dagster

hi!
How can I execute a run using a `RunRequest` instance directly from python?

I don't think you can use `RunRequest` outside of a running Dagster instance, because the Dagster instance needs to be able to pick up the `RunRequest` event and execute it for you. You can use `job_name.execute_in_process()` or <https://docs.dagster.io/_apidocs/execution#dagster.execute_job|execute_job> instead if either of those fit your needs.

I can only think of Python GraphQL client. Been using it a lot lately.

<@U0300665S8G> I guess `execute_job` will do.
My use case is testing a single run materialization for a partition range. This can be done by setting the tags argument:
```execute_job(
    ...,
    tags={
        "dagster/asset_partition_range_start": start_partition_key,
        "dagster/asset_partition_range_end": end_partition_key,
    }
)```


Indeed this is how it is tested here: <https://github.com/dagster-io/hooli-data-eng-pipelines/blob/master/hooli_data_eng_tests/test_assets.py>
On function `test_orders_multi_partition_backfill`

+1 to Zach's comment that the run request needs to be resolved and a run needs to be created and submitted by the instance.

There isn't a way to do this in a test environment currently, but you can use `execute_in_process` with the provided tags like in the code snippet you linked
