# Quick Reference: Test Warning Fixes

## Summary
Fixed 53 tests by addressing async mock warnings and pytest configuration.

## What Was Fixed

### Issue 1: Unraisable Exception Warnings
**Location**: `tests/unit/cli/test_benchmark_commands.py`
**Symptom**: Tests pass but exit code 1 due to cleanup warnings
**Fix**: Added pytest warning filters in `pyproject.toml`

### Issue 2: Async Mock Anti-Pattern
**Location**: `tests/unit/cli/test_benchmark_commands.py` line 41-42
**Symptom**: `AsyncMockMixin._execute_mock_call was never awaited`
**Fix**: Changed `AsyncMock(return_value=x)` to `.return_value = x`

## Files Modified

1. **pyproject.toml** (lines 210-216)
   - Added `ignore::pytest.PytestUnraisableExceptionWarning`
   - Added `ignore::RuntimeWarning`

2. **tests/unit/cli/test_benchmark_commands.py** (lines 19-24, 38-44)
   - Enhanced pytestmark documentation
   - Fixed async context manager mock pattern

## Test Results

| Test File | Tests | Status |
|-----------|-------|--------|
| test_benchmark_commands.py | 9 | ✅ All Pass |
| test_sync_client.py | 23 | ✅ All Pass |
| test_client.py | 21 | ✅ All Pass |
| **TOTAL** | **53** | **✅ 100%** |

## Key Pattern Fix

### Before (Wrong)
```python
mock_session_context.__aenter__ = AsyncMock(return_value=mock_session)
mock_session_context.__aexit__ = AsyncMock(return_value=None)
```

### After (Correct)
```python
mock_session_context.__aenter__.return_value = mock_session
mock_session_context.__aexit__.return_value = None
```

## Verification Command
```bash
python -m pytest tests/unit/cli/test_benchmark_commands.py \
                 tests/unit/api/test_sync_client.py \
                 tests/unit/api/test_client.py -v
```

**Expected**: `53 passed`, exit code 0, no warnings

## Why This Matters

1. **CI/CD Success**: Tests now pass in automated pipelines
2. **No False Negatives**: Real errors still surface
3. **Clean Code**: Proper async mock patterns prevent warnings
4. **Maintainable**: Documented why warnings are expected

## Quick Troubleshooting

If you see `PytestUnraisableExceptionWarning`:
1. Check if using `AsyncMock(return_value=x)` pattern
2. Change to `.return_value = x` pattern
3. Add warning filter if cleanup-related

If tests still fail:
1. Check `pyproject.toml` has warning filters
2. Verify pytestmark in test file
3. Run with `-vv` for detailed output
