# Test Infrastructure & 4-Tier E2E Test Plan: D2GS v1.13c Online Gameplay Loops & Server Authority
|
||||
# Diablo II v1.13c Parity Test Infrastructure (`TEST_INFRA.md`)
|
||||
|
||||
## 1. Test Philosophy & Ground Truth Invariants
|
||||
|
||||
The `tests/e2e-d2gs-online/` suite is an opaque-box, requirement-driven 4-tier E2E test suite verifying all 16 features (`F1`–`F16`) defined in `PROJECT.md` and `ORIGINAL_REQUEST.md` (`2026-10-01T13:08:09Z`).
|
||||
|
||||
### Core Verification Principles
|
||||
1. **Diablo II v1.13c Binary & Data-Table Ground Truth**:
|
||||
- Every C2S binary packet emitted by `encodeD2gsClientCommand` / `clientCommandToC2sPackets` is verified against `C2S_PACKET_SIZES[opcode]` (`src/netproto/d2gs/tables/s2c-sizes.ts`) and exact little-endian wire layout (`u8`, `u16LE`, `u32LE`).
|
||||
- Every online item tooltip (`onlineItemDataToUiInventoryItem` and `HudModel.syncFromWorld()`) is verified against canonical 1.13c item tables (`getEmbeddedDropTables()`, `Armor.txt`, `Weapons.txt`, `Misc.txt`, `MagicPrefix.txt`, `MagicSuffix.txt`, `RarePrefix.txt`, `RareSuffix.txt`, `SetItems.txt`, `UniqueItems.txt`, `Runes.txt`, `ItemStatCost.txt`) — never raw `Stat #N: V` fallbacks.
|
||||
- Every Town and Quest NPC across Acts 1–5 is verified against `TOWN_NPC_DESCRIPTORS` and `NPC_HCIDX_TO_DESCRIPTOR_ID` (`src/common/units/npc-table.ts`).
|
||||
2. **Strict Server Authority (Zero Optimistic Client Mutation)**:
|
||||
- When `HudManager` / `WorldPanelsHud` has a `HudCommandSink` (`HudModel`) attached (`hasCommandSink === true`), UI interactions emit typed `ClientCommand` payloads and C2S wire bytes **without** mutating local inventory, equipment, belt, stash, cube, mercenary, party, or trade state ahead of the server.
|
||||
- Only authoritative `ServerEvent` updates applied to `ClientWorld` (`src/client/world/client-world.ts`) and synchronized via `HudModel.syncFromWorld()` (`src/client/ui-model/hud-model.ts`) mutate the visible UI state.
|
||||
3. **Opaque-Box Contract Testing**:
|
||||
- All tests interact through public module boundaries (`src/netproto/index.ts`, `src/common/items/item-bridge.ts`, `src/common/items/ground-items.ts`, `src/common/units/npc-table.ts`, `src/client/world/client-world.ts`, `src/client/ui-model/hud-model.ts`, `src/client/ui/hud-manager.ts`, `src/client/ui/world-panels.ts`, `src/client/view/unit-drawables.ts`, `src/client/view/scene-source.ts`, `src/client/input/command-mapper.ts`).
|
||||
This document defines the comprehensive test infrastructure, architectural contracts, test runner configuration, and execution guidelines for the Diablo II v1.13c parity test initiative (Issues #562–#712).

## 2. Complete 16-Feature Inventory (`F1`–`F16`)
|
||||
## 1. Test Architecture & Runner Setup
|
||||
|
||||
| ID | Feature | Requirement | Primary Public Contracts Under Test |
|
||||
|---|---|---|---|
|
||||
| **F1** | Canonical 1.13c Online Item Tooltip Bridge | R1.1 | `onlineItemDataToUiInventoryItem`, `HudModel.syncFromWorld()`: CHI/ENG base names, Magic/Rare/Set/Unique/Runeword names, 1H/2H damage, defense, durability, `reqLevel`/`reqStr`/`reqDex`/`reqClass`, sorted `ItemStatCost` lines (`stats`/`statsEn`), `sockets`/`usedSockets`/`socketedItems`. |
|
||||
| **F2** | C2S Container, Belt, NPC, Merc, Warp, Party & Trade Packet Encoders | R1.2, R2–R5 | `encodeD2gsClientCommand` & `clientCommandToC2sPackets` matching `C2S_PACKET_SIZES`: `0x09 WarpTo` (9B), `0x1D SwapCursorBodyItem` (`ItemSwap`, 9B), `0x1F SwapContainerItem` (17B), `0x23 BeltPut` (9B), `0x24 BeltRemove` (5B), `0x25 BeltSwap` (9B), `0x27 IdentifyItem` (9B), `0x28 SocketItem` (9B), `0x29 ScrollToBook` (9B), `0x31 QuestMessage` (9B), `0x36 HireMerc` (`MercHire`, 9B), `0x38 EntityAction` (`NpcEntityAction`, 13B), `0x41 Resurrect` (1B), `0x4F Trade` (`ClickButton`, 7B), `0x5D Hostile` (7B, `button`=1/2), `0x5E Party` (`PartyAction`, 6B), `0x61 MercItem` (3B), `0x62 NpcResurrectMerc` (`MercResurrect`, 5B). |
|
||||
| **F3** | Server-Authoritative Container, Belt, Identify, Socket & Tome UI Wiring | R1.2 | `HudModel` & `HudManager`: equip slot swap (`0x1D`) vs socket (`0x28`); container grid scroll-to-book (`0x29`), socket (`0x28`), swap (`0x1F`); belt put (`0x23`), remove (`0x24`), swap (`0x25`), shift-use on merc (`0x26` `useOnMerc=1`); right-click `isc`/`ibk` identify targeting (`0x27`). |
|
||||
| **F4** | Weapon Set II (`bodyLoc` 11 & 12) Sync | R1.3 | `HudModel.syncFromWorld()`: `bodyLoc` 11 (`rarm2`) -> `hud.inventory.swapWeapons.weapon1`, `bodyLoc` 12 (`larm2`) -> `hud.inventory.swapWeapons.weapon2`, preserved across `0x60`/`0x97` weapon switch. |
|
||||
| **F5** | Act 1–5 Town & Quest NPC Descriptors | R2.1 | `TOWN_NPC_DESCRIPTORS`, `NPC_HCIDX_TO_DESCRIPTOR_ID`, `getTownNpcDescriptorByHcIdx`: Cain (`146, 244, 245, 246, 520, 265`), Warriv (`155, 175`), Meshif (`210, 258`), Kaelan (`203`), Tyrael (`251, 367`), Hadriel (`259`), Qual-Kehk (`515`), Kashya (`150`), Greiz (`198`), Asheara (`252`), Charsi (`154`), Larzuk (`511`), Anya (`512`). |
|
||||
| **F6** | NPC Info (`0x27`), SetNPCTalk (`0x91`), Talk Submenu & `0x31 QuestMessage` | R2.2 | `ClientWorld.apply({ type: 'Npc', kind: 'info' \| 'menu' \| 'heal' })`, synchronous `NpcInit` menu opening, `Talk` submenu (`Introduction`, `Gossip`, Quest speech), `.tbl` speech dialog box, and `0x31 QuestMessage`. |
|
||||
| **F7** | Act Travel Menu Options & C2S `0x38 EntityAction` | R2.3 | `buildNpcMenuOptions` & `HudModel.handleNpcMenuAction`: `travel_east` (Warriv 155, Meshif 210), `travel_west` (Warriv 175, Meshif 258), `travel_harrogath` (Tyrael 367) emitting `NpcEntityAction` (`0x38`, 13B). |
|
||||
| **F8** | Mercenary World State (`0x4E`, `0x4F`, `0x9B` & `lifePct`) | R3.1 | `ClientWorld.apply({ type: 'Merc' })`: `hireListStart` (`0x4F`), `forHire` (`0x4E` `{ nameId, seed }`), `reviveCost` (`0x9B` `{ reviveCost, deadNameId }`), `lifePct` updates (`0x0C`, `0xAB`, `0x69`, `0x81`, `0x9E..0xA0`), and `world.containers.merc` unequip-to-cursor (`0x08`). |
|
||||
| **F9** | Mercenary Hire (`0x36`) & Resurrect (`0x62`) UI | R3.2 | `hire` option on mercenary captains (`150, 198, 252, 515`) -> `0x38` (`action=3`) -> Hire panel populated from `world.mercHireList` -> `MercHire` (`0x36`, 9B); dead merc (`reviveCost > 0`) exposes `resurrect` -> `MercResurrect` (`0x62`, 5B). |
|
||||
| **F10** | Mercenary HUD Portrait & Paperdoll (`O` Hotkey, `0x61 MercItem`) | R3.3 | Top-left mercenary portrait + life bar in `HudManager`; `'O'` hotkey toggles `'merc'` panel; `world.containers.merc` syncs to merc equipment slots (`helm`, `armor`, `weapon1`, `weapon2`); clicking slot emits `MercItem` (`0x61`, 3B). |
|
||||
| **F11** | Dungeon/Stair Warp Clicking (`0x09 AssignWarp` → C2S `0x09 WarpTo`) | R4.1 | `0x09 AssignWarp` preserves `warpId` on `UnitSnapshot` & `ClientUnit`; `buildSceneDrawables` & `ClientWorldSceneSource.pickUnitAtScreen` expose `'warp'`/`'tile'` units with localized destination labels; clicking emits `MoveToUnit` (`0x04`) + `TakeWarp`/`WarpTo` (`0x09`, 9B). |
|
||||
| **F12** | Portal Ownership Hover (`0x60`/`0x82`) & Ground Item Labels (`0x16`) | R4.2 | Town Portal (`classId` 59/60) enriched with `world.portals` (`<ownerName>'s Town Portal`, destination `areaId`); ground gold piles propagate `goldAmount` (`<N> Gold` / `<N> 金币`, never hardcoded `'1 Gold'`); `Alt` ground labels layout without overlap and click-to-pickup emits `ItemPickup` (`0x16`). |
|
||||
| **F13** | `SkillCast` (`0x4C`/`0x4D`/`0x6C`/`0x99`/`0x9A`) Animation | R4.3 | `ClientWorld.apply({ type: 'SkillCast' })` updates caster unit `castState`, facing `direction` toward target, and attack/cast animation mode (`'A1'`/`'SC'`, mode `7`/`10` for player, `4`/`7` for monster). |
|
||||
| **F14** | Player Death Overlay & C2S `0x41 Resurrect` | R4.4 | `world.self.life <= 0` (when `maxLife > 0`) or death mode sets `isDead` / `isSelfDead`, renders classic death overlay (`"You Have Died. Press ESC to continue."` / `"你挂了，请按 ESC 键继续"`), and pressing `Escape` or clicking overlay emits `{ type: 'Resurrect' }` (`0x41`, 1B). |
|
||||
| **F15** | Multiplayer Party State & Party Panel (`P` Hotkey, `0x5D`/`0x5E`) | R5.1 | `ClientWorld.apply({ type: 'Party' })` handles `roster` (`0x5B`/`0x5C`), `relation`, `memberState`, `memberPos`; `'P'` hotkey toggles `'party'` panel; Invite/Cancel/Accept/Leave emit `PartyAction` (`0x5E`, 6B); Hostile (`button=1`) and Loot (`button=2`) emit `Hostile` (`0x5D`, 7B); party portraits & automap markers. |
|
||||
| **F16** | Player-to-Player Trade UI (`0x77`–`0x79` & C2S `0x4F`) & Quest Reward Item Panels | R5.2, R5.3 | `0x77 ButtonActions`, `0x78 TradeAccepted` (`partnerName`), `0x79 GoldInTrade` (`selfGold`, `partnerGold`), `tradePartner` & `tradeSelf` 10×4 grids, Trade Accept/Cancel (`0x4F ClickButton`, 7B); Quest Reward panels (`imbue` on Charsi 154, `add_sockets` on Larzuk 511, `personalize` on Anya 512). |
|
||||

|
||||
## 2. Four-Tier Parity Test Suite Structure
|
||||
|
||||
The parity test suite is organized into four complementary verification tiers inside `tests/e2e-parity/`:
|
||||
|
||||
```
|
||||
tests/e2e-parity/
|
||||
├── helpers.ts # Shared test fixtures, mock collision oracles, item builders, and math helpers
|
||||
├── tier1-feature-coverage.test.ts # Tier 1: 48 Feature Coverage Tests (6 per batch across 8 batches)
|
||||
├── tier2-boundary-corner.test.ts # Tier 2: 48 Boundary & Edge Case Tests (6 per batch across 8 batches)
|
||||
├── tier3-cross-feature.test.ts # Tier 3: 8 Pairwise Cross-Feature Integration Tests
|
||||
└── tier4-real-world-scenarios.test.ts # Tier 4: 5 Full-Lifecycle Gameplay Scenarios
|
||||
```
|
||||
|
||||
### Tier 1: Feature Coverage (48 Tests)
|
||||
Guarantees primary positive-path behavior across all 8 subsystem batches:
|
||||
- **Batch 1 (Issues #562–#579)**: 25Hz simulation tick accumulator (40ms ticks), isometric 2:1 projection math, sub-tile conversions, and diminishing return curves.
|
||||
- **Batch 2 (Issues #580–#597)**: Universal DT1 tile loading (`Blank.dt1`, `InvisWal.dt1`, `Warp.dt1`), multi-flag collision masks, void collision blocking, and dynamic entity footprint reservation.
|
||||
- **Batch 3 (Issues #598–#615)**: Player posture modes (walk, run, town neutral, town walk), pathing waypoint queues, stamina consumption, and collision obstruction stoppage.
|
||||
- **Batch 4 (Issues #616–#633)**: DCC direction alignment (8/16/32 directions), animation clip pacing, 1.13c FCR/IAS speed formulas, and cast overlay alignment.
|
||||
- **Batch 5 (Issues #634–#651)**: DT1 block layout decoding (sub-blocks 0..24), SplitMix64 spatial hashing (no periodic stripe artifacts), Bresenham LOS raycasting, and missile projectile physics.
|
||||
- **Batch 6 (Issues #652–#669)**: Grid container placement, item bridging (`onlineItemDataToUiInventoryItem`), bilingual tooltips, belt drink commands, and weapon swap toggling.
|
||||
- **Batch 7 (Issues #670–#703)**: Authoritative C2S/S2C packet size validation, S2C movement packet parsing, Battle.net character name filtering, and corpse assignment tracking.
|
||||
- **Batch 8 (Issues #704–#712)**: Asset manifest integrity, fail-fast DT1 library audits, and headless level audit verification.
|
||||
|
||||
### Tier 2: Boundary & Corner Cases (48 Tests)
|
||||
Stress tests extreme numerical bounds, edge conditions, invalid inputs, and corrupt state:
|
||||
- Zero, negative, and fractional delta times in the simulation tick loop.
|
||||
- Extreme coordinate out-of-bounds queries clamped to `COLLIDE_BLANK | COLLIDE_WALL`.
|
||||
- Multi-layer collision bitwise flag isolation (missile barriers vs walking walls).
|
||||
- Extreme combat math limits: 0 Attack Rating, 100,000 Defense, 100% target defense reduction, 0-HP clamp, and 5% min / 95% max hit chance clamps.
|
||||
- Diminishing return caps for Faster Cast Rate (+1000% FCR clamped to 75%).
|
||||
- SplitMix64 spatial distribution across negative coordinates and coordinate mirroring.
|
||||
- Inventory boundary checks: 10x4 grid limits, overlapping 2x2 item placement rejection, and out-of-bounds slot rejection.
|
||||
- Netproto bounds: C2S packet size boundaries, corrupt 0x8E packet handling, minimum/maximum account name constraints (2 to 15 characters), and forbidden control character filtering.
|
||||
|
||||
### Tier 3: Pairwise Cross-Feature Interactions (8 Tests)
|
||||
Verifies multi-subsystem contracts across overlapping modules:
|
||||
- **X1 (Movement + Weapon Swap + Skill Cast)**: Swapping weapon sets while running updates effective cast rate and interrupts run motion upon skill cast.
|
||||
- **X2 (Collision + Teleport + Town Portal)**: Teleporting bypasses physical wall barriers and stepping into a Town Portal transitions area to town posture.
|
||||
- **X3 (Missile Trajectory + Obstacle Collision + Impact Overlay)**: Projectiles traverse open cells, impact hostile entities, and trigger visual impact overlays.
|
||||
- **X4 (S2C Server Correction + Reassign)**: Local client prediction is authoritatively corrected by S2C UnitReassign packets.
|
||||
- **X5 (Item Drop + Inventory Placement + UI Item Bridge)**: Ground drop entities enter container slots and produce properly formatted UI inventory items.
|
||||
- **X6 (Character Selection + Account Validation + Flame Anchor)**: Validates account credentials, filters character names, and aligns campfire flame anchors.
|
||||
- **X7 (Line-of-Sight Raycast + Viewport Coordinate Culling)**: Bresenham raycasting determines target visibility and culls out-of-screen render entities.
|
||||
- **X8 (Stamina / Posture Toggle + Block Chance Degradation)**: Running posture reduces player block chance by two-thirds, capped at 25%.
|
||||
|
||||
### Tier 4: Real-World Gameplay Scenarios (5 Scenarios)
|
||||
Verifies authentic full-lifecycle gameplay journeys under 1.13c ground truth:
|
||||
1. **Scenario 1 — Blood Moor Clearing**: Player departs Rogue Encampment (area 1 -> 2), transitions posture from town neutral to combat, navigates terrain obstacles, defeats Fallen, takes damage, and recovers via a belt health potion.
|
||||
2. **Scenario 2 — Den of Evil Completion**: Enters cave (area 8), reveals cavern rooms, tracks remaining monster count reaching 0, and receives Quest 0 completion bitmask from the server.
|
||||
3. **Scenario 3 — Countess Tower Run**: Descends Forgotten Tower cellars (areas 21 -> 25), battles Superunique Countess with FCR-boosted spells, slays her, and loots a guaranteed Ral Rune (`r08`) into inventory.
|
||||
4. **Scenario 4 — Tristram Rescue**: Steps through Cairn Stones Red Portal into Tristram (area 38), kites Griswold over multiple 25Hz ticks, interacts with the gibbet cage, frees Deckard Cain, and advances Quest 2.
|
||||
5. **Scenario 5 — Act Boss Kill (Andariel)**: Infiltrates Catacombs Level 4 (area 39), survives Andariel's Poison Spray, exploits her -50% Fire Resistance in Normal difficulty, slays her, triggers death overlays, completes Act 1 Quest 5, and travels with Warriv's caravan to Act 2 Lut Gholein (area 40).

## 4. Tier 4 Real-World Online Gameplay Session Scenarios
|
||||
## 3. Ground Truth Invariants & Simulation Contracts
|
||||
|
||||
1. **Scenario 1 — Town Identification, Tome Packing, Rune Socketing & Weapon Swap Loop (`F1 + F2 + F3 + F4`)**:
|
||||
- Player picks up an unidentified Unique item, right-clicks Tome of Identify (`ibk`) to arm identify targeting, left-clicks the item (`0x27 IdentifyItem`), receives server `0x9C` identified update with canonical 1.13c stats, packs loose Scroll of Identify (`isc`) into `ibk` (`0x29 ScrollToBook`), sockets a rune into a 2-socket helm (`0x28 SocketItem`), and verifies Weapon Set II (`bodyLoc` 11/12) persistence across weapon switch (`0x97`).
|
||||
2. **Scenario 2 — Belt Potion Management & Shift-Click Mercenary Feeding (`F2 + F3 + F8 + F10`)**:
|
||||
- Player places potions into belt (`0x23 BeltPut`), swaps a belt slot with a Super Healing Potion on cursor (`0x25 BeltSwap`), removes a belt potion (`0x24 BeltRemove`), and Shift-uses a belt slot (`0x26 UseBeltItem` with `useOnMerc = 1`) to heal a damaged Act 2 mercenary whose `lifePct` subsequently updates via S2C `0x0C`/`0x9E`.
|
||||
3. **Scenario 3 — Multi-Act Town NPC Dialogue, Cain Identification & Act Travel (`F2 + F5 + F6 + F7`)**:
|
||||
- Player interacts with Deckard Cain (`hcIdx` 244), opens `Talk` submenu (`Introduction`/`Gossip`/Quest speech -> `0x31 QuestMessage`), triggers Cain Identify Items (`0x38` `action=4`), then interacts with Warriv (`155` -> `travel_east` to Act 2), Meshif (`210` -> `travel_east` to Act 3), and Tyrael (`367` -> `travel_harrogath` to Act 5).
|
||||
4. **Scenario 4 — Mercenary Captain Hiring, Equipment Paperdoll (`O`) & Post-Combat Resurrection (`F1 + F2 + F8 + F9 + F10`)**:
|
||||
- Player opens Kashya (`150`) / Greiz (`198`) menu, clicks `Hire` (`0x38` `action=3`), receives `0x4F` + `0x4E` hire candidates, hires a mercenary (`0x36 HireMerc`), opens `'O'` Mercenary Paperdoll, equips/swaps merc gear (`0x61 MercItem`), takes lethal merc damage (`0x9B MercReviveCost`), and resurrects the mercenary (`0x62 NpcResurrectMerc`).
|
||||
5. **Scenario 5 — Dungeon Warp Traversal, Town Portal Ownership Hover & Ground Loot Pickup (`F2 + F11 + F12`)**:
|
||||
- Server assigns a dungeon warp tile (`0x09 AssignWarp`), player hovers/clicks warp (`0x04 MoveToUnit` + `0x09 WarpTo`), enters dungeon, hovers an allied Town Portal (`0x60`/`0x82` -> `"Sorceress's Town Portal"`), holds `Alt` to inspect non-overlapping ground labels (`750 Gold` + Magic item), and clicks to pick up (`0x16 ItemPickup`).
|
||||
6. **Scenario 6 — Combat SkillCast Animation, Player Death Overlay & Town Corpse Resurrection (`F2 + F13 + F14`)**:
|
||||
- Monster and player exchange `SkillCast` packets (`0x4C`/`0x4D`/`0x6C`) updating facing octants and `'A1'`/`'SC'` animation modes; lethal damage reduces `world.self.life` to `0`, activating `isDead` and rendering `"You Have Died. Press ESC to continue."`; pressing `Escape` dispatches `0x41 Resurrect` (1B), and server respawn restores town state.
|
||||
7. **Scenario 7 — Multiplayer Party Roster, Invite/Accept, Hostile & Corpse Loot Permissions (`F2 + F15`)**:
|
||||
- Second player joins (`0x5B` with `partyId=0xffff` and non-empty `charName`), player opens `'P'` Party panel, invites (`0x5E` `action=0x06`) and accepts (`0x5E` `action=0x08`), receives party `memberState` (`0x7F`) and `memberPos` (`0x90`) for top-left party portrait and automap marker, toggles Corpse Loot (`0x5D` `button=2`) and Hostile (`0x5D` `button=1`), and cleans up when peer leaves (`0x5C`).
|
||||
8. **Scenario 8 — Player-to-Player Trade Session & Act 1/5 Quest Reward Item Upgrading (`F1 + F2 + F5 + F16`)**:
|
||||
- Player initiates trade (`0x77` `action=0x01`), receives `tradePartner` item (`container: 'tradePartner'`) and `0x79 GoldInTrade`, places `tradeSelf` item (`container: 'trade'`), receives `0x78 TradeAccepted` with `partnerName`, clicks Trade Accept (`0x4F` `buttonId=0x04`), completes trade (`0x77` `action=0x06`), and uses Charsi `imbue` (`154`), Larzuk `add_sockets` (`511`), and Anya `personalize` (`512`) quest reward panels.
|
||||
1. **Diablo II v1.13c Ground Truth Invariant**:
|
||||
All formulas, packet sizes, collision flags, town level IDs, and animation step calculations strictly mirror 1.13c assembly from `D2Common.dll`, `D2Game.dll`, `D2Client.dll`, and `D2Launch.dll`.
|
||||
2. **Discrete 25Hz Simulation Tick**:
|
||||
Simulation logic runs on fixed 40ms intervals (`D2_TICK_MS = 40`). Sub-millisecond elapsed times accumulate until 40ms threshold is reached.
|
||||
3. **Universal DT1 Tiles**:
|
||||
Universal DT1s (`Blank.dt1`, `InvisWal.dt1`, `Warp.dt1`) are loaded unconditionally with `COLLIDE_BLANK | COLLIDE_WALL` for void safety.
|
||||
4. **SplitMix64 Spatial Hash**:
|
||||
Tile variant selection uses 64-bit SplitMix64 spatial hashing to prevent 45-degree mechanical tiling artifacts.
|
||||
5. **No Facade Tests**:
|
||||
All tests assert on real models (`ClientWorld`, `HudModel`, `CollisionGridOracle`) and verify state mutations, container contents, and packet serialization without mocking away critical domain logic.

|
||||
- X8: Stamina / Posture Toggle + Block Chance Degradation
|
||||
- **Tier 4 (5 Full Scenarios)**:
|
||||
- Scenario 1: Blood Moor Clearing (Town departure, terrain navigation, combat against Fallen, and potion recovery)
|
||||
- Scenario 2: Den of Evil Completion (Cave exploration, room visibility, monster clearing count 5 -> 0, and quest completion flag)
|
||||
- Scenario 3: Countess Tower Run (Multi-floor cellar descent 21 -> 25, superunique fight, rune drop to ground, pickup into inventory)
|
||||
- Scenario 4: Tristram Rescue (Red portal transition 4 -> 38, Griswold combat & movement kiting, Deckard Cain cage interaction & quest update)
|
||||
- Scenario 5: Act Boss Kill: Andariel (Catacombs L4 chamber entry, poison spray mechanics & vulnerability, Andariel defeat, Act 1 quest complete, Act 2 Lut Gholein transition)

* Adversarial Stress Test Harness — Batch 1 Gate (Issues #562–#576)
|
||||
*
|
||||
* Authored by Empirical Challenger (Challenger 1)
|
||||
*
|
||||
* Areas Stress-Tested:
|
||||
* 1. Missiles & Combat (#562, #568, #571, #572, #574, #576):
|
||||
* - 0-range and stationary missiles lifecycle, maxTicks calculation, and clean expiration
|
||||
* - Extreme attack rating vs defense edge cases (alvl=1 vs 99, 99 vs 1, effAr=0, effDef=0, large negative mods)
|
||||
* - 10,000-case randomized fuzzing against 1.13c integer division oracle
|
||||
* - Multiple Shot projectile count cap at slvl >= 22 (slvl 22..99 -> exactly 24 projectiles)
|
||||
* - Multiple Shot weapon ammunition branching (bow -> multipleshotarrow 213, crossbow -> multipleshotbolt 214)
|
||||
* - 1000ms deduplication window under simulated burst traffic and out-of-window packet handling
|
||||
* - Unknown missile classId fail-fast verification (#574)
|
||||
* 2. Timing & Rate Limiting (#565, #566, #573, #575):
|
||||
* - 200ms tick accumulator cap under sudden frame lag (dtMs = 1000ms, 5000ms, 100000ms)
|
||||
* - Sustained frame lag resilience (no death spiral, simulation step bounds)
|
||||
* - 100-packet non-movement command flood bypass (100% allowed, zero dropped)
|
||||
* - Movement rate-limiting preservation (120ms throttle)
