+DAG testing
+===========
+
+To ease and speed up process of developing DAGs you can use
``InProcessExecutor`` - a single
+threaded executor for debugging purposes. Using this executor you can run and
debug DAGs
+from your IDE.
+
+**IDE setup steps:**
+
+1. Add main at the end of your DAG file to make it runnable:
+
+ .. code-block:: python
+
+ if __name__ == '__main__':
+ dag.clear(reset_dag_runs=True)
+ dag.run()
+
+ By adding this running a DAG file will run a backfill job.
+
+2. Setup ``AIRFLOW__CORE__EXECUTOR=InProcessExecutor`` in run configuration of
your IDE. In
+ this step you should also setup all environment variables required by your
DAG.
+
+3. Run the DAG file.
