鼻子没有找到Django测试 [英] Nose doesn't find Django tests

查看：150
本文介绍了鼻子没有找到Django测试的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试在我目前的项目中使用Django-nose，但是我不知道如何让鼻子进行测试。所以我开始一个简单的Django 1.4.1项目来了解鼻子。但是，即使在这个简单的测试项目中，我也可以让它运行。



在我继续之前：我知道Stackoverflow有很多类似的问题，例如一个：



如何告诉Django鼻子我的测试是什么？



但在Googling之后，阅读博文和StackOverflow答案我还是可以



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. django-admin.py startproject djangonosetest 。

  4. 创建应用程序 manage.py startapp testapp

  5. 编辑settings.py：




    • 设置 ENGINE 到 django.db.backends.sqlite3

    • 添加 django_nose ， testap p 到 INSTALLED_APPS

    • 添加 TEST_RUNNER ='django_nose.NoseTestSuiteRunner' code>。


  6. 运行 manage.py test


但是我得到的都是这个输出：

  nosetests --verbosity 1 
创建别名default的测试数据库... 
 
 ------------- -------------------------------------------------- ------- 
 Ran 0测试在0.000s 
 
 OK 
销毁别名default的测试数据库...

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 它将运行测试。但是，如果我必须为每个测试文件执行此操作，这似乎有点过分。但是证明可以运行测试。



当我运行 manage.py test -v 3 （高详细级别）这显示：

  nose.selector：INFO：/ Users / Jens / Projects / Django / djangonosetest / djangonosetest / settings.py是可执行的;跳过
 nose.selector：INFO：/Users/Jens/Projects/Django/djangonosetest/djangonosetest/settings.pyc是可执行的;跳过

 nose.selector：INFO：/Users/Jens/Projects/Django/djangonosetest/manage.py是可执行的;跳过

鼻子肯定会找到我的tests.py，但是由于某种原因跳过它。 >

测试代码



测试代码是Django创建的默认TestCase。

 
此文件演示写入使用单元测试模块进行测试，当您运行manage.py test时，这些测试将通过
。 
 
将此替换为适用于您的应用程序的更合适的测试。 

 
从Django.test导入TestCase 
 
 
类SimpleTest（TestCase）：
 def test_basic_addition（self）：

测试1 + 1总是等于2. 

 self.assertEqual（1 + 1，2）

那么我如何告诉Django鼻子/鼻子我的测试是什么？



更新



如果发现一个有趣的Google网上论坛帖子和Stackoverflow的回答：





都归结为鼻子会跳过可执行文件，这就是为什么我得到 tests.py是可执行的;跳过。问题是文件不可执行：

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

我也尝试过ux，gx和ox，无论如何，鼻子跳过。我觉得这是一个bug。该文件位于鼻子中，不可执行但仍然被跳过。



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，但我并不完全满意这个解决方案。

解决方案

我今天有同样的问题，



尝试：

  chmod ax djangonosetest / djangonosetest / testapp /*.py


I am trying to use Django-nose in my current project, but I can't figure out how to get nose to run my tests. So I started a simple Django 1.4.1 project to get to know nose. But not even on this simple test project I could get it running.

Before I go on: I know there are a ton of similar questions on Stackoverflow, like for instance this one:

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

But after Googling around, reading blog posts and StackOverflow answers I still couldn't get it running.

How I set up my test project

  1. Create virtual environment.
  2. pip install django django-nose nose.
  3. Create project with django-admin.py startproject djangonosetest.
  4. Create an app manage.py startapp testapp

  5. Edit settings.py:

    • Set ENGINE to django.db.backends.sqlite3
    • Added django_nose, testapp to INSTALLED_APPS
    • Added TEST_RUNNER = 'django_nose.NoseTestSuiteRunner'.

  6. Run manage.py test

But all I got was this output:

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

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

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

But at least the default test case should have been run.

When I run python manage.py test djangonosetest.testapp.tests:SimpleTest it'll run the test. But that seems a bit overkill if I had to do it for every test file I have. But it proves that the tests can be run.

When I ran manage.py test -v 3 (high verbosity level) this showed up:

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/djangonosetest/urls.py is executable; skipped
nose.selector: INFO: /Users/Jens/Projects/Django/djangonosetest/djangonosetest/wsgi.py is executable; skipped
nose.selector: INFO: /Users/Jens/Projects/Django/djangonosetest/djangonosetest/testapp/models.py is executable; skipped
nose.selector: INFO: /Users/Jens/Projects/Django/djangonosetest/djangonosetest/testapp/models.pyc is executable; skipped
nose.selector: INFO: /Users/Jens/Projects/Django/djangonosetest/djangonosetest/testapp/views.py is executable; skipped
nose.selector: INFO: /Users/Jens/Projects/Django/djangonosetest/djangonosetest/testapp/tests.py is executable; skipped
nose.selector: INFO: /Users/Jens/Projects/Django/djangonosetest/djangonosetest/testapp/tests.pyc is executable; skipped
nose.selector: INFO: /Users/Jens/Projects/Django/djangonosetest/manage.py is executable; skipped

The nose does definitely find my tests.py but is skipping it for some reason.

The test code

The test code is the default TestCase Django creates.

"""
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)

So how do I tell Django-nose/nose where my tests are?

UPDATE

If found an interesting Google Groups post and Stackoverflow answer on the subject:

Both boil down to the fact that nose will skip executable files. That's why I get tests.py is executable; skipped. Problem is that the file is not executable:

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

I also tried it with u-x, g-x and o-x but nose skipped anyway. I get the feeling that this is a bug. The file is found in the nose, is not executable but still skipped.

A workaround is to use the --exe switch. Running manage.py test --exe runs the test. While it's better than the other workarounds I am not completely happy with that solution.

解决方案

I had the same issue today and I fixed it.

Try:

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