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 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
 | 
						|
