pytest:帮助你编写更好的程序¶
pytest: helps you write better programs
The pytest
framework makes it easy to write small, readable tests, and can
scale to support complex functional testing for applications and libraries.
pytest
requires: Python 3.8+ or PyPy3.
PyPI package name: pytest
一个简单的例子¶
A quick example
# test_sample.py 的内容
def inc(x):
return x + 1
def test_answer():
assert inc(3) == 5
执行它:
$ pytest
=========================== test session starts ============================
platform linux -- Python 3.x.y, pytest-8.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 =============================
由于 pytest
的详细断言自省,因此仅使用简单的 assert
语句。
有关使用 pytest 的基本介绍,请参阅: 入门。

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