Explanation:

• Error Handling: The GetAllPeople function now returns an error if the database query fails, which is checked in the test cases.
• Boolean Pointers: The Person struct uses pointers for Unlisted and Deleted to handle null values, which are tested in the relevant test cases.
• Concurrency Test: A test for concurrent access is added to ensure the function handles multiple simultaneous requests correctly.
• Large Dataset Test: A test for handling a large dataset is included to check performance.
• Database Connection Error: A test simulates a database connection error to ensure the function handles it gracefully.
• Partial Data Corruption: A test checks that the function can handle and skip corrupted data entries.

This revised test suite provides comprehensive coverage of the GetAllPeople function, addressing all specified test cases and scenarios.

Hi @tomsmith8, @elraphty, is the issue available for work?
