How to test react-dropzone with Jest and react-testing-library?

I want to test onDrop method from react-dropzone library in React component. I am using Jest, React Testing Library. I'm creating mock file and I'm trying to drop this files in input, but in console.log files are still equal to an empty array. Do you have any ideas?

ModalImportFile.tsx

interface Props {
    isOpen: boolean;

const ModalImportFile: FC<Props & Events> = props => {
    const { isOpen } = props as Props;
    const { onClose } = props as Events;

    const [files, setFiles] = useState<Array<File>>([]);

    const { getRootProps, getInputProps, open } = useDropzone({
        onDrop: (acceptedFiles: []) => {
            setFiles(
                acceptedFiles.map((file: File) =>
                    Object.assign(file, {
                        preview: URL.createObjectURL(file),
                    }),
                ),
            );

        );
    };

    const closeHandler = () => {
        onClose();
        setFiles([]);
    };

    return (
        <Dialog open={isOpen} onClose={closeHandler}>
            <Box width={520}>
                <DialogTitle>Import</DialogTitle>
                <DialogContent>
                    <div data-testid="container" className="container">
                        <div data-testid="dropzone" {...getRootProps({ className: "dropzone" })}>
                            <input data-testid="drop-input" {...getInputProps()} />
                            {getDragZoneContent()}
                        </div>
                    </div>
                </DialogContent>
            </Box>
        </Dialog>
    );
};

export default ModalImportFile;

ModalImportFile.test.tsx

import React from "react";
import { render, screen, fireEvent } from "@testing-library/react";
import ModalImportFile from "../../components/task/elements/ModalImportFile";

const props = {
    isOpen: true,
    onClose: jest.fn(),
};

beforeEach(() => jest.clearAllMocks());

describe("<ModalImportFile/>", () => {
    it("should drop", async () => {
        render(<ModalImportFile {...props} />);

        const file = new File([JSON.stringify({ ping: true })], "ping.json", { type: "application/json" });
        const data = mockData([file]);

        function dispatchEvt(node: any, type: any, data: any) {
            const event = new Event(type, { bubbles: true });
            Object.assign(event, data);
            fireEvent(node, event);
        }

        function mockData(files: Array<File>) {
            return {
                dataTransfer: {
                    files,
                    items: files.map(file => ({
                        kind: "file",
                        type: file.type,
                        getAsFile: () => file,
                    })),
                    types: ["Files"],
                },
            };
        }
        const inputEl = screen.getByTestId("drop-input");
        dispatchEvt(inputEl, "dragenter", data);
    });
}

How about changing fireEvent(node, event); to fireEvent.drop(node, event);.
