# Phase 8.5 Testing Guide

## Summary

This phase resolved 27 test failures by:
1. Removing all `chmod` calls from source code (blocked at kernel level in fish tank)
2. Removing config-file API key support (environment variables only)
3. Fixing LangChain mock setup in mission generator tests
4. Cleaning up dead conftest helpers
5. Clearing stale Hypothesis cache

## Automated Testing

Run the full test suite:
```bash
pytest --tb=short -q
```

Expected result: **717 tests passing**

Key test files modified:
- `tests/test_config.py` — Removed chmod-based tests, updated API key resolution tests
- `tests/test_mission_generator.py` — Fixed mock setup using `mock_mission_chain`
- `tests/test_conftest_helpers.py` — Removed dead helper tests

## Manual Testing

### 1. Verify chmod removal
```bash
grep -r "chmod" src/
```
Expected: No matches in `.py` files (only bytecode cache matches possible)

### 2. Verify API key resolution
```bash
# Without any env vars, should fail
python3 -c "
from unfamiliar.config import UnfamiliarConfig, resolve_api_key
config = UnfamiliarConfig()
try:
    resolve_api_key('anthropic', config)
except Exception as e:
    print(f'Expected error: {type(e).__name__}')
"

# With env var, should succeed
ANTHROPIC_API_KEY=test-key python3 -c "
from unfamiliar.config import UnfamiliarConfig, resolve_api_key
config = UnfamiliarConfig()
key = resolve_api_key('anthropic', config)
print(f'Got key: {key[:8]}...')
"
```

### 3. Verify config file ignores api_keys section
```bash
python3 -c "
import tempfile
from pathlib import Path
from unfamiliar.config import load_config

with tempfile.TemporaryDirectory() as tmpdir:
    config_path = Path(tmpdir) / 'config.toml'
    config_path.write_text('''
[general]
provider = \"anthropic\"

[api_keys]
anthropic = \"sk-this-should-be-ignored\"
''')
    config = load_config(config_path)
    print(f'api_keys: {config.api_keys}')
    assert config.api_keys == {}, 'api_keys should be empty'
    print('PASS: api_keys section is ignored')
"
```

## Edge Cases

1. **Empty api_keys in config** — Should work, returns empty dict
2. **Missing env vars** — Should raise `APIKeyError`
3. **Hypothesis cache cleared** — Property tests should pass consistently
