setup 使用，初始化数据 TODO

python unittest执行顺序问题字母的顺序执行

python mock handler

class MyUT(tornado.testing.AsyncHTTPTestCase):
  def get_app(self):
    settings = {
      "template_path": '../../../templates',
      "cookie_secret": 'secret',
      "login_url": '/admin/login',
      "debug": True
    }

    return Application([
      (r'/admin/create/super', handlers.CreateSuperUserHandler)
    ], **settings)


  def testGet(self):
    with mock.patch.object(handlers.CreateSuperUserHandler, 'get_current_user') as m:
      m.return_value = {}
      response = self.fetch('/admin/create/super')

    print(response.body)
    self.assertGreater(response.body.index('create'), 0)

mock handler更详细的例子 patch和patch.object 使用

Python

操作dict时避免出现KeyError的几种方法使用get方法更好
How to get name of exception that was caught in Python? 获取异常的的类名

try:
    foo = bar
except Exception as exception:
    assert type(exception).__name__ == 'NameError'
    assert exception.__class__.__name__ == 'NameError'

删除dict里面的元素 use del

>>> from collections import OrderedDict
>>> dct = OrderedDict()
>>> dct['a'] = 1
>>> dct['b'] = 2
>>> dct['c'] = 3
>>> dct
OrderedDict([('a', 1), ('b', 2), ('c', 3)])
>>> del dct['b']
>>> dct
OrderedDict([('a', 1), ('c', 3)])
>>>

python set 集合操做比如删除某个元素 set.remove(key)

subprocess returncode 什么时候为0

import subprocess as sp
child = sp.Popen(openRTSP + opts.split(), stdout=sp.PIPE)
streamdata = child.communicate()[0]
rc = child.returncode
