 | |
|     =====================================================================
 | |
| 
 | |
| ..
 | |
|     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::
 | |
| 
 | |
| py.test は、Python の `unittest スタイル`_ のテストに制限付きで対応しています。テストファイル内の ``unittest.TestCase`` のサブクラスとその ``test`` メソッドを自動的に探します。 ``setUp/tearDown`` メソッドを実行しますが、IO キャプチャのようなテストの扱いは pytest の標準的な方法で行います::
 | |
| 
 | |
|     # test_unittest.py の内容
 | |
| 
 | |
|     import unittest
 | |
|     class MyTest(unittest.TestCase):
 | |
|         def setUp(self):
 | |
|             print ("hello") # 出力内容をキャプチャ
 | |
|         def test_method(self):
 | |
|             x = 1
 | |
|             self.assertEquals(x, 3)
 | |
| 
 | |
| ..
 | |
|     Running it yields::
 | |
| 
 | |
| このコードを実行すると次のようになります::

|     $ py.test test_unittest.py
