Was ist die Methode, um in vue3 schreibgeschützt und reaktionsfähig zu implementieren?

it("happy path", () => {
    console.warn = vi.fn();
    const original = {
      foo: 1,
    };
    const observed = readonly({
      foo: 1,
    });
    expect(original).not.toBe(observed);
    expect(observed.foo).toBe(1);
    //  set不起作用
    observed.foo = 2; 
    expect(observed.foo).toBe(1);
    //  当被set的时候，发出一个警告
    expect(console.warn).toBeCalled();
  });
