运行pylon webtests时出现ImportError和TestController未定义错误

Question

我有一个这样的文件夹结构：

gnukhata/tests/functional。

在这个functional文件夹里，我放了一些网页测试的文件。下面是一个测试的例子。

from gnukhata.tests import *

class TestVendorController(TestController):

def test_index(self):
    response = self.app.get(url(controller='vendor', action='index'))

运行这个测试文件后，出现了以下错误：

Traceback (most recent call last):
  File "/usr/lib/python2.6/dist-packages/twisted/trial/runner.py", line 651, in   loadByNames
    things.append(self.findByName(name))
  File "/usr/lib/python2.6/dist-packages/twisted/trial/runner.py", line 460, in findByName
    return filenameToModule(name)
  File "/usr/lib/python2.6/dist-packages/twisted/trial/runner.py", line 98, in filenameToModule
    return _importFromFile(fn)
  File "/usr/lib/python2.6/dist-packages/twisted/trial/runner.py", line 117, in _importFromFile
    module = imp.load_source(moduleName, fn, fd)
  File "test_vendor.py", line 1, in <module>
    from gnukhata.tests import *
exceptions.ImportError: No module named tests

如果我把gnukhata.tests改成gnukhata，系统就会显示以下错误：

   Traceback (most recent call last):
    File "/usr/lib/python2.6/dist-packages/twisted/trial/runner.py", line 651, in loadByNames
things.append(self.findByName(name))
    File "/usr/lib/python2.6/dist-packages/twisted/trial/runner.py", line 460, in findByName
return filenameToModule(name)
    File "/usr/lib/python2.6/dist-packages/twisted/trial/runner.py", line 98, in filenameToModule
return _importFromFile(fn)
    File "/usr/lib/python2.6/dist-packages/twisted/trial/runner.py", line 117, in _importFromFile
    module = imp.load_source(moduleName, fn, fd)
    File "test_vendor.py", line 3, in <module>
    class TestVendorController(TestController):
exceptions.NameError: name 'TestController' is not defined

Answer 1

在gnukhata/tests这个文件夹里有没有一个叫__init__.py的文件？如果没有的话，gnukhata.tests就不会被当作一个模块来识别，你就无法从里面导入东西。

如果这个文件确实存在的话，能不能把gnukhata/tests/__init__.py里面的导入语句发上来？

试试我最简单的配置，看看能不能用：

import logging

from pylons import request, response, session, tmpl_context as c, url
from pylons.controllers.util import abort, redirect

from gnukhata.lib.base import BaseController, render
from gnukhata import model
import gnukhata.model.meta as meta

在 init.py 文件里：

from unittest import TestCase

from paste.deploy import loadapp
from paste.script.appinstall import SetupCommand
from pylons import url
from routes.util import URLGenerator
from webtest import TestApp
from pylons import config

import pylons.test

__all__ = ['environ', 'url', 'TestController']

# Invoke websetup with the current config file
SetupCommand('setup-app').run([pylons.test.pylonsapp.config['__file__']])

environ = {}

class TestController(TestCase):

    def __init__(self, *args, **kwargs):
        wsgiapp = pylons.test.pylonsapp
        config = wsgiapp.config
        self.app = TestApp(wsgiapp)
        url._push_object(URLGenerator(config['routes.map'], environ))
        TestCase.__init__(self, *args, **kwargs)
