An extensive test suite is included to test the library behavior and several examples. Library tests can be found in
the [tests folder](https://github.com/huggingface/diffusers/tree/main/tests).  
We like `pytest` and `pytest-xdist` because it's faster. From the root of the
repository, here's how to run tests with `pytest` for the library:  
```bash
$ python -m pytest -n auto --dist=loadfile -s -v ./tests/
```  
In fact, that's how `make test` is implemented!
