### Suggested Improvement

there is a need to add a unit test for the project to replace the existing [python-test-samples/apigw-sqs-lambda-sqs/tests/unit/pass_test.py] file, as it currently just returns "pass" and not doing an actual unit test

Read python-test-samples/apigw-sqs-lambda-sqs/tests/unit/pass_test.py first, then trace the sample code it is intended to test. Replace the placeholder result with an assertion-based unit test for documented behavior and verify that the project's CI test job passes.
