Pull Request Overview
This PR fixes an issue where zero-based indices were treated as falsy in get_start_and_end_position, and adds a regression test to verify parsing of an invalid token at the start of an SQL string.
- Updated the null-check in
get_start_and_end_positionto explicitly test forNone. - Added
test_invalid_token_at_beginningto cover zero-index occurrences.

- Draft comment:
Good fix: using 'is not None' avoids misinterpreting a valid zero index. This change correctly handles the case where the start position is 0. - Reason this comment was not posted:
Comment did not seem useful. Confidence is useful =0%<= threshold50%The comment is purely informative, explaining why 'is not None' is used. It doesn't provide a suggestion or ask for confirmation about the code's intention. It doesn't align with the rules for useful comments.

Consider avoiding manual sys.path insertion; setting PYTHONPATH or using proper package installation can improve test reliability.

8-9: Consider adding more test cases for completenessWhile this test covers the specific edge case of an invalid token at the beginning, it would be beneficial to add additional test cases such as:
- An invalid token in the middle of the statement
- An invalid token at the end of the statement
- Multiple occurrences of the same invalid token
- Case where invalid_string is not found

150-150: Good fix for zero-index handling!This change fixes a critical bug by explicitly checking for
Noneinstead of relying on truthiness. In Python, zero is falsy, so the previous conditionif start and end:would incorrectly skip valid indices at position 0. By changing toif start is not None and end is not None:, you ensure that zero indices are properly handled, which is essential when invalid tokens appear at the beginning of SQL statements.altimate_packages/tests/test_utils.py (1)
1-16: Well-designed regression test for the zero-index fixThis test correctly verifies the fix by testing the specific edge case where an invalid token appears at the beginning of a SQL statement (position 0). The test ensures that the function properly identifies start and end positions even when they occur at index 0, which was previously being skipped due to the bug.
