+# --- Alternative Method to Modify sys.path for Testing ---
+# This approach is used to allow importing main.py, which is located in the project's root directory,
+# when such tests rely on running the application entry point.
+# Note: main.py defines a main() function and runs it if executed directly by the user.
+# Modifying sys.path is less ideal because it involves changing the import path at runtime, which can lead to
+# maintenance issues or conflicts with the module namespace.

+# # Uncomment the line below to update sys.path, adding the project root directory.
+# import sys
+# sys.path.insert(0, os.path.abspath(
+#     os.path.join(os.path.dirname(__file__), '..')
