Debe usar all([...effects]) - efectos paralelos en lugar de un objeto de diccionario de la forma {label: effect, ...}

saga.ts :

 import { all, takeEvery, takeLatest } from 'redux-saga/effects'; export const actionTypes = { GET_GATEWAYS_REQUEST: 'GET_GATEWAYS_REQUEST', SELECT_GATEWAY_REQUEST: 'SELECT_GATEWAY_REQUEST', }; export function* getGatewaysFlow() {} export function* selectGatewayFlow() {} export default function* gatawayFlow() { yield all([ takeEvery(actionTypes.GET_GATEWAYS_REQUEST, getGatewaysFlow), takeLatest(actionTypes.SELECT_GATEWAY_REQUEST, selectGatewayFlow), ]); }

saga.test.ts :

 import { expectSaga, testSaga } from 'redux-saga-test-plan'; import gatawayFlow, { actionTypes, getGatewaysFlow, selectGatewayFlow } from './saga'; import { takeEvery, takeLatest } from '@redux-saga/core/effects'; describe('Unit tests', () => { test('Test all effect', () => { const saga = testSaga(gatawayFlow); saga .next() .all([ takeEvery(actionTypes.GET_GATEWAYS_REQUEST, getGatewaysFlow), takeLatest(actionTypes.SELECT_GATEWAY_REQUEST, selectGatewayFlow), ]) .next() .isDone(); }); });
