鼻子没有找到 Django 测试

Question

我正在尝试在我当前的项目中使用 Django-nose，但我不知道如何让鼻子运行我的测试。于是我开始了一个简单的Django 1.4.1项目来了解nose。但即使是在这个简单的测试项目上，我也无法运行它。

在我继续之前：我知道 Stackoverflow 上有很多类似的问题，例如这个：

How do I tell Django-nose where my tests are?

但是在谷歌搜索、阅读博客文章和 StackOverflow 答案之后，我仍然无法运行它。

我如何设置我的测试项目

1. 创建虚拟环境。
2. pip install django django-nose nose。
3. 使用django-admin.py startproject djangonosetest 创建项目。
4. 创建应用程序manage.py startapp testapp

5. 编辑 settings.py：

   • 将ENGINE 设置为django.db.backends.sqlite3
   • 已将django_nose、testapp 添加到INSTALLED_APPS
   • 已添加TEST_RUNNER = 'django_nose.NoseTestSuiteRunner'。

6. 运行manage.py test

但我得到的只是这个输出：

nosetests --verbosity 1
Creating test database for alias 'default'...

----------------------------------------------------------------------
Ran 0 tests in 0.000s

OK
Destroying test database for alias 'default'...

但至少应该运行默认测试用例。

当我运行python manage.py test djangonosetest.testapp.tests:SimpleTest 时，它会运行测试。但是，如果我必须为我拥有的每个测试文件都这样做，那似乎有点矫枉过正。但它证明了测试是可以运行的。

当我运行manage.py test -v 3（高详细级别）时，出现了：

nose.selector: INFO: /Users/Jens/Projects/Django/djangonosetest/djangonosetest/settings.py is executable; skipped
nose.selector: INFO: /Users/Jens/Projects/Django/djangonosetest/djangonosetest/settings.pyc is executable; skipped

nose.selector: INFO: /Users/Jens/Projects/Django/djangonosetest/manage.py is executable; skipped

鼻子确实找到了我的tests.py，但由于某种原因跳过了它。

测试代码

测试代码是 Django 创建的默认 TestCase。

"""
This file demonstrates writing tests using the unit test module. These will pass
when you run "manage.py test".

Replace this with more appropriate tests for your application.
"""

from Django.test import TestCase


class SimpleTest(TestCase):
    def test_basic_addition(self):
        """
        Tests that 1 + 1 always equals 2.
        """
        self.assertEqual(1 + 1, 2)

那么我如何告诉 Django-nose/nose 我的测试在哪里？

更新

如果发现有关该主题的有趣的 Google 网上论坛帖子和 Stackoverflow 答案：

• Google Groups Post
• Stackoverflow answer

两者都归结为鼻子会跳过可执行文件的事实。这就是为什么我得到tests.py is executable; skipped。问题是文件不可执行：

----------+ 1 Jens  staff  383 13 Okt 00:01 tests.py

我也尝试过使用 u-x、g-x 和 o-x，但无论如何都跳过了鼻子。我觉得这是一个错误。该文件在鼻子中找到，不可执行但仍被跳过。

一种解决方法是使用 --exe 开关。运行 manage.py test --exe 运行测试。虽然它比其他解决方法更好，但我对该解决方案并不完全满意。

Answer 1

我今天遇到了同样的问题，我已经解决了。

试试：

chmod a-x djangonosetest/djangonosetest/testapp/*.py

Answer 2

我认为可能是在 Django 1.4 中，如果您不指定项目根目录，则需要在已安装的应用程序中指定项目。不要只是'testapp'，试试'djangonosetest.testapp'

https://docs.djangoproject.com/en/dev/ref/settings/#std:setting-INSTALLED_APPS 看看他们的例子。
