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::
