This file contains tests for the API of your model. You can run these tests by installing test requirements:

    ```bash
    pip install -r requirements-test.txt
    ```
Then execute `pytest` in the directory of this file.

- Change `NewModel` to the name of the class in your model.py file.
- Change the `request` and `expected_response` variables to match the input and output of your model.
