We are lacking test coverage of [`batch_run`](https://github.com/projectmesa/mesa/blob/main/mesa/batchrunner.py) in CI. Especially more example models using batch_run in CI could be useful. See https://github.com/projectmesa/mesa-examples/issues/126 and https://github.com/projectmesa/mesa/pull/2183.
