Answering my own question. Basically I'm making a shallow render of my component and verifying that if authenticated is rendering the redirect component otherwise the App one. Here the code:

function setup() {
  const enzymeWrapper = shallow();

  return {
    enzymeWrapper
  };
}

describe("AuthenticatedApp component", () => {
  it("renders Redirect when user NOT autheticated", () => {
    authApi.isUserAuthenticated = jest.fn(() => false);
    const { enzymeWrapper } = setup();

    expect(enzymeWrapper.find(Redirect)).toHaveLength(1);
  });

  it("renders AppWithData when user autheticated", () => {
    authApi.isUserAuthenticated = jest.fn(() => true);
    const { enzymeWrapper } = setup();

    expect(enzymeWrapper.find(AppWithData)).toHaveLength(1);
  });
});
