🔍 Code Extractor

Orchestrates a comprehensive SharePoint connection diagnostic tool that validates Azure AD authentication and SharePoint access by running multiple tests and reporting results.

Purpose

This function serves as the entry point for a diagnostic tool that verifies SharePoint connectivity. It loads configuration, displays connection parameters, executes authentication tests (Azure token and SharePoint token), and provides detailed feedback on test results with troubleshooting guidance. Returns 0 on success or 1 on failure, making it suitable for use as a CLI tool exit code.

Source Code

def main():
    """Run all diagnostics."""
    print("SharePoint Connection Diagnostic Tool")
    print("=" * 50)
    
    config = load_config()
    if not config:
        print("❌ Could not load configuration")
        return 1
    
    print(f"SharePoint Site: {config.get('SHAREPOINT_SITE_URL', 'Not set')}")
    print(f"Client ID: {config.get('AZURE_CLIENT_ID', 'Not set')[:8]}...")
    print(f"Client Secret: {'Set' if config.get('AZURE_CLIENT_SECRET') else 'Not set'}")
    print()
    
    # Run tests
    tests_passed = 0
    total_tests = 2
    
    if test_azure_token():
        tests_passed += 1
    
    if test_sharepoint_token():
        tests_passed += 1
    
    print("\n" + "=" * 50)
    print(f"Diagnostic Results: {tests_passed}/{total_tests} tests passed")
    
    if tests_passed == total_tests:
        print("🎉 All diagnostics passed! SharePoint connection should work.")
        return 0
    else:
        print("❌ Some diagnostics failed. Please check the guidance above.")
        print("\n📋 Common Solutions:")
        print("1. Verify Azure AD app permissions (Sites.Read.All)")
        print("2. Ensure admin consent is granted")
        print("3. Check client ID and secret are correct")
        print("4. Verify SharePoint site URL is accessible")
        return 1

Return Value

Returns an integer exit code: 0 if all diagnostic tests pass successfully, or 1 if any tests fail or configuration cannot be loaded. This follows standard Unix exit code conventions where 0 indicates success.

Required Imports

import os
import sys

Usage Example

# Assuming load_config(), test_azure_token(), and test_sharepoint_token() are defined
# and environment variables or config file are set up

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

# Or simply:
# python diagnostic_tool.py
# The function will print diagnostic results and return appropriate exit code

Best Practices

• This function depends on three external functions: load_config(), test_azure_token(), and test_sharepoint_token() which must be defined in the same module
• Use the return value as a system exit code for proper CLI integration
• Ensure Azure AD application has proper permissions (Sites.Read.All) before running
• The function prints sensitive information (partial client ID), ensure output is not logged in production
• Configuration should be stored securely, preferably using environment variables or encrypted config files
• The function assumes exactly 2 tests; if adding more tests, update the total_tests variable accordingly
