From e2c92e854ffd1dfa59084c295b06baa059038e4e Mon Sep 17 00:00:00 2001 From: Kaysser Kayyali Date: Fri, 19 Jun 2026 05:59:13 +0000 Subject: [PATCH] Add unit tests for LLM clients, persona loader, and XP/Foundry rewards MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Expands the unit test suite from 320 to 380 tests (+60) and adds a Gitea Actions CI workflow. Closes all six follow-up recommendations from the test-architecture validation report. New tests (tests/unit/): - ollamaClient.test.ts — Ollama SDK wrapper, options passthrough - litellmClient.test.ts — OpenAI SDK wrapper, model fallback - personaLoader.test.ts — Zod validation + cache invalidation - foundryReward.test.ts — Tool plugin: lookup, errors, partial grants - xpAwarder.test.ts — Bulk XP awards + per-player skip reasons - redisErrorPath.test.ts — Singleton error handler does not crash - messageRouterRunLLMTurn.test.ts — 18 cases for the runtime heart: narrative-only path, tool dispatch, filter correction, retry loop guard, missed-skill-check heuristic, typing indicator interval, LLM error fallback, archive on resolve. Coverage (line %): - harness/litellmClient.ts 0 → 100 - harness/ollamaClient.ts 0 → 100 - harness/tools/foundryReward.ts 0 → 100 - session/xpAwarder.ts 0 → 100 - persona/loader.ts 0 → 100 - db/redis.ts 0 → 100 - bot/handlers/messageRouter.ts 0 → 39.86 (runLLMTurn now covered) Tooling: - package.json: + test:coverage, test:watch scripts - devDep: @vitest/coverage-v8@^3.1.0 - tests/README.md: conventions, anti-patterns, template map - .gitignore: exclude coverage/ - .gitea/workflows/test.yml: Node 22, npm cache, tsc --noEmit gate Documentation (from earlier /bmad-document-project run, now committed): - docs/index.md - docs/project-overview.md - docs/architecture.md - docs/deployment-guide.md - docs/api-contracts.md - docs/data-models.md - docs/source-tree-analysis.md - docs/component-inventory.md - docs/development-guide.md - _bmad-output/test-artifacts/automate-validation-report.md Co-Authored-By: Claude --- .gitea/workflows/test.yml | 40 + .gitignore | 1 + .../automate-validation-report.md | 291 ++++++ docs/api-contracts.md | 248 +++++ docs/architecture.md | 418 ++++++++ docs/component-inventory.md | 134 +++ docs/data-models.md | 212 ++++ docs/deployment-guide.md | 219 ++++ docs/development-guide.md | 193 ++++ docs/index.md | 55 ++ docs/project-overview.md | 106 ++ docs/source-tree-analysis.md | 190 ++++ package-lock.json | 934 +++++++++++++++++- package.json | 5 +- tests/README.md | 130 +++ tests/unit/foundryReward.test.ts | 205 ++++ tests/unit/litellmClient.test.ts | 162 +++ tests/unit/messageRouterRunLLMTurn.test.ts | 409 ++++++++ tests/unit/ollamaClient.test.ts | 103 ++ tests/unit/personaLoader.test.ts | 120 +++ tests/unit/redisErrorPath.test.ts | 75 ++ tests/unit/xpAwarder.test.ts | 162 +++ 22 files changed, 4369 insertions(+), 43 deletions(-) create mode 100644 .gitea/workflows/test.yml create mode 100644 _bmad-output/test-artifacts/automate-validation-report.md create mode 100644 docs/api-contracts.md create mode 100644 docs/architecture.md create mode 100644 docs/component-inventory.md create mode 100644 docs/data-models.md create mode 100644 docs/deployment-guide.md create mode 100644 docs/development-guide.md create mode 100644 docs/index.md create mode 100644 docs/project-overview.md create mode 100644 docs/source-tree-analysis.md create mode 100644 tests/README.md create mode 100644 tests/unit/foundryReward.test.ts create mode 100644 tests/unit/litellmClient.test.ts create mode 100644 tests/unit/messageRouterRunLLMTurn.test.ts create mode 100644 tests/unit/ollamaClient.test.ts create mode 100644 tests/unit/personaLoader.test.ts create mode 100644 tests/unit/redisErrorPath.test.ts create mode 100644 tests/unit/xpAwarder.test.ts diff --git a/.gitea/workflows/test.yml b/.gitea/workflows/test.yml new file mode 100644 index 0000000..954c313 --- /dev/null +++ b/.gitea/workflows/test.yml @@ -0,0 +1,40 @@ +name: tests + +on: + push: + branches: [main] + pull_request: + branches: [main] + +jobs: + unit: + name: Unit tests (Node 22) + runs-on: ubuntu-latest + steps: + - name: Checkout + uses: actions/checkout@v4 + + - name: Setup Node.js 22 + uses: actions/setup-node@v4 + with: + node-version: '22' + + - name: Cache npm dependencies + uses: actions/cache@v4 + with: + path: ~/.npm + key: npm-${{ runner.os }}-${{ hashFiles('**/package-lock.json') }} + restore-keys: | + npm-${{ runner.os }}- + + - name: Install dependencies + run: npm ci + + - name: Type check + run: npx tsc --noEmit + + - name: Run unit tests + run: npm run test:unit + + - name: Run coverage + run: npm run test:coverage diff --git a/.gitignore b/.gitignore index 4274b51..dd6ef19 100644 --- a/.gitignore +++ b/.gitignore @@ -1,5 +1,6 @@ node_modules/ dist/ +coverage/ .env *.log .DS_Store diff --git a/_bmad-output/test-artifacts/automate-validation-report.md b/_bmad-output/test-artifacts/automate-validation-report.md new file mode 100644 index 0000000..88e3d0b --- /dev/null +++ b/_bmad-output/test-artifacts/automate-validation-report.md @@ -0,0 +1,291 @@ +# Automate Validation Report + +> Validation of the existing Mardonar Encounter Engine test suite against the bmad-testarch-automate checklist. +> Generated 2026-06-19, validate mode. + +## ⚠️ Mismatch notice + +The bmad-testarch-automate workflow is designed for **Playwright/Cypress + Pact** test architecture (frontend E2E, API contract testing, component tests, faker-based data factories, network-first pattern).

Discord-native, LLM-driven D&D encounter engine. +> Generated 2026-06-19 from a deep scan of `/home/kaykayyali/hosting/mardonar-npcs`. + +--- + +## Executive Summary + +The Mardonar Encounter Engine is a Discord bot that runs structured D&D encounters. Each Discord thread is an encounter session. An LLM (Gemma 4 IT e2b via LiteLLM with Ollama fallback) narrates the scene, voices NPCs, drives skill checks, and steers the encounter toward hidden outcomes defined in a YAML spec. NPC memory, lore context, and encounter history are persisted in a graph database (Neo4j) accessed through a JSON-RPC MCP server (GraphMCP). Active session state lives in Redis with a TTL. The bot can also reach into Foundry VTT to resolve character stats and award XP via an external relay. + +**Key constraint:** the harness controls everything the LLM sees. The 128k context window is partitioned into hard zones (system / pinned / sliding / safety) and the assembly pipeline is deterministic. Tool calls are extracted from fenced `tool_call` JSON blocks, not via native function calling — Gemma at e2b quantization isn't reliable for native tools. + +--- + +## 1.

Three parser patterns (in order): fenced ` ```tool_call ` block, bare `tool_call` header, then a fuzzy bare-JSON fallback. Unrecognized tools or malformed args are logged and ignored — the narrative is preserved. + +The system prompt section `buildToolManifest(spec)` injects only the active set's tool definitions into the prompt contract, so each encounter's LLM only sees tools it can use. + +--- + +## 4.

Open Issues / Drift + +Items the deep scan surfaced that aren't bugs but should be tracked: + +- **Drift: `Docs/mardonar-encounter-engine.md` describes a Go bot with an embedded MCP layer; the actual code is TypeScript with an external JSON-RPC GraphMCP server.** Treat the doc as historical/aspirational. +- **Drift: `README.md`'s "Project Structure" tree references `src/mcp/` and the old `src/bot/commands/{dndname,encounter}.ts` layout.** Update README, or trim it to a pointer to the index. +- **Duplicate `trimHistory` logic** in `src/session/sessionManager.ts` and `src/harness/contextAssembler.ts` (identical body). Could be extracted to `src/lib/historyTrim.ts`. +- **No production compose file** — only `docker-compose.dev.yml`. The Dockerfile is production-ready but deployment is ad-hoc. +- **No CI/CD** — `.github/workflows/` does not exist. +- **`DISCORD_ALLOWED_USERS` is empty by default → anyone in allowed channels can run `/encounter start`.** The access control is channel-scoped, not user-scoped; admins need to set the env var explicitly. +- **`OLLAMA_BASE_URL` defaults to `localhost`** — fine for dev, but production needs the LAN IP or proxy URL set. +- **Spec tool list must be kept in sync** — `specs/*.yaml` declare `tools: [...]`, but no test verifies every referenced tool is registered. A stale spec name silently filters to no active tools. +- **Schema mismatch risk:** `types/index.ts` `EncounterSpec` and `spec/loader.ts` Zod schema have diverged slightly — `EncounterSpec` is missing `tone`, `tools`, `randomizable`, and `npcs.nameKey`. `assembleContext` reads `spec.tone`; `loader` doesn't validate it.

Set the var to enable. | +| Spec fails to load | Run `/encounter spec` for the YAML.

One module per file + +A test file covers one source module. File name: `.test.ts`, +placed under `tests/unit/`. If a source module exports multiple functions +worth testing, group them with `describe` blocks in the same file. + +### 2. Mock before import — always + +`vi.mock` calls must appear *before* the import of the module under test, +otherwise the unmocked module is already cached. The pattern: + +```ts +import { vi, describe, it, expect, beforeEach } from 'vitest'; + +const { mockFn } = vi.hoisted(() => ({ mockFn: vi.fn() })); + +vi.mock('../../src/lib/logger.js', () => ({ + log: { info: vi.fn(), warn: vi.fn(), error: vi.fn(), debug: vi.fn() }, +})); + +// ...more mocks... + +import { myFunction } from '../../src/some/module.js'; // AFTER mocks +``` + +`vi.hoisted` lets you share mock state between a `vi.mock` factory and the +test body — both run in the same scope. + +### 3. `vi.clearAllMocks()` in `beforeEach` + +Prevents test bleed-through. If you also mutate config or module-level +state, reset it explicitly in `beforeEach`. + +### 4. Reuse `mockSession` and `mockSpec` + +Import from `../fixtures/spec.js`. Don't redefine session shape per file — +schema drift is one of the easier ways for tests to silently rot. + +### 5. Test the *behavior*, not the implementation + +Assert outcomes (return values, side effects on real collaborators, error +messages) rather than calling patterns. When a test would only pass with a +specific internal implementation, ask whether the contract is what's +documented in the source's doc comment. + +### 6. Don't hit the network + +- `fetch` → use `vi.stubGlobal('fetch', ...)` (see `foundryClientRetry.test.ts`). +- Discord client → pass a hand-rolled mock with only the methods the code uses + (e.g. `messages.fetch`, `send`, `sendTyping`, `setArchived`). +- Redis → use `ioredis-mock` (see `sessionManager.test.ts`). +- LLM SDKs → mock the constructor (see `litellmClient.test.ts`, + `ollamaClient.test.ts`). +- Filesystem → use `mkdtempSync` from `node:os.tmpdir()` (see + `personaLoader.test.ts`). + +### 7. Player-facing strings + +When a test asserts on a string the bot would say to a player, prefer +in-world language over utility terms. (Same rule that applies to production +code — see `feedback-in-world-voice` memory.) + +## Anti-patterns + +- **Asserting private state.** Reach for behaviour-side assertions first. +- **Resetting state with `vi.resetModules()` for the sake of it.** It breaks + shared mock state. Use it only when a module-scoped cache (e.g. a lazy + client) needs to be re-constructed. +- **Catching all errors in a test.** If a test passes by accident because an + unhandled rejection was swallowed, it's not testing anything. +- **Mocking the module under test.** If you have to mock the file you're + testing, the test is asserting nothing. +- **Timeouts in `it()` callbacks.** Use `vi.useFakeTimers()` and + `vi.advanceTimersByTimeAsync` to step time deterministically (see + `messageRouterRunLLMTurn.test.ts` for the typing-indicator pattern). + +## Adding a new test + +1. Create `tests/unit/.test.ts`. +2. Use the closest existing test as a template — `goalRegister.test.ts` for + tool plugins, `foundryClientRetry.test.ts` for HTTP, `relaySession.test.ts` + for `node:https` / `node:crypto`, `sessionManager.test.ts` for Redis. +3. Run `npm run test:unit -- ` to iterate quickly. +4. When green, run the full suite: `npm run test:unit`. +5. Optional: check `npm run test:coverage` to confirm the file's coverage. + +## Coverage + +`npm run test:coverage` produces a v8 coverage report in the terminal. +Directories worth watching: + +- `src/bot/handlers/` — message routing; `runLLMTurn` is the runtime heart. +- `src/harness/tools/` — the tool plugin contracts. +- `src/vtt/` — Foundry relay; `foundryClient` is the biggest single file. + +Coverage is informational, not a gate.
