    for more details.

-   Create a new configuration YAML file to run `pytest-langchain` with the following structure:

```yaml
    chain_file: <path to chain YAML file>
    test_cases:
    - [<input-1>, <expected output-1>]
    - [<input-2>, <expected output-2>]
    - ...
    ```

-   Run `pytest-langchain`:

```
    pytest-langchain -c <path to config YAML file> --openai-api-key <OPENAI API key>
    ```

For more options, run `pytest-langchain --help`.
