Example on how user roles work in TestCafe

user_role_example.js

import { Role } from "testcafe";

const user = Role("https://example.com/login", async t => {
  // Steps for logging in go here.
});

fixture("My application")
  .page("https://example.com/home")
  .beforeEach(async t => {
    await t.useRole(user);
  });

test("My first test", async t => {
  // Goes through the login process. After
  // successful authentication, it returns to
  // https://example.com/home to continue with
  // your test.
});

test("My second test", async t => {
  // Immediately authenticates you as the user
  // without going through the login process. It
  // should go to https://example.com/home to
  // continue with your test.
});
