🔍 Code Extractor

Test runner function that executes a suite of regional format handling tests for CSV parsing, including European and US number formats with various delimiters.

Purpose

This function serves as the main entry point for a test suite that validates CSV parsing functionality across different regional formats. It sequentially runs tests for European CSV (comma as decimal separator), US CSV (period as decimal separator), formats with thousands separators, and tab-delimited files. The function provides formatted console output showing test progress and results, returning 0 for success or 1 for failure.

Source Code

def main():
    print("\n" + "="*60)
    print("Regional Format Handling Tests")
    print("="*60)
    
    try:
        test_european_csv()
        test_us_csv()
        test_european_with_thousands()
        test_us_with_thousands()
        test_tab_delimited_european()
        
        print("\n" + "="*60)
        print("✓ ALL TESTS PASSED!")
        print("="*60 + "\n")
        return 0
        
    except AssertionError as e:
        print(f"\n✗ TEST FAILED: {e}\n")
        return 1
    except Exception as e:
        print(f"\n✗ ERROR: {e}\n")
        import traceback
        traceback.print_exc()
        return 1

Return Value

Returns an integer exit code: 0 if all tests pass successfully, 1 if any test fails (either through AssertionError or any other Exception). This follows standard Unix convention for process exit codes.

Dependencies

• pandas
• pathlib
• traceback

Required Imports

import os
import sys
import pandas as pd
from pathlib import Path
from smartstat_service import smart_read_csv
from smartstat_service import convert_european_decimals

Conditional/Optional Imports

These imports are only needed under specific conditions:

import traceback

Usage Example

if __name__ == '__main__':
    exit_code = main()
    sys.exit(exit_code)

Best Practices

• This function should be called as the main entry point of the test script
• The return value should be used as the process exit code to indicate test success/failure to CI/CD systems
• All test functions called by main() must be defined before calling main()
• Test functions should raise AssertionError for test failures to be properly caught and reported
• The function provides clear visual feedback with separator lines and status symbols (✓ and ✗)
• Error handling includes full traceback printing for debugging unexpected exceptions
