用 Python 玩测试

Coding~ 6 阅读

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:

关系

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()
