pytest: helps you write better programs

pytest 框架讓編寫小型且具可讀性的測試變得容易，並能擴展以支援應用程式與程式庫的複雜功能測試。

PyPI 軟體包名稱： pytest

A quick example

# content of test_sample.py
def inc(x):
    return x + 1


def test_answer():
    assert inc(3) == 5

To execute it:

$ pytest
=========================== test session starts ============================
platform linux -- Python 3.x.y, pytest-9.x.y, pluggy-1.x.y
rootdir: /home/sweet/project
collected 1 item

test_sample.py F                                                     [100%]

================================= FAILURES =================================
_______________________________ test_answer ________________________________

    def test_answer():
>       assert inc(3) == 5
E       assert 4 == 5
E        +  where 4 = inc(3)

test_sample.py:6: AssertionError
========================= short test summary info ==========================
FAILED test_sample.py::test_answer - assert 4 == 5
============================ 1 failed in 0.12s =============================

Due to pytest's detailed assertion introspection, only plain assert statements are used. See Get started for a basic introduction to using pytest.
