1-10: Useful version checking utility but missing best practices

This script provides a helpful way to verify PyGithub installation and Python version, which is valuable for troubleshooting. However, it could be improved by structuring the code within a main function and adding a if __name__ == "__main__": guard.

src/backend/exceptions.py (1)

1-15: Good exception hierarchy with clear purpose

The custom exception classes are well-defined with descriptive docstrings. Each exception corresponds to a specific type of error that can occur during GitHub integration operations.

Consider enhancing the exceptions to include more detailed error information:

class GitHubAuthError(Exception):
    """Raised when GitHub authentication fails"""
-    pass
+    def __init__(self, message="GitHub authentication failed", details=None):
+        self.details = details
+        super().__init__(message)

class WebhookError(Exception):
    """Raised when webhook processing fails"""
-    pass
+    def __init__(self, message="Webhook processing failed", details=None):
+        self.details = details
+        super().__init__(message)

class RepositoryError(Exception):
    """Raised when repository operations fail"""
-    pass
+    def __init__(self, message="Repository operation failed", details=None):
+        self.details = details
+        super().__init__(message)

class PRError(Exception):
    """Raised when pull request operations fail"""
-    pass
+    def __init__(self, message="Pull request operation failed", details=None):
+        self.details = details
+        super().__init__(message)

This modification would allow you to pass additional context when raising these exceptions, making debugging easier.

• Option to disable automatic browser opening

        # ... browser opening code ...

177-187: Consider using a standard testing framework.

The script is using a manual test runner rather than leveraging a standard testing framework. This makes it harder to maintain and expand the tests in the future.

Consider converting this to use pytest or unittest for better test organization and reporting:

-if __name__ == "__main__":
-    # Run the tests
-    test_webhook_handler_init()
-    test_verify_webhook_valid()
-    test_verify_webhook_invalid()
-    test_handle_event_unsupported()
-    test_handle_pull_request_opened()
-    test_handle_issue_opened()
-    test_handle_push()
-    print("All tests passed!")
+if __name__ == "__main__":
+    import unittest
+    
+    # Create a test suite
+    def suite():
+        suite = unittest.TestSuite()
+        suite.addTest(unittest.FunctionTestCase(test_webhook_handler_init))
+        suite.addTest(unittest.FunctionTestCase(test_verify_webhook_valid))
+        suite.addTest(unittest.FunctionTestCase(test_verify_webhook_invalid))
+        suite.addTest(unittest.FunctionTestCase(test_handle_event_unsupported))
+        suite.addTest(unittest.FunctionTestCase(test_handle_pull_request_opened))
+        suite.addTest(unittest.FunctionTestCase(test_handle_issue_opened))
+        suite.addTest(unittest.FunctionTestCase(test_handle_push))
+        return suite
+    
+    # Run the tests
+    runner = unittest.TextTestRunner()
+    runner.run(suite())

Or better yet, refactor to use pytest classes for better organization:

import pytest

class TestWebhookHandler:
    def test_webhook_handler_init(self):
        # Test code...
        
    def test_verify_webhook_valid(self):

    # Verify the GitHub client was called
