How to test the function correctly

I have a function that makes an API request and receives data in json format.

async function getDataAboutWeather(url) {
    return await new Promise(resolve => {
        request(url, (err, res, body) => {
            if (err) {
                throw new Error(err);
            };
            const info = JSON.parse(body);
            resolve(info);
        });
    });
};

I want to write a test for this function.

describe('getDataAboutWeather function', () => {
    it('The request should success', () => {
        const link = 'http://ip.jsontest.com';
        expect(getDataAboutWeather(link)).to.eql({});
    });
});

How to verify that my function works as it should?

Since at the moment I get an error.

AssertionError: expected {} to deeply equal {}
