PYTHON-5791

Changes in this PR

Latest server version changed the order of databases returned by test_list_database_names. Our test explicitly checks for order despite the spec not requiring it to do so. Requiring identical ordering is both fragile and does not affect correctness.

Test Plan

Changed test to verify contents only and not ordering.

Pull request overview

This PR updates the synchronous and asynchronous test_list_database_names tests to avoid asserting on database ordering, which can vary across server versions and is not required by the specification.

Changes:

  • Replace assertEqual(db_names, cmd_names) with assertCountEqual(db_names, cmd_names) in the synchronous client test.
  • Apply the same change to the asynchronous client test.

Reviewed changes

Copilot reviewed 2 out of 2 changed files in this pull request and generated no comments.

File Description
test/test_client.py Makes test_list_database_names order-insensitive by comparing contents only.
test/asynchronous/test_client.py Mirrors the order-insensitive assertion change for the async client test.
