Tests in scripts/ fail on Python 3.12 due to incorrect use of called_once_with

[avirajsingh7]

Describe the bug
When running tests using Python 3.11, everything passes without issues.
However, when running the same test suite on Python 3.12, all tests inside the scripts/ folder fail with the following error:

scripts/test_test_pre_start.py::test_init_successful_connection - AttributeError: 'called_once_with' is not a valid assertion. Use a spec for the mock if 'called_once_with' is meant to be an attribute.. Did you mean: 'assert_called_once_with'?

To Reproduce
Steps to reproduce the behavior:

• Run tests using Python 3.12:

cd backend/app/tests
pytest -v scripts

• Observe that tests fail with AttributeError related to called_once_with.
• Run the same using Python 3.11 and see that it passes.

Expected behavior
Tests should behave consistently across Python versions.
