用 Python 玩测试

Python 库这么多，测试库肯定也是丰富无比。官网给出了Python测试框架的列表 PythonTestingToolsTaxonomy ，
常见的比如 unittest nose mock Selenium 等。本文简单了解一下 Python 的测试~
单元测试 unittest
首先，给出， unittest 文档地址 https://docs.python.org/4.5/library/unittest.html， 具体用法，就不翻译了，查查文档就行。
第一句话就乐了， unittest 是借鉴 Junit 实现的。
The unittest unit testing framework was originally inspired by JUnit and has a similar flavor as major unit testing frameworks in other languages.
unittest 支持以下四种方式：
- test fixture
- test case
- test suite
- test runner
首先是要写好TestCase，然后由TestLoader加载TestCase到TestSuite，然后由TextTestRunner来运行TestSuite，运行的结果保存在TextTestResult中，整个过程集成在unittest.main模块中。
unittest Demo
import unittest
class TestStringMethods(unittest.TestCase):
def test_upper(self):
self.assertEqual('foo'.upper(), 'FOO')
def test_isupper(self):
self.assertTrue('FOO'.isupper())
self.assertFalse('Foo'.isupper())
def test_split(self):
s = 'hello world'
self.assertEqual(s.split(), ['hello', 'world'])
# check that s.split fails when the separator is not a string
with self.assertRaises(TypeError):
s.split(2)
@unittest.skip("demonstrating skipping")
def test_nothing(self):
self.fail("shouldn't happen")
@unittest.skipIf(mylib.__version__ < (1, 3),
"not supported in this library version")
def test_format(self):
# Tests that work for only a certain version of the library.
pass
@unittest.skipUnless(sys.platform.startswith("win"), "requires Windows")
def test_windows_support(self):
# windows specific testing code
pass
if __name__ == '__main__':
unittest.main()##参考文档
