# Test Failures — Iteration 371993ba

## Summary
All tests passed successfully. No failures to report.

## Test Execution Results

### Primary Tests (Acceptance Criteria Coverage)

#### 1. test_daemon_lifecycle.sh
**Status**: ✅ PASSED
**Coverage**: AC2.1, AC2.2, AC2.3
- ✓ AC2.1: Daemon starts and forks to background process
- ✓ AC2.2: Code execution through daemon returns correct output (2+3=5)
- ✓ AC2.3: Daemon shuts down cleanly with socket/PID cleanup

#### 2. test_daemon_fallback.sh
**Status**: ✅ PASSED
**Coverage**: AC2.4
- ✓ AC2.4: Fallback works when daemon not running
- ✓ Direct execution produces identical results
- ✓ Fallback continues working after daemon lifecycle

#### 3. test_error_propagation.sh
**Status**: ✅ PASSED
**Coverage**: AC2.5
- ✓ AC2.5: Error messages identical between daemon and direct execution
- ✓ Division by zero errors match
- ✓ Undefined variable errors match
- ✓ Syntax errors match
- ✓ Exit codes match for errors

### Additional Tests (Edge Cases)

#### 4. test_daemon_edge_cases.sh
**Status**: ✅ PASSED
**Coverage**: Edge cases and error handling
- ✓ Double daemon start correctly rejected
- ✓ Stop daemon when not running handled gracefully
- ✓ Empty code execution handled without crashes
- ✓ Stale socket file triggers fallback correctly
- ✓ Complex error scenarios propagate correctly
- ✓ Daemon status command works in all states
- ✓ Multiple rapid requests handled successfully

## Coverage Analysis

### Acceptance Criteria Coverage
- **AC2.1**: ✅ Fully covered by test_daemon_lifecycle.sh
- **AC2.2**: ✅ Fully covered by test_daemon_lifecycle.sh
- **AC2.3**: ✅ Fully covered by test_daemon_lifecycle.sh
- **AC2.4**: ✅ Fully covered by test_daemon_fallback.sh
- **AC2.5**: ✅ Fully covered by test_error_propagation.sh

### Edge Cases Added
The QA agent added comprehensive edge case testing:
1. **Idempotency**: Double start/stop operations
2. **Empty input**: Empty strings, whitespace, newlines
3. **State recovery**: Stale socket file handling
4. **Complex errors**: Errors in assignments, print statements, expressions
5. **Status reporting**: Daemon status in all states
6. **Concurrency**: Multiple rapid sequential requests

### Test Quality Assessment
- ✅ All tests use proper exit code checking
- ✅ All tests verify both stdout and stderr
- ✅ All tests clean up resources properly
- ✅ All tests are idempotent and can run independently
- ✅ Tests verify both positive and negative cases
- ✅ Error messages are checked for correctness
- ✅ Process lifecycle is fully verified

## No Failures Detected
All 4 test suites passed with 100% success rate.

## Recommendations
1. Consider adding performance tests to verify daemon response time
2. Consider adding stress tests with many concurrent requests
3. Consider testing daemon behavior under resource constraints
4. All core acceptance criteria are met and well-tested
