Chapter 50 — Testing Asoslari: Exercise 3 — Hard

Exercise 3 — Hard

Task:
Chapter 18'dagi kabi xatolik chiqaruvchi divide(a, b) function uchun (agar b === 0 bo'lsa xatolik chiqarsin), .toThrow() matcheri bilan test yozing. Bundan tashqari, jest.fn() yordamida oddiy "logger" mockini yaratib, divide funksiyasi muvaffaqiyatli natijani logger orqali "yozib qo'yishini" tekshiring.
Required Concepts:

• toThrow(), jest.fn()
  Hint:
  expect(() => divide(5, 0)).toThrow();
