Tengo un generador que quiero cubrir con unit-test
export default function* gatawayFlow() { yield all([ takeEvery(actionTypes.GET_GATEWAYS_REQUEST, getGatewaysFlow), takeLatest(actionTypes.SELECT_GATEWAY_REQUEST, selectGatewayFlow), ]); }Escribí una prueba simple con redux-sag-test-plan
import {expectSaga, testSaga} from 'redux-saga-test-plan'; import gatawayFlow, {getGatewaysFlow, selectGatewayFlow} from '../logic/sagas'; import * as actions from '../logic/actions'; import * as actionTypes from '../logic/actionTypes'; import {takeEvery, takeLatest} from '@redux-saga/core/effects'; // Unit-test describe('Unit tests', () => { test('Test all effect', () => { const saga = testSaga(gatawayFlow); saga .next() .all({ [actionTypes.GET_GATEWAYS_REQUEST]: takeEvery(actionTypes.GET_GATEWAYS_REQUEST, getGatewaysFlow), [actionTypes.SELECT_GATEWAY_REQUEST]: takeLatest(actionTypes.SELECT_GATEWAY_REQUEST, selectGatewayFlow) }) .next() .isDone(); // expect(gatawayFlow().next().value).toEqual(all([ // takeEvery(actionTypes.GET_GATEWAYS_REQUEST, getGatewaysFlow), // takeEvery(actionTypes.SELECT_GATEWAY_REQUEST, selectGatewayFlow), // ])); ---> THIS TEST WORKS CORRECT }); });Y mi prueba no pasó. Tengo este error en mi terminal. ¿Alguna idea de cómo puedo solucionarlo?
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(); }); });resultado de la prueba:
