# LLM Tests Debugging Summary

## GitHub Workflow Issue Fixed ✅

### Problem Identified
The `.github/workflows/copilot-setup-steps.yml` had a critical step ordering issue:

**Before (BROKEN):**
1. Create `.env.llm-tests` file
2. Checkout code ← **This overwrites the directory, losing the .env file!**
3. Run tests

**After (FIXED):**
1. Checkout code
2. Create `.env.llm-tests` file ← **Now persists correctly**
3. Run tests

### Changes Made
- Moved "Persist Secrets to Agent Environment" step AFTER "Checkout code"
- Added `export` prefix to environment variables for proper shell sourcing
- Added `RUN_LLM_TESTS=true` to enable tests automatically
- Added `chmod 600` for security
- Added verification logging to confirm file creation

## Environment Setup Verification

### API Key Sourcing ✅
The `.env.llm-tests` sourcing mechanism works correctly:

```bash
# Create .env file
echo 'export OPENAI_API_KEY=sk-your-key' > .env.llm-tests
echo 'export RUN_LLM_TESTS=true' >> .env.llm-tests

# Source and verify
source .env.llm-tests
echo $OPENAI_API_KEY  # Shows the key
```

### Test Detection ✅
When the environment is properly sourced, tests correctly:
- Detect the API key presence
- Enable live test execution (not skipped)
- Show provider detection: "Running LLM integration tests with provider: openai"

### Current Limitation ⚠️
Tests fail in the jsdom environment with network errors:
```
Error: Cross origin null forbidden
Error: LLM API call failed: Network Error
```

This is expected because:
1. Tests run in a jsdom environment (not a real browser)
2. axios HTTP requests fail due to CORS restrictions in jsdom
3. Live API tests need a proper Node.js environment or network mocking

## Recommendations

### For Local Development
Run tests with a real API key in a Node environment:
```bash
source .env.llm-tests
cd app && yarn test
```

### For CI/CD
The workflow now correctly:
1. Checks out the repository first
2. Creates `.env.llm-tests` in the workspace
3. Makes the API key available to subsequent steps

Consider:
1. Running tests in a Node environment (not jsdom)
2. Using nock or msw to mock HTTP requests in tests
3. Running live tests only in scheduled jobs with proper network access

## Verified Working
- ✅ `.env.llm-tests` creation via workflow (step order fixed)
- ✅ `.env.llm-tests` creation via `setup-llm-env.sh`
- ✅ Environment variable sourcing
- ✅ Test detection of API keys
- ✅ Provider auto-detection (OpenAI/Gemini)
- ✅ Proper skip behavior when no API key

## Status
The infrastructure is now working correctly. The workflow step order has been fixed to ensure `.env.llm-tests` persists after checkout.
