Jest: [BUG] Jest 16 istirahat menggunakan `toHaveBeenCalledWith` dengan 0 argumen untuk menguji fungsi yang telah dipanggil tanpa argumen

Apakah Anda ingin meminta _fitur_ atau melaporkan _bug_?

Laporkan bug

Apa perilaku saat ini?

Pada Jest 16: menguji toHaveBeenCalledWith dengan 0 argumen tidak lulus ketika mata-mata dipanggil dengan 0 argumen

Pada Jest 15: menguji toHaveBeenCalledWith dengan 0 argumen berlalu ketika mata-mata dipanggil dengan 0 argumen

Jika perilaku saat ini adalah bug, berikan langkah-langkah untuk mereproduksi dan jika mungkin repositori minimal di GitHub yang dapat kami npm install dan npm test .

Tes minimal:

it('can check that a function is called without arguments', () => {
    let fn = jasmine.createSpy();

    fn();
    expect(fn).toHaveBeenCalledWith();
});

Apa perilaku yang diharapkan?

Pengujian menggunakan toHaveBeenCalledWith dengan 0 argumen harus memberikan pernyataan ketika mata-mata dipanggil dengan 0 argumen

Jalankan Jest lagi dengan --debug dan berikan konfigurasi lengkap yang dicetaknya.
