I have trouble testing the react function that is calling the action. below is the function –

const sendForm = () => {
    Promise.resolve(dispatch(updateBase(a,b,c)))
    .then(res => {
        if(!res.payload.errMessage){
            dispatch(fetchLogic(d,e,f))
        }
    })
}

Here is the react action that it is calling –

const updateBase = (a,b,c) => (dispatch) => {
    return apiURL.post(...)
        .then(res => dispatch(yetAnotherAction()))
        .catch(err => dispatch(errorAction()))
}

I want to test the success scenario for sendForm Function, how can we do so?
