useFetch.test.js

it("should return data after fetch", async () => {
    // Mock API
    jest.spyOn(global, "fetch").mockImplementation(() =>
      Promise.resolve({
        json: () => Promise.resolve(stubbedCountries),
      })
    );

    // Execute
    const { result, waitForNextUpdate } = renderHook(() =>
      useFetch(stubbedFetchUrl, { current: true }, [])
    );
    await waitForNextUpdate();

    // Assert
    expect(result.current).toStrictEqual({
      loading: false,
      data: stubbedCountries,
      error: null,
    });
  });
