    This function is responsible for setting up the testing environment and running the test suite for specific feature.

    The function performs the following tasks:
    1. Installs the required dependencies for executing any test
    2. If the `extras` parameter is provided, the function installs the additional dependencies
    3. the function runs the pytest command with the specified folders as arguments, executing the test suite.

    Parameters
    ----------
    session: nox.Session
        The current Nox session object, which is used to manage the virtual environment and execute commands.
    folders: List
        A list of folder paths that contain the test files to be executed.
    extras: Optional[str]
        A string representing additional dependencies that should be installed for the test environment.
        If not provided, the function will install the project with basic dependencies
