编写和运行测试。 ImportError：没有模块命名为generic

Question

我是tests in Django的新手。我需要写一对夫妇。

Django版本1.9.7。 OS：Linux version 4.2.0-42-generic (buildd@lgw01-54) (gcc version 5.2.1 20151010 (Ubuntu 5.2.1-22ubuntu2)) #49-Ubuntu SMP Tue Jun 28 21:26:26 UTC 2016

我简单的测试代码：

cat animal/tests.py 

from django.test import TestCase 
from animal.models import Animal 

class AnimalTestCase(TestCase): 
    def say_hello(self): 
     print('Hello, World!') 

我这样./manage.py test animal

执行它，会出现以下错误：

Traceback (most recent call last): 
    File "./manage.py", line 13, in <module> 
    execute_from_command_line(sys.argv) 
    File "/path-to-venv/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 353, in execute_from_command_line 
    utility.execute() 
    File "/path-to-venv/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 327, in execute 
    django.setup() 
    File "/path-to-venv/local/lib/python2.7/site-packages/django/__init__.py", line 18, in setup 
    apps.populate(settings.INSTALLED_APPS) 
    File "/path-to-venv/local/lib/python2.7/site-packages/django/apps/registry.py", line 85, in populate 
    app_config = AppConfig.create(entry) 
    File "/path-to-venv/local/lib/python2.7/site-packages/django/apps/config.py", line 90, in create 
    module = import_module(entry) 
    File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module 
    __import__(name) 
    File "/path-to-venv/local/lib/python2.7/site-packages/autofixture/__init__.py", line 5, in <module> 
    from autofixture.base import AutoFixture 
    File "/path-to-venv/local/lib/python2.7/site-packages/autofixture/base.py", line 7, in <module> 
    from django.contrib.contenttypes.generic import GenericRelation 
ImportError: No module named generic 

我在做什么错？

Answer 1

您安装的django-autofixture版本不支持Django 1.9，因为它已经过时导入GenericRelation。

尝试升级到最新版本。该项目的changelist表示在版本0.11.0中添加了Django 1.9支持。

为了Django的在你的AnimalTestCase运行你的方法，你需要重新命名它，使它开始test_：

class AnimalTestCase(TestCase): 
    def test_say_hello(self): 
     print('Hello, World!') 

Answer 2

你打错进口，正确的进口主要是来自

django.contrib.contenttypes.fields import GenericRelation 

但这似乎实际上来自django自动夹具，而不是从您自己的代码。好消息是，你不需要自动夹具进行这种简单的测试。只要说再见吧。
