How to call a call back function in action's payload

[vandiepbui]

Hi,

I have a callback function in payload. Please tell me how to call that callback function when testSaga.

My saga.js
export const sumTwoNumbers = function* ({ payload: { a, b, onSuccess } }) {
try {
let sum = a + b;
yield put(sumTwoNumbersSuccess());
yield call(onSuccess(sum));
} catch(e) {
console.log(e)
}
};

My saga.test.js

describe('sum two numbers', () => {
const actionPayload = {
type: 'SUM_TWO_NUMBER',
payload: {
a: 5,
b: 6,
onSuccess: () => 11,
},
};

it('should sum two numbers success', () => {
testSaga(sumTwoNumbers, actionPayload)
.next()
.put(sumTwoNumbersSuccess())
.next()
.isDone();
});
});

I want to call onSuccess function in unit test.
Please help me!
Thanks so much!
