/**
* Complete OpenAI GPT + MCP Integration Tests
*
* REQUIREMENTS TO RUN THESE TESTS:
* 1. Valid Google OAuth credentials file at path specified by GOOGLE_OAUTH_CREDENTIALS env var
* 2. Authenticated test account: Run `npm run dev auth:test` first
* 3. OPENAI_API_KEY environment variable set to valid OpenAI API key
* 4. TEST_CALENDAR_ID, INVITEE_1, INVITEE_2 environment variables set
* 5. Network access to both Google Calendar API and OpenAI API
*
* These tests implement a full end-to-end integration where:
* 1. OpenAI GPT receives natural language prompts
* 2. GPT selects and calls MCP tools
* 3. Tools are executed against your real MCP server
* 4. Real Google Calendar operations are performed
* 5. Results are returned to GPT for response generation
*
* DEBUGGING:
* - When tests fail, full LLM interaction context is automatically logged
* - Set DEBUG_LLM_INTERACTIONS=true to log all interactions (not just failures)
* - Context includes: prompt, model, tools, OpenAI request/response, tool calls, results
*
* WARNING: These tests will create, modify, and delete real calendar events
* and consume OpenAI API credits.
