# issue-12-bug-fixes-verification: Verify all 681 tests pass after bug fixes

## Description
Run comprehensive test suite after all bug fixes to ensure 681/681 tests passing (100% pass rate). Validates that all 14 bugs are fixed (7 function parameter bugs, 2 negative number parsing bugs, 5 benchmark stability issues) and no regressions introduced to the 664 currently passing tests.

## Architecture Reference
Read architecture.md Section "Phase 4: Bug Fixes (14 Tests)" for:
- Complete list of 14 failing tests with expected behaviors
- Testing strategy for individual test validation
- Test output parsing commands for verification
- Benchmark coefficient of variation (CV) requirements

## Interface Contracts
- **Script Output**: Exit code 0 = all tests pass, exit code 1 = failure
- **Test Command**: `cargo test --release` → must show "681 passed; 0 failed"
- **Validation**: Parse output for "test result:" line containing "681 passed"

## Files
- **Create**: `scripts/validate_test_status.sh` (test count parser and validator)

## Dependencies
- issue-07-function-parameter-bug-1 (provides: Fixed test_function_call_with_expression_args)
- issue-08-function-parameter-bug-2 (provides: Fixed test_function_calling_before_definition)
- issue-09-function-parameter-bug-3 (provides: Fixed test_function_calling_convention_multiple_args)
- issue-10-function-parameter-bug-4 (provides: Fixed test_function_using_param_in_multiple_operations)
- issue-11-function-parameter-bug-5 (provides: Fixed test_function_with_multiple_return_paths_early_return)
- issue-13-negative-number-parsing (provides: Fixed negative number tests)
- issue-14-benchmark-stability (provides: Fixed 7 benchmark CV tests)

## Provides
- Verified 100% test pass rate (681/681)
- Confirmation all bugs fixed with no regressions
- Automated validation script for CI integration

## Acceptance Criteria
- [ ] AC4.1: `cargo test --release` exits with code 0 showing 681/681 tests passed
- [ ] AC4.2: All 664 tests that currently pass still pass (no regressions)
- [ ] M4: 14 failing tests now pass, total 681/681 tests passing

## Testing Strategy

### Test Files
- All test files in `tests/*.rs`: Validate complete test suite execution
- `benches/*.rs`: Verify benchmark stability (CV < 10%)

### Test Categories
- **Regression validation**: Run `cargo test --release` and verify exit code 0
- **Count validation**: Parse test output for "681 passed; 0 failed" string
- **Individual test checks**: Run each of 14 specific tests in isolation to confirm fixes

### Run Command
```bash
# Run full test suite
cargo test --release 2>&1 | tee test_output.txt

# Validate with script
./scripts/validate_test_status.sh test_output.txt

# Exit code 0 = 681/681 passed, 1 = failures detected
```
