Soy nuevo en las pruebas de mi proyecto. Quiero probar la API de llamada. He estado probando la API de llamada pero no tengo idea de cómo probar la llamada POST .

 export default { get: () => { return Promise.resolve({ data: [{ "id": "qcCK3SzECmaZAGRrHjaC", "status": "refused", "pct": 20, "amount": 200, "email": "a@a", "name": "test2", "vat": "40", "fileName": "preview-facture-free-201801-pdf-1.jpg", "date": "2002-02-02", "commentAdmin": "pas la bonne facture", "commentary": "test2", "type": "Restaurants et bars", "fileUrl": "https://firebasestorage.googleapis.com/v0/b/billable-677b6.a…f-1.jpg?alt=media&token=4df6ed2c-12c8-42a2-b013-346c1346f732" }] }) }, }

en la carpeta tests :

 import firebase from "../__mocks__/firebase" import BillsUI from "../views/BillsUI.js" describe("Given I am connected as Employee",()=>{ describe("When I navigate to bills page",()=>{ test("fetches bills from mock API GET", async () => { const getSpy = jest.spyOn(firebase, "get") const bills = await firebase.get() expect(getSpy).toHaveBeenCalledTimes(1) expect(bills.data.length).toBe(1) }) test("fetches bills from an API and fails with 404 message error", async () => { firebase.get.mockImplementationOnce(() => Promise.reject(new Error("Erreur 404")) ) const html = BillsUI({ error: "Erreur 404" }) document.body.innerHTML = html const message = await screen.getByText(/Erreur 404/) expect(message).toBeTruthy() }) test("fetches messages from an API and fails with 500 message error", async () => { firebase.get.mockImplementationOnce(() => Promise.reject(new Error("Erreur 500")) ) const html = BillsUI({ error: "Erreur 500" }) document.body.innerHTML = html const message = await screen.getByText(/Erreur 500/) expect(message).toBeTruthy() }) }) })

¿Así es como Mocking API obtiene y prueba alguna idea de cómo simular una llamada API POST?
