在学习《Python Web开发：测试驱动方法》时遇到3.3.django单元测试部分的问题，测试root_url使用resolve('/')导致404错误。错误源于对resolve函数理解不准确，实际应检查'/home_page/'路径对应视图。修正后，测试通过。

python Web开发：测试驱动方法---3.3.django中的单元测试，3.4MVC、URL和视图函数：

tests.py测试类中写的第一个单元测试函数，如下：
class HomePageTest(TestCase):
    def test_root_url_resolves_to_home_page_view(self):
        #print "befor exct found"
        found = resolve('/')
        #print "befor exct found:",found
        self.assertEqual(found.func, home_page)

执行后报404错误

Traceback (most recent call last):
File "E:\djangoPreject\HelloWorld\cmdb\tests.py", line 11, in test_root_url_resolves_to_home_page_view
found = resolve('/')
File "C:\Python27\lib\site-packages\django\urls\base.py", line 27, in resolve
return get_resolver(urlconf).resolve(path)
File "C:\Python27\lib\site-packages\django\urls\resolvers.py", line 394, in resolve
raise Resolver404({'tried': tried, 'path': new_path})
Resolver404: {u'path': u'', u'tried': [[<RegexURLPattern None ^home_page/>]]}
