Ale*_*kov 5 python testing plone
我通过paster添加了几个BrowserViews,现在我正在尝试从plone.app.testing运行它们,因为我喜欢可重复且一致的测试.从浏览器手动调用视图可以正常工作.
我已尝试手动导入和初始化视图,以及从受限制的遍历调用该类.在这两种情况下,对象初始化都很好但是当我尝试触发渲染要么将实例作为函数调用,要么使用__call __()方法时,我得到以下错误:
*** KeyError: 'global_cache_settings
我在plone.app.test中查看README.rst中的示例,它似乎没有提到问题,快速谷歌搜索也没有产生任何结果.它可能是网站定制之一,但是在greping源代码时,我发现Products.CMFPlone中提到了'global_cache_settings',所以它可能是一个简单的东西:
eggs/Products.CMFPlone-4.1.4-py2.6.egg/Products/CMFPlone/skins/plone_templates/main_template.pt
28: <metal:cache use-macro="context/global_cache_settings/macros/cacheheaders">
29: Get the global cache headers located in global_cache_settings.
eggs/plone.app.layout-2.1.13-py2.6.egg/plone/app/layout/presentation/presentation.pt
11: <metal:cache use-macro="here/global_cache_settings/macros/cacheheaders">
12: Get the global cache headers located in global_cache_settings.
eggs/plonetheme.sunburst-1.1.6-py2.6.egg/plonetheme/sunburst/skins/sunburst_templates/main_template.pt
20: <metal:cache use-macro="context/global_cache_settings/macros/cacheheaders">
21: Get the global cache headers located in global_cache_settings.
这是相关的类声明:

测试文件:
import unittest2 as unittest
from . import PROD_INTEGRATION_TESTING
from plone.app.testing import setRoles, TEST_USER_ID
from Products.CMFCore.utils import getToolByName
from Products.MyProduct.browser.promoboardhome import PromoBoardHome
class TestPromoBoardHome(unittest.TestCase):
layer = PROD_INTEGRATION_TESTING
def setUp(self):
self.portal = self.layer['portal']
def test_call(self):
pbh = self.portal.restrictedTraverse('@@promoboardhome')
try:
pbh()
except KeyError:
print "that didn't work!"
import pdb; pdb.set_trace()
我在这里做错了吗？
浏览器视图只是命名的多适配器; 测试它们你已经在正确的上下文中调用它们并手动设置请求以提供为视图声明的接口; 在你的情况下可能是这样的:
from zope.interface import alsoProvides
from Products.MyProduct.browser.promoboardhome import IPromoBoardHome
class TestPromoBoardHome(unittest.TestCase):
layer = PROD_INTEGRATION_TESTING
def setUp(self):
self.portal = self.layer['portal']
self.request = self.layer['request']
alsoProvides(self.request, IPromoBoardHome)
我在像collective.nitf这样的包上有一堆浏览器视图测试.
快乐的测试!
