Working on a single package? `cd packages/<pkg>` and use its scripts directly (`pnpm test:lib`, `pnpm test:types`, etc.).

### Faster local runs

Root `pnpm test`, `pnpm test:pr`, and `pnpm test:lib` set `VITEST_MAX_WORKERS=1`. Nx runs 4 tasks at a time (`nx.json` `parallel`). Together that stops each package from spawning one Vitest worker per CPU core while 15 packages already run in parallel.

A single package still uses all cores:

```bash
cd packages/ai
pnpm test:lib
```

Local `pnpm test:e2e` runs openai, anthropic, and gemini. Features that none of those support (TTS, image-gen, and similar) still run on the providers that do. CI always runs the full matrix.

```bash
E2E_PROVIDERS=* pnpm test:e2e # full matrix locally
E2E_PROVIDERS=grok pnpm test:e2e # one provider
```

Playwright does not retry or record video locally. CI retries twice and keeps the video of a failed test.

## TypeScript configuration

There is a single `tsconfig.base.json` at the repo root with the shared `compilerOptions`. Every package extends it and overrides only what's unique to that package (e.g. `outDir`, JSX runtime, framework lib).

**Architecture:** Playwright drives a TanStack Start app (`testing/e2e/`) which routes requests through provider adapters pointing at aimock. Fixtures define mock responses. No real API keys needed. All scenarios (including tool execution flows) use aimock fixtures. Tests run in parallel with per-test `X-Test-Id` isolation.

**Providers tested:** openai, anthropic, gemini, vertex, vertex-grok, vertex-mistral, ollama, groq, grok, openrouter, openrouter-responses, vercel-gateway, vercel-gateway-responses, lovable, lovable-responses, bedrock, bedrock-responses, openai-compatible, openai-compatible-legacy, mistral, byteplus, elevenlabs, llmgateway, cloudflare
**Providers tested in CI:** openai, anthropic, gemini, vertex, vertex-grok, vertex-mistral, ollama, groq, grok, openrouter, openrouter-responses, vercel-gateway, vercel-gateway-responses, lovable, lovable-responses, bedrock, bedrock-responses, openai-compatible, openai-compatible-legacy, mistral, byteplus, elevenlabs, llmgateway, cloudflare

**Local `pnpm test:e2e`** runs openai, anthropic, and gemini. Features that none of those support still run on the providers that do. Use `E2E_PROVIDERS=*` for the full matrix, or `E2E_PROVIDERS=grok` (comma-separated) to pick providers. Playwright does not retry or record video locally; CI retries twice and keeps the video of a failed test.

> **Claude Code (`@tanstack/ai-claude-code`) is excluded from the standard matrix.** It's a harness adapter that spawns the Claude Code runtime as a subprocess, so aimock's per-test `X-Test-Id` header isolation can't be injected into its requests. It's covered by unit tests in the package plus a gated live smoke test in `tests/claude-code.spec.ts` — run it with `CLAUDE_CODE_E2E=1` and an `ANTHROPIC_API_KEY` (or a local `claude login`).

Playwright test video retain-on-failure records video every test official documentation

💡 Result:

In Playwright, the 'retain-on-failure' mode for video recording is a configuration option that balances the need for failure evidence with storage efficiency [1]. When you set video: 'retain-on-failure' in your configuration, Playwright records a video for every test run but automatically deletes the recordings for any tests that pass [2][3]. If a test fails, the video file is preserved in your test output directory (typically 'test-results') [2][4]. You can enable this by adding the option to the use object within your playwright.config.ts (or.js) file: import { defineConfig } from '@playwright/test'; export default defineConfig({ use: { video: 'retain-on-failure', }, }); It is important to note that because Playwright cannot predict whether a test will fail before it begins, this mode still incurs the performance overhead of recording every test during execution [1]. If you need to avoid the recording overhead on the "happy path" entirely, you might consider alternatives like 'on-first-retry' (if your configuration includes retries), which only records the test during its retry attempt [3][1]. For more granular control, the video option can also accept an object, though the 'retain-on-failure' shorthand is the standard way to achieve this behavior [3][5]. Recordings are saved upon the closure of the browser context at the end of each test, so ensure any manually created browser contexts are properly closed [2][4].

video: 'retain-on-failure' records every test and deletes videos only for passing tests. Set video to process.env.CI ? 'retain-on-failure' : 'off' to avoid local recording overhead.

Restrict explicit E2E_PROVIDERS selections to the selected providers.

When E2E_PROVIDERS=elevenlabs, providersFor('image-gen') returns every supported image-generation provider because filtered is empty and line 85 falls back to supported. Return the empty selection for explicit provider lists, or fail with a clear message. The fallback should apply only to the implicit local default.
