根据ini文件中的设置为金字塔Web应用程序编写doctest [英] Writing doctests for pyramid web app which depend on settings in ini file

问题描述

我想使用 webtest 模块为我的金字塔Web应用程序编写doctest.我这样尝试过:

I would like to write doctests for my pyramid web app, using the webtest module. I tried it like this:

from my_webapp import main
from webtest import TestApp

app = TestApp(main({}))
result = app.get('/')

这会在我的代码到达以下行时引发KeyError(因为some.url未知):

This raises a KeyError (because some.url is not known) when my code reaches this line:

url = request.registry.settings['some.url']

some.url的值在我的应用程序的粘贴ini文件中指定.运行测试代码时，有没有使用我的development.ini的简单方法?我尚未完全了解在金字塔启动期间如何/何时加载ini文件，因此很难在测试时确定将文件加载到何处.

The value of some.url is specified in the paster ini file of my application. Is there a simple way to use my development.ini when running my test code? I did not yet fully understand how/when the ini file is loaded during pyramid start up, so it's hard to figure out where to load it while testing.

推荐答案

main与ini文件的内容一起调用.从ini加载应用的一种简单方法是:

main is invoked with the contents of your ini file. A simple way to load your app from an ini is:

from pyramid.paster import get_app

app = get_app('testing.ini#main')
test_app = TestApp(app)

这希望"testing.ini"位于当前工作目录中，因此您可能需要对其进行调整.如果您希望它相对于树中的某个点，可以使用:

This expects "testing.ini" to be in the current working directory, so you may need to tweak that. If you'd like it to be relative to a spot in your tree you can use:

import os.path
import some_module

here = os.path.dirname(some_module.__file__)
app = get_app(os.path.join(here, 'testing.ini'))
