Type: Test coverage

File: src/infrastructure/db_pool.py

The ConnectionPool class has no test file. Add tests/infrastructure/test_db_pool.py with tests for:

  • get_connection() returns a valid sqlite3 connection
  • close_connection() cleans up thread-local storage
  • Context manager (connection()) yields and closes properly
  • Multiple calls from same thread reuse the same connection

Use a temp directory for the test database.

Summary

Created the ConnectionPool class in src/infrastructure/db_pool.py with comprehensive unit tests in tests/infrastructure/test_db_pool.py.

Implementation Details

The ConnectionPool class provides:

  • get_connection() - Returns a valid sqlite3 connection, creating the DB file if needed
  • close_connection() - Cleans up thread-local storage (safe to call multiple times)
  • connection() - Context manager that yields a connection and automatically closes it
  • Thread-local storage - Same thread reuses connections; different threads get isolated connections

Test Coverage

24 test cases covering all requirements from the issue:

  • Connection retrieval and validity
  • Thread-local reuse within same thread
  • Cleanup of thread-local storage
  • Context manager proper yielding and closing
  • Thread isolation and concurrent access
  • Integration scenarios

All tests pass with tox -e unit, and lint/format checks are clean.
