Spell::EffectForceCast always handed the forced cast the original caster as its unit target. When the triggered spell takes no unit target but does need a destination, Spell::InitExplicitTargets turns that unit target into the destination, so the forced cast resolves against the original caster instead of against the unit that was forced to cast it. Only pass the unit target when the triggered spell's explicit target mask accepts one, which is the same test InitExplicitTargets applies before discarding it. Twelve spells in the client data force-cast a spell that needs a destination but takes no unit target: 42073, 48759, 52187, 57838, 58566, 62207, 62301, 62921, 64088, 64598, 69839 and 70882. Seven of them place their summon somewhere new - 48759, 52187, 57838, 58566, 62207, 62921 and 64088, whose triggers summon at the destination itself or at a fixed offset from it. The rest do not move: 42073 force-casts on itself, 69839's force-cast effect is prevented by a spell script, and 70882's trigger overwrites the destination with TARGET_DEST_CASTER. 62301 and 64598 are the last two. Their trigger 62293 inherited the destination like the others, but a spell_info correction forcing its TargetB to TARGET_DEST_CASTER had SelectImplicitCasterDestTargets overwrite it with the forced caster afterwards, so Algalon's craters landed correctly in spite of the bug. With the root cause fixed that correction is dead code and goes with it; the fallback destination InitExplicitTargets now picks is the same position the correction used to write, so nothing moves in-game. TestEffects_ForceCastDestination covers both trigger shapes: 62221 and 62293 summoning at the destination itself, and 48757 summoning at an offset from it.

AzerothCore live-stack e2e
Protocol-level regression tests for this repository. They import
github.com/azerothcore/AzerothGhost/e2e/e2eharness
and run against a live authserver + worldserver + MySQL.
Offline go test ./... (without -tags=e2e) skips these packages.
Authoring rules for the existing suite live in the harness:
| Doc | Audience |
|---|---|
| LLM_GUIDE.md | Compact MUST/NEVER + APIs |
| EXAMPLES.md | Full recipes and skeletons |
.agents/docs/e2e-policy.md |
Do not add e2e unless asked; suite conventions |
Prerequisites
- Running AzerothCore 3.3.5a authserver + worldserver.
- MySQL with
acore_auth,acore_characters, andacore_world(world DB is required for spawn cleanup and many fixtures). - Go 1.26+ and network reachability to auth (default
127.0.0.1:3724). Warden.Enabled = 0on the worldserver, until the harness bug below is fixed upstream. Symptom: every login fails withattempted to log in using invalid client OS ().WorldSocket::HandleAuthSessionreadsaccount.osfrom the database and, when Warden is active, rejects anything that is notWinorOSX. That column is written by the authserver from the AUTH_LOGON_CHALLENGE FourCC, and AzerothGhost sends it leading-NUL first (client/auth.go:os := [4]byte{0, 'n', 'i', 'W'}), so AC's_os = os.data()builds an empty string and stores it. Docker stacks can setAC_WARDEN_ENABLED=0on the worldserver service.
Accounts are created by the harness (GM level 3, password test). Do not reuse real player accounts.
Local harness (optional)
For co-development against a local AzerothGhost checkout:
cd e2e
cp go.work.example go.work # gitignored; edit the replace path
# replace github.com/azerothcore/AzerothGhost => /path/to/AzerothGhost
e2e/go.mod pins github.com/azerothcore/AzerothGhost v1.0.8 (see go.sum).
go test / go mod download fetch that module.
Environment
Copy and adjust e2e/.env.example. Stock AC and CI use acore:acore.
| Variable | Default (harness) | Meaning |

Export vars in your shell (or set -a; source .env; set +a) before go test.
How to run
Recommended full suite (pad-safe defaults: serial tests and packages):
cd e2e
# export E2E_* from .env.example first
go test -tags=e2e ./... -count=1 -v -timeout 120m -parallel 1 -p 1
# or:
make e2e-full
-parallel 1 keeps in-package tests serial (meta.Begin is serial by default). -p 1 runs one package at a time so IsolationPads never hash-share. Raising either without a unique preferred pad per concurrent package causes thrash.
Make targets
make e2e-smoke # smoke/ + suites tagged smoke
make e2e-category C=quests # one category tree
make e2e-sub C=spells/aura # one leaf suite
make e2e-issue N=26549 # TestAC_26549_* anywhere
make e2e-tags TAGS_FILTER=smoke,short
make e2e-full # ./... long timeout
make e2e-list # list tests
Override parallel / timeout:
make e2e-full PARALLEL=1 P=1 TIMEOUT=120m
# P = go test -p (packages). Keep 1 unless every concurrent suite has a unique preferred pad.
Single test / package
go test -tags=e2e ./suites/combat/pets -count=1 -v -timeout 30m -parallel 1
go test -tags=e2e ./suites/... -run TestPets_SummonWaitDismiss -count=1 -v -timeout 15m

Parallelism and isolation
Model
| Layer | Behaviour |
|---|---|
| Packages | go test -p N runs packages concurrently. Default P=1 in the Makefile — IsolationPads has 27 unique pads; more packages than pads hash-share and can thrash. Raise P only when every concurrent package has a unique preferred pad. |
| Tests in a package | meta.Begin is serial by default (no t.Parallel). Tag parallel only if pad-safe. Makefile PARALLEL=1. |
| Pads | e2eharness.PackagePad(t) is sticky per suite folder for the process lifetime. |
Use PackagePad for combat/social placement — not a shared Stormwind cell for every suite.
pad := e2eharness.PackagePad(t)
bot.TeleportPad(t, pad)
// multi-bot:
e2eharness.FormPartyAtPad(t, pad, leader, mate)
e2eharness.TeleportAllPad(t, bots, pad)
PadStormwindOutskirts is a legacy alias of the AbandonHouse pad. Prefer PackagePad(t).
Isolation pads
Far-apart world locations (operator-captured). Combat-heavy packages have preferred 1:1 assignments; other packages take free pads or a stable hash share when the pool is exhausted.
| Pad name | Map | Notes |
|---|---|---|
Tower1 |
Eastern Kingdoms (0) | Preferred: combat/threat |
Tower2 |
Eastern Kingdoms (0) | Preferred: combat/death |
AbandonHouse |
Eastern Kingdoms (0) | Preferred: combat/pets; legacy SW outskirts alias |

Unlisted suites (smoke, spells/aura, protocol, quests, items, instances, guild, …) receive the first free pad, then hash-share if needed. Logs include PackagePad suite=… pad=….
Do not hardcode one shared coordinate for every new combat test. Content that must use a fixed world location (tabard designer, instance entrance, named tele) still may — then return to the package pad when possible.
Cleanup rules
Live e2e mutates a real realm. Cleanup is mandatory.
Persistent spawns (.npc add / .gobject add)
These write DB rows. Bare add without cleanup litters pads (e.g. Crimson Templar 15209, Gift of the Observer GO 194821).
| Do | Do not |
|---|---|
bot.Spawn / SpawnKillLootable / SpawnGameObject (register cleanup) |
Bare .npc add / .gobject add |
DespawnCreatureSpawn / DespawnGameObjectSpawn by DB spawn id |
Assume process exit cleans world DB |
| Rely on SQL DELETE + soft live despawn (harness does both) | Only live delete after socket already closed |
Despawn path: SQL DELETE always (survives session close) + optional soft .npc delete / .gobject delete while the socket is open.
Loot: do not use .npc add temp for loot tests (TEMPSUMMON_CORPSE_DESPAWN removes the corpse; use Spawn / SpawnKillLootable).
Pets, ghouls, guardians, totems
NewScenario / NewSolo register CleanupOwnedSummons on t.Cleanup (dismiss pet + despawn units with SUMMONEDBY/CREATEDBY = player).
After Raise Dead / heavy summon use, also call while still InWorld:
bot.CleanupOwnedSummons(t)
SoftPass (fail-closed)
SoftPass / SoftPassf fail the test by default so unjudgeable fixtures cannot greenwash CI. Only local debug:
E2E_ALLOW_SOFT_PASS=1 go test -tags=e2e …
Prefer Preconditionf (setup blocked), Assertf / ConfirmedBugf (oracle), or HarnessFailf (infra).

Common flakes and fixes
| Symptom | Likely cause | Fix |
|---|---|---|
| NPC ignores bot / no aggro | GM mode still on | CombatReady / CombatReadyFull before pull |
| Boss resets mid-fight | .gm on for .damage |
Damage / DamageKill (mode off) |
Melee out of range after .tele |
Named tele short of target | GoCreatureID after TeleNamed |
| Unit not in cache after tele | Cache clear on transfer | Re-WaitUnit after tele / WaitInWorld |
| Random combat on pad | Leftover spawns / pets / other package thrash | Cleanup helpers; -parallel 1; PackagePad |
| Cast fails “in combat” on empty pad | Contested pad / leftover temp | CombatStop; despawn litter; unique pad |
| Loot roll never starts | Wrong creature or threshold | CreatureGroupLootFixture (15209) + LootThresholdUncommon |
| Quest status wrong in DB | Asserted before save | Save / QuestStatusAfterSave |
| GM commands silently ignored | Wrong race language | Set Race on bot (harness uses racial language) |
SOFT-PASS disabled fatal |
SoftPass without opt-in | Use real severity helpers, or E2E_ALLOW_SOFT_PASS=1 locally only |
precondition: spam |
Stack/DB/env mismatch | Check E2E_*, world up, DSN DB names |
| Intermittent pass without code change | Sleeps / races | Replace sleeps with waiters; fix Arm→Send→Wait |
A test that fails intermittently on a correct core is a test/harness bug until proven otherwise. Do not hide flakes with longer sleeps or SoftPass.

Policy
Do not add e2e tests unless asked. Do not mention missing coverage unless the user asked about it.
.agents/docs/e2e-policy.md is suite convention when changing existing tests. This README is
how to run and structure the suite.
CI
Details live in the workflow files only:
.github/workflows/e2e-live.yml,
.github/workflows/core-build-nopch.yml.
| How | Effect |
|---|---|
| Non-draft PR in azerothcore/azerothcore-wotlk | nopch ubuntu-24.04/clang-18 compiles + dry-run, then full e2e reuses those binaries |
Merge to master |
same clang-18 nopch build, then full e2e again (flake + merge-base drift) |
Actions → e2e-live → Run workflow (official repo; needs workflow on default branch, or gh workflow run … --ref e2e) |
Compiles on the runner; choose scope (smoke/full) |
Day-to-day development should use a local stack and the committed suites, not CI setup docs.
