Unit Tests not updating states when setState is called in a callback

I'm testing a simple modal component that when you click a button to open it, a request is sent where there are two callbacks (success, error). When the success callback is called 3 states are changed:

function sucessGet(data) {
    console.log('sucessGet');
    setIsLoaded(true);
    setBody(true);
    setVisible(true);
  }

The only state that I'm testing is visible where I send as an prop to my modal.

In my test:

fit('Expect isOpen prop from AppModal to be true when successGet is called', () => {
    component = mount(<ReportModal data={dataNotReported} viewIndex={1} />);
    let AppModal = component.find('AppModal');

    console.log('Before Props', AppModal.prop('isOpen'));
    component.find('MdReportProblem').simulate('click');
    console.log('After Props', AppModal.prop('isOpen'));
  });

It calls the onClick function:

onClick={() => {
          reported ? '' : GetFraud();
        }}

That calls GetFraud:

function GetFraud() {
    console.log('getfraud');
    setIsLoaded(false);
    TransactionalAnalysisStore.GetFraudReport(eventId, sucessGet, errorGet);
  }

And when all that is done my logs are like this:

LOG: 'visible', false
LOG: 'visible', false
LOG: 'Before Props', false
LOG: 'getfraud'
LOG: 'visible', false
LOG: 'After Props', false
LOG: 'sucessGet'

After successGet is called, there is no update to my state(visible), obviously failing the test.
Can anyone give a light of hope and tell me why this is not updating the state?

Your state is not updating becasue of useState hooks works as a asyncronously. Means it takes take some time for update , use async await for it hope it will work. the beasr way to update state in useEffect() hook, just update your state on useEfect.
