Question

用鼻子测试烧瓶应用程序。我正在尝试使用with_setup装饰器来进行测试DRY，而不必重复设置每个测试功能。但它似乎没有运行@with_setup阶段。作为文档state我将它与测试函数一起使用而不是测试类。一些代码：

from flask import *
from app import app
from nose.tools import eq_, assert_true
from nose import with_setup


testapp = app.test_client()

def setup():
  app.config['TESTING'] = True
  RUNNING_LOCAL = True
  RUN_FOLDER = os.path.dirname(os.path.realpath(__file__))
  fixture = {'html_hash':'aaaa'} #mocking the hash

def teardown():
  app.config['TESTING'] = False
  RUNNING_LOCAL = False

@with_setup(setup, teardown)
def test_scrape_wellformed_html():

  #RUN_FOLDER = os.path.dirname(os.path.realpath(__file__))  #if it is here instead of inside @with_setup the code works..
  #fixture = {'html_hash':'aaaa'} #mocking the hash #if it is here the code works
  fixture['gush_id'] = 'current.fixed'
  data = scrape_gush(fixture, RUN_FOLDER)
  various assertions

例如，如果我在@with_setup块中创建fixture dict，而不是在特定的测试方法内（并且在每个人中），我将得到一个NameError（或类似的东西）

我想我错过了什么，只是不确定是什么。谢谢你的帮助！

问题是名称RUN_FOLDER和fixture作用于setup函数，因此test_scrape_wellformed_html无效。如果你看一下the code for with_setup，你会发现它没有做任何改变运行功能环境的事情。

为了做你想做的事，你需要让你的灯具全局变量：

testapp = app.test_client()
RUN_FOLDER = os.path.dirname(os.path.realpath(__file__))
fixture = None

def setup():
  global fixture

  app.config['TESTING'] = True
  fixture = {'html_hash':'aaaa'} #mocking the hash

def teardown():
  global fixture
  app.config['TESTING'] = False
  fixture = None

@with_setup(setup, teardown)
def test_scrape_wellformed_html():
    # run test here

nose @with_setup设置无法在测试中使用
