Description

Body

The dag.test is not very unit-testable, especially with executor=True - but it would be great to have some e2e tests showing that it works.

Follow up after #59314

Research direction
Examine the existing e2e testing framework in Apache Airflow, particularly how tests are structured in the 'tests' directory. Review the referenced issue #59314 to understand the context of dag.test(). Then create an e2e test that exercises dag.test() with executor=True, ensuring it works end to end. Check for any existing test infrastructure like Docker or pytest fixtures that should be used.
