Tes gagal dengan xfail

Dalam latihan ini, Anda akan menggunakan penanda pytest untuk pertama kalinya guna menentukan perilaku pengujian. Anda sudah melihat fungsi multiple_of_two, yang memeriksa apakah num merupakan kelipatan 2 atau bukan. Pustaka pytest sudah diimpor untuk Anda.

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.
