unittest.TestCase support
|
|
=====================================================================
|
|
|
|
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 like e.g. 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
