime changes affect event filtering, alloy naming, command quality validation, pending-craft timeouts, forging random draws and retries, station material checks, quality calculations, and unknown-material handling. Tests exercise these paths and related outcomes.
Item refresh and menus
src/main/.../managers/{CraftRefreshListener,InventoryManager,MMOItemRebuildListener}.java, src/main/.../utils/{AcItemLoreRefresher,AcItemTags,CraftInspectFormatter}.java, src/test/.../{EdgeCoverageTest,FormatterCoverageTest,ItemMetadataCoverageTest,MenuCoverageTest,MmoCoverageTest,RefreshListenerCoverageTest}.java
Item refresh and rebuild handling change metadata checks and tier-data application. Menu previews now stop at inventory capacity and use barrier icons for null or air templates. Tests cover item tags, lore, tier metadata, menus, MMO stat handling, and formatter behavior.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~60 minutes

Change: Bug fix

Merge Risk: ⚪ Minimal · up to affea

No concrete merge-blocking regression remains established. Null template icons use the paper default, and the investigated conversion and inspection paths remain guarded. Merge after normal build checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to affea

Permission preservation and cancellation handling improve. A conditional forge-recovery gap remains: if a stale recipe index cannot be deleted, retry exhaustion can consume station inputs without producing an item. Live-server recovery behavior is not fully established.

Retained concerns

  • Low · reliability · inferred: If a stale recipe index remains readable because deletion fails, the new bounded retry eventually returns null without producing an output. AlloyManager interprets that return as a completed forge, replaces the held item with a bucket, and removes the station without refunding its inputs. The previous unchanged retry counter did not reach this terminal cleanup path. This is a conditional recovery-contract gap affecting item ownership; successful index deletion avoids it.
Security review details

Security Blast Radius

  • inferred — The identified forge failure affects station inputs and the invoking player's held item within the plugin's server-side item economy. It requires a stale alloy result and failed index deletion; direct player control over that filesystem condition was not established.

Trust Boundaries and Controls

  • observed — Cancelled block-break events now return before station refund or removal. Alloy ingredient interactions also reject cancelled and off-hand events. Ingredient permission checks precede the inspected crafting material mutations and forge execution.

Resilience and Maintainability Implications

  • observed — Unknown persisted material kinds are rejected as craft outputs and skipped during refunds, allowing reconstructable entries to continue through cleanup rather than aborting the entire refund. The unknown entry itself remains unrecoverable.

Hardening Proposals

  • proposed — Represent forge success, scrap output, and failure as distinct outcomes. On retry exhaustion, preserve or refund station inputs rather than performing successful-forge cleanup.

I’m a rabbit with tests in my burrow tonight,
Coverage reports glow in the soft moonlight.
I hop through the recipes, the stations, the code,
Then nibble a carrot beside the build road.
The checks finish their run, and my ears stand tall.
