Óscar Fonseca 4a371d1d9f fix(usage): preserve nested cached_tokens in canonicalizeUsage
buildUsage() only emits cache reads under prompt_tokens_details, so the
top-level-only read dropped the count for every Responses-format provider
(codex, grok-cli, ...), persisting cached_tokens: 0 and billing cache hits
at the full input rate. Mirror the cache_creation fallback already used
just above.

9Router Embeddings Tests

Unit tests for the /v1/embeddings endpoint implementation.

Setup

Install test dependencies from the tests/ directory:

cd tests/ && npm install

Running Tests

From the tests/ directory:

npm test

Or run vitest directly with npx:

npx vitest run --reporter=verbose --config ./vitest.config.js

Test Files

File What it tests
unit/embeddingsCore.test.js open-sse/handlers/embeddingsCore.js — core logic: body builder, URL router, headers, handler flow
unit/embeddings.cloud.test.js cloud/src/handlers/embeddings.js — cloud worker handler: auth, validation, rate limits, CORS

Coverage Summary (59 tests)

embeddingsCore.test.js (36 tests)

  • buildEmbeddingsBody: single string, array, encoding_format, default float
  • buildEmbeddingsUrl: openai, openrouter, openai-compatible-*, unsupported providers
  • buildEmbeddingsHeaders: per-provider header sets, fallback to accessToken
  • handleEmbeddingsCore input validation: missing, wrong type, null, empty
  • handleEmbeddingsCore success: response format, CORS, Content-Type, callbacks
  • handleEmbeddingsCore errors: 400/429/500, network error, invalid JSON
  • handleEmbeddingsCore token refresh: 401 retry, graceful fallback

embeddings.cloud.test.js (23 tests)

  • CORS OPTIONS: 200 response, empty body, correct headers
  • Authentication: missing key, bad format, old-format key, wrong key value, valid key
  • Body validation: invalid JSON, missing model, missing input, bad model
  • Happy path: single string, array, correct delegation, CORS header, machineId override
  • Rate limiting: all accounts rate-limited → 503 + Retry-After, no credentials → 400
  • Error propagation: non-fallback errors passed through, 429 exhausts accounts
  • machineId override: validates key, rejects wrong key
