Integration Test Guidelines

Guidelines for writing and running integration tests that make real API calls.

Approved Models

Use these models for integration tests:

Why These Models?

• •Fast: Optimized for low latency
• •Cost-effective: Cheapest tier for each provider
• •Capable: Still highly capable for test scenarios

Writing Integration Tests

Example Vibe Code

// Anthropic
model anthropic = { name: "claude-haiku-4-5-20251001", apiKey: env("ANTHROPIC_API_KEY") }

// OpenAI
model openai = { name: "gpt-5-mini", apiKey: env("OPENAI_API_KEY") }

// Google
model google = { name: "gemini-3-flash", apiKey: env("GOOGLE_API_KEY") }

Test File Location

Integration tests live in: tests/integration/

Running Integration Tests

# Run all integration tests (costs money, ~40s)
bun run test:integration

# Run a single integration test
bun test tests/integration/specific-test.test.ts

Important Notes

1. •Do NOT run full integration suite routinely - it costs money
2. •Use unit tests first - bun run test is fast and free
3. •Run targeted integration tests when verifying specific provider behavior
4. •Update model names when providers release new versions
