mockfirebase ref is not a function

[RezaRahmati]

Hi

I have below code in my test with jest

    import {MockFirebase} from 'firebase-mock';

    mockfirebase = new MockFirebase();
    mockfirebase.autoFlush();
    const ref = mockfirebase.ref('test');

but I get TypeError: mockfirebase.ref is not a function

Also when I console.log(typeof mockfirebase.ref); it will show object instead of function. What I am doing wrong?
