pytest.raises

Dalam latihan ini, Anda akan melanjutkan penulisan rangkaian uji pertama menggunakan pustaka pytest.

Fungsi multiple_of_two memeriksa apakah num merupakan kelipatan 2 atau bukan. Pada latihan ini, Anda akan membuat sebuah uji yang mengharapkan terjadinya Exception.

Petunjuk latihan

Definisikan context manager untuk uji pengecualian.
Tulis sebuah uji untuk memeriksa bahwa masukan nol multiple_of_two(num=0) menghasilkan pengecualian ValueError.

Latihan interaktif praktis

Cobalah latihan ini dengan menyelesaikan kode contoh berikut.

def multiple_of_two(num):
    if num == 0:
        raise(ValueError)
    return num % 2 == 0

def test_zero():    
  	# Add a context for an exception test here
    ____ ____(ValueError):
      	# Check zero input below
        multiple_of_two(____)

Learn what the basic testing types are and their features. Learn about test cases and how they help to implement tests. You will get more skilled with creating test functions and running pytest from CLI in IDE exercises. Finally, you will be able to differentiate the different testing types and create tests for each of them.
