.. _`unittest.TestCase`:
Support for unittest.TestCase
=====================================================================
py.test has limited support for running Python `unittest.py style`_ tests.
It will automatically collect ``unittest.TestCase`` subclasses
and their ``test`` methods in test files. It will invoke
``setUp/tearDown`` methods but also perform py.test's standard ways
of treating tests such as IO capturing::
# content of test_unittest.py
import unittest
class MyTest(unittest.TestCase):
def setUp(self):
print ("hello") # output is captured
def test_method(self):
x = 1
self.assertEquals(x, 3)
Running it yields::
$ py.test test_unittest.py
