Lo hice de esta manera para poder simplificar el código un poco mas :P

Reto completado :D

Si son de pifiarle a los nombres como yo, una buena practica es poner los string referentes a las acciones en un archivo de "types" src/types/actionsTypes.js

export const ADD_TO_CART = "'ADD_TO_CART'";
export const REMOVE_FROM_CART = 'REMOVE_FROM_CART';

luego en reducer, actions y test simplemente lo exportan

import { ADD_TO_CART, REMOVE_FROM_CART } from '../types/actionsTypes';

listo si algo sale mal o se modifica el nombre este string se encuentra definido en 1 solo lugar de esta manera evitamos errores y centralizamos las definiciones :D

es el mismo procedimiento para probar actions asíncronos por ejemplo usando redux thunk?

test('removefromcart Action', () =&gt; {
    const payload = ProductMock;
    const expected = {
      type: 'REMOVE_FROM_CART',
      payload,
    };
    expect(actions.removeFromCart(payload)).toEqual(expected);
  });```

Aquí mi solución:

test('removeFromCart Action', () => {
    const payload = ProductMock;
    const expected = {
      type: 'REMOVE_FROM_CART',
      payload,
    };
    expect(actions.removeFromCart(payload)).toEqual(expected);
  });

¿Cuál es la diferencia de utilizar test o it dentro del describe?

Luis Lira

¡Hola!

Tengo entendido que no hay ninguna diferencia, it es un alias de test según la documentación de Jest :D

Una forma de probar escenarios que son similares es con test.each. Quedaria algo asi:

describe('Actions', () => {
  const payload = ProductMock;

  const actionsToTest = [
    ['ADD_TO_CART', actions.addToCart, payload],
    ['REMOVE_FROM_CART', actions.removeFromCart, payload],
  ];

  test.each(actionsToTest)(
    'should call %p correctly',
    (actionType, actionToCall, expectedPayload) => {
      const expected = {
        type: actionType,
        payload: expectedPayload,
      };

      expect(actionToCall(payload)).toEqual(expected);
    }
  );
});

// actions.test.js import actions from '../../actions'; import ProductMock from '../../mocks/ProductMock';

describe('Actions', () => { test('addToCart Action', () => { const payload = ProductMock; const expected = { type: 'ADD_TO_CART', payload, }; expect(actions.addToCart(payload)).toEqual(expected); }); // reto agregar la elimacion del producto test('RemoveFromCart Action', () => { const payload = ProductMock; const expected = { type: 'REMOVE_FROM_CART', payload }; expect(actions.removeFromCart(payload)).toEqual(expected) }) });

Mi código para probar removeFromCart

test('removeFromCart action', () => {
    const payload = ProductMock;
    const expected = {
      type: 'REMOVE_FROM_CART',
      payload
    };
    expect(actions.removeFromCart(payload)).toEqual(expected);
  });
