Question

我正在尝试调试我的测试，而我正在使用自定义testrunner。当我没有将它与manage.py一起使用时，我能够让pdb正常运行。

在mysite / blog / tests / models_tests.py中我有以下几行：

import pdb; pdb.set_trace()

症状是当我运行“fab t：i = 1”时，测试开始运行。据推测set_trace正在进入，我只是看不到输出，因为光标只是闪烁然后在大约10秒后停止闪烁。如果我输入exit，我会收到以下错误：

Traceback (most recent call last):
  File "/home/jdp/Documents/www/env/local/lib/python2.7/site-packages/nose/loader.py", line 413, in loadTestsFromName
    addr.filename, addr.module)
  File "/home/jdp/Documents/www/env/local/lib/python2.7/site-packages/nose/importer.py", line 47, in importFromPath
    return self.importFromDir(dir_path, fqname)
  File "/home/jdp/Documents/www/env/local/lib/python2.7/site-packages/nose/importer.py", line 94, in importFromDir
    mod = load_module(part_fqname, fh, filename, desc)
  File "/home/jdp/Documents/www/mysite/blog/tests/models_tests.py", line 2, in <module>
    from blog.tests.factories import BlogFactory, CommentFactory
  File "/home/jdp/Documents/www/mysite/blog/tests/models_tests.py", line 2, in <module>
    from blog.tests.factories import BlogFactory, CommentFactory
  File "/usr/lib/python2.7/bdb.py", line 48, in trace_dispatch
    return self.dispatch_line(frame)
  File "/usr/lib/python2.7/bdb.py", line 67, in dispatch_line
    if self.quitting: raise BdbQuit
BdbQuit

我猜这意味着pdb正在加载，我只是看不到输出。此外，如果我输入“c”pdb知道继续，测试将继续进行。我只是看不到（pdb）提示符。这是否意味着“-s”无法正常工作？

在mysite / blog / tests / models_tests.py中我有以下几行：

import pdb; pdb.set_trace()

位于mysite / mysite / testrunner.py：

from django_coverage.coverage_runner import CoverageRunner
from django_nose import NoseTestSuiteRunner

class NoseCoverageTestRunner(CoverageRunner, NoseTestSuiteRunner):
    pass

位于mysite / mysite / settings.py：

EXTERNAL_APPS = [
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'south',
    'whoosh',
    'haystack',
    'django.contrib.markup',
    'django.contrib.gis',
    'world',
    # Uncomment the next line to enable the admin:
    'django.contrib.admin',
    # Uncomment the next line to enable admin documentation:
    # 'django.contrib.admindocs',
]

INTERNAL_APPS = [
    'blog',
]

INSTALLED_APPS = EXTERNAL_APPS + INTERNAL_APPS

位于mysite / mysite / test_settings.py：

# flake8: noqa
"""Settings to be used for running tests."""
import os

from mysite.settings import *


INSTALLED_APPS.append('django_nose')
INSTALLED_APPS.append('django_jasmine')

DATABASES = {
    'default': {
        'ENGINE': 'django.contrib.gis.db.backends.postgis',
        'NAME': 'website_db',                     
        'USER': 'xxx',
        'PASSWORD': 'xxx',
        'HOST': '',                      
        'PORT': '',                    
    }
}


EMAIL_BACKEND = 'django.core.mail.backends.locmem.EmailBackend'
SOUTH_TESTS_MIGRATE = False

TEST_RUNNER = 'mysite.testrunner.NoseCoverageTestRunner'
COVERAGE_MODULE_EXCLUDES = [
    'tests$', 'settings$', 'urls$', 'locale$',
    'migrations', 'fixtures', 'admin$', 'django_extensions',
]
COVERAGE_MODULE_EXCLUDES += EXTERNAL_APPS
COVERAGE_REPORT_HTML_OUTPUT_DIR = os.path.join(__file__, '../../coverage')

MEDIA_ROOT = os.path.join(__file__, '../../test_files/media')

最后，我在fabric中运行这些测试，位于mysite / fabfile.py：

from fabric.api import local, lcd, settings

def t(i=0):
    """
    Your central command for running tests. Call it like so:

        fab t
        fab t:i=0
    """
    command = 'python manage.py test -v 2 -s --settings=mysite.test_settings'
    if int(i) == 0:
        command += " --exclude='integration_tests' --exclude='jasmine_tests'"
    with settings(warn_only=True):
        result = local(command, capture=True)
        if result.failed:
            print result.stderr
            with lcd('test_files/media'):
                local('rm -rf image')
                print "Removed Test Folder Regardless of Failure"
        else:       
            with lcd('test_files/media'):
                local('rm -rf image')
                print "Tests OK. Deleting Images Folder"

Answer 1

好的，我发现了问题。

这article让我失望（在“以编程方式运行鼻子”一节下）。

显然当你以编程方式运行鼻子时，就像我使用fabric一样，nose会捕获sys.stdout，因此print语句将无效（显然pdb用于输出到控制台）。

当我在没有结构的命令提示符下输入此命令时，它会立即弹出（pdb）提示符：

./manage.py test -s --settings=mysite.test_settings

如果有人为这个问题找到解决方法，我宁愿能够只运行结构，但至少我可以在此期间继续取得进展。

即使在使用Django Nose的-s选项后，pdb仍然不会显示输出
