Summary of Changes
Hello @robfrank, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
I've added a new test case to ensure our driver correctly handles named parameterized Cypher queries when using the psycopg2 interface. This enhancement verifies that parameters are properly substituted, improving the robustness of our query execution.
Highlights
- New Test for Cypher Query Parameterization: I've introduced test_psycopg2_with_named_parameterized_cypher_query in e2e-python/tests/test_arcadedb.py. This test specifically validates that the driver correctly processes and substitutes named parameters within Cypher queries executed via the psycopg2 driver.

Code Review
This pull request adds a test for named parameterized Cypher queries. The implementation is mostly correct, but I've found a couple of areas for improvement. The test's docstring should be more specific to Cypher queries for clarity. More importantly, the assertion in the new test is likely incorrect because of how results from a RETURN <node> Cypher query are structured, and I've suggested a fix. Please see my detailed comments.
| query_params = {'name': 'Stout'} | ||
| cursor.execute('{cypher} MATCH (b:Beer) WHERE b.name =%(name)s RETURN b', query_params) | ||
| beer = cursor.fetchall()[0] | ||
| assert 'Stout' in beer |

The Cypher query RETURN b results in a single-column result set. cursor.fetchall()[0] assigns the first row (a single-element tuple) to beer. The assertion assert 'Stout' in beer incorrectly checks for 'Stout' as an element of this tuple. To fix this, the assertion should check for 'Stout' within the node representation, which is the first element of the beer tuple (beer[0]).
| assert 'Stout' in beer | |
| assert 'Stout' in beer[0] |

The docstring is a copy from the preceding SQL test. For better clarity and maintainability, please update it to reflect that this test is for a Cypher query.

#2114
This pull request adds a new test to ensure that the driver correctly handles named parameterized Cypher queries using the psycopg2 interface. This helps verify that named parameters are properly substituted in Cypher statements.
Testing improvements:
test_psycopg2_with_named_parameterized_cypher_queryto validate support for named parameters in Cypher queries executed via the psycopg2 driver (test_arcadedb.py).
