Summary of Changes

Hello, 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!

This pull request refines the test execution configuration for dynamically generated ML preprocessing tests. By adjusting where the no_xdist marker is applied, the change ensures that tests requiring specific environment isolation are correctly handled during parallel test execution.

Highlights

• Test Configuration Update: Moved the no_xdist pytest marker from the general Python dependency check to the specific cloud environment check in the YAML examples test suite.

Code Review

This pull request adjusts the placement of the pytest.mark.no_xdist decorator within the _python_deps_involved conditional block in examples_test.py, moving it to the end of the decorator chain. I have no feedback to provide.
