v.0.2.0

0.2.0 - 2026-05-24

Fixed

• Resolve BaseOperator from airflow.sdk.bases.operator on Airflow 3,
  eliminating the DeprecatedImportWarning that came from the legacy
  airflow.models.baseoperator path. Import resolution now prefers the
  canonical Task SDK location and only falls back to the Airflow 2 path on
  Airflow 2.
• Reject concurrent run() calls on a single SubprocessPytestRunner
  instance (fail-fast with TestExecutionError) to prevent a race on the
  per-run temporary directory and process handle. Separate runner instances
  remain fully independent, and the same instance can be reused for
  sequential runs (e.g. task retries).
• cancel() no longer holds the internal lock during its graceful
  termination wait (up to grace_period seconds). The lock is now held only
  to snapshot the process handle, so on_kill no longer serializes the
  run's teardown or cleanup().
• Wrap report-directory preparation so a user-supplied report_dir pointing
  at a file (or an unwritable location) raises TestExecutionError per the
  runner contract, instead of leaking a bare OSError.

Changed

• Breaking: the test summary is now exposed only via the standard XCom
  return_value key. The previously-duplicated custom pytest_result key
  has been removed. Downstream tasks that read xcom_pull(key="pytest_result")
  must switch to xcom_pull(task_ids="<task>") (the default return_value).
• Breaking: removed the custom push_result parameter. XCom output is
  now controlled solely by Airflow's standard do_xcom_push (default True);
  pass do_xcom_push=False to disable. Replace push_result=False with
  do_xcom_push=False.

Added

• Documentation on installing the package in Docker/constrained environments
  using Airflow's official constraint files.
