Testing · Middle · Question 11 of 75

Why does this mock factory fail?

const user = { name: "Ann" };
vi.mock("./api", () => ({ getUser: () => user }));

✓Correct answer: The factory is hoisted above the const, so user isn't initialized yet; use vi.hoisted or define data inside the factory
2Factories can't return objects
3vi.mock needs an absolute path

Explanation

const user = vi.hoisted(() => ({ name: "Ann" })) is hoisted together with the mock. Jest allows only variables prefixed with mock.
