pytest的hello world

pyt1.py

def func(x):

  print (x+1);

  return x+1;

def test_answer():

  assert func(3) == 5;

def test_2():

  assert func(4) == 5;

使用py.test 测试

py.test pyt.py

输出

=============================== test session starts ===============================
platform linux2 -- Python 2.7.3 -- py-1.4.20 -- pytest-2.5.2

collected 2 items

pyt1.py F.

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

___________________________________ test_answer ___________________________________

def test_answer():

> assert func(3) == 5;

E assert 4 == 5

E + where 4 = func(3)

pyt1.py:6: AssertionError

--------------------------------- Captured stdout ---------------------------------

@@@@@@@@@@@@@@@@@@@@@@

另一种执行方法：

pyt2.py

import pytest

pytest.main("-x ./pyt1.py");

执行

python py2.py

输出：

E assert 4 == 5

E + where 4 = func(3)

pyt1.py:6: AssertionError
