How do you mock only one export of a module and keep the rest real?

vi.mock("./utils", async (importOriginal) => ({
  ...(await importOriginal()),
  now: () => 0,
}));

• ✓Correct answer: As shown: spread the original module and override one export (in Jest: jest.requireActual)
• 2Impossible - a module is mocked entirely
• 3Use vi.spyOn("./utils", "now")
