pytest帮你写出更好的程序

1、An example of a simple test:(一个简单的例子),命名为test_pytest1.py

def funx(x):

return x + 1

def test_answer():

assert funx(2) == 5

运行:

进入Python脚本路径:pytest test_pytest1.py

root@localhost:/home/ranxf/Python3单元测试/demo# pytest test_pytest1.py

============================= test session starts ==============================

platform linux — Python 3.5.2, pytest-3.2.3, py-1.4.34, pluggy-0.4.0

rootdir: /home/ranxf/Python3单元测试/demo, inifile:

collected 1 item

test_pytest1.py F

=================================== FAILURES ===================================

_____ test_answer ________

def test_answer():

assert funx(2) == 5

E assert 3 == 5

E + where 3 = funx(2)

test_pytest1.py:8: AssertionError

=========================== 1 failed in 0.02 seconds ===========================

进入python脚本路径:pytest -q test_pytest1.py(加一个参数-q),运行结果:

root@localhost:/home/ranxf/Python3单元测试/demo# pytest -q test_pytest1.py

F

=================================== FAILURES ===================================

_____ test_answer ________

def test_answer():

assert funx(2) == 5

E assert 3 == 5

E + where 3 = funx(2)

test_pytest1.py:8: AssertionError

1 failed in 0.02 seconds

两种运行结果有一点差异,就是少了一些版本信息。

3、一个测试类中创建多个测试用例:

一个测试类种创建多个测试用例

class TestClass:

def test_one(self):

x = “this”

assert “s” in x

def test_two(self):

x = “hello”

assert x == “hi”

4、pytest同样可以提供main()函数来执行测试用例:

目录结构:

“””

pytest中同样提供了main() 来函数来执行测试用例。pytest/

├── test_pytest1.py

├── test_pytest2.py

└── test_main.py

“””

注:主函数中的文件名只能是test_main.py(如果改为test_pytest3这种格式,将不会遍历执行同路径的其他用例)

import pytest

def test_main():

assert 5 != 5

if name == “main“:

pytest.main() # 遍历相同目录下的所以test开头的用例

pytest.main(“-q test_main.py”) # 指定测试文件

pytest.main(“/root/Documents/python3_1000/1000/python3_pytest”) # 指定测试目录

5、pytest生成Html格式的测试报告:

python3 -m pytest test_main.py –html=report/test_main.html
