FAILED (errors=1)
Destroying test database for alias 'default'...

tests.py:

from django.test import TestCase
from django.core.urlresolvers import resolve
from lists.views import home_page

class HomePageTest(TestCase):
def test_root_url_resolves_to_home_page_view(self):
    found = resolve('/')
    self.assertEqual(found.func,home_page)

urls.py

from django.conf.urls import url,patterns,include
from django.contrib import admin
urlpatterns = ['',
url(r'^admin/', admin.site.urls),
url(r'^$', 'lau.views.home_page', name='home'),]

views.py

from django.shortcuts import render
def home_page():
pass

不管怎么修改都是ERROR: lau.tests (unittest.loader._FailedTest)
google了很久，只看到一个类似的
原答案：I have found my mistake. I started to use backspace for all the lines and clear all the irrelevant spaces in tests.py and the problem is solved now.
我真的费解死了，解决的让人摸不着头脑，祈求大神解答，谢谢，小白再次谢过。
