/**
|
|
* Multi-provider benchmark adapter E2E — hit real claude, codex, gemini CLIs.
|
|
*
|
|
* Periodic tier: runs under `bun run test:e2e` with EVALS=1. Each provider gated
|
|
* on its own `available()` check so missing auth skips that provider (doesn't
|
|
* abort the batch). Uses the simplest possible prompt ("Reply with exactly: ok")
|
|
* to keep cost near $0.001/provider/run.
|
|
*
|
|
* What this catches that unit tests don't:
|
|
* - CLI output-format drift (the #1 silent breakage path)
|
|
* - Token parsing from real provider responses
|
|
* - Auth-failure vs timeout vs rate-limit error code routing
|
|
* - Cost estimation on real token counts
|
|
* - Parallel execution via Promise.allSettled — slow provider doesn't block fast
|
|
*
|
|
* NOT covered here (would need dedicated test files):
|
|
* - Quality judge integration (benchmark-judge.ts, adds ~$0.05/run)
|
|
* - Multi-turn tool-using prompts — our single-turn smoke skips `toolCalls > 0`
