我正在尝试调试我的测试,并且正在使用自定义测试运行程序。当我不将它与 manage.py 结合使用时,我可以让 pdb 正常工作。
在 mysite/blog/tests/models_tests.py 我上面有以下几行:
import pdb; pdb.set_trace()
症状是当我运行“fab t:i=1”时,测试开始运行。大概 set_trace 正在启动,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。如果我键入 exit,我会收到以下错误:
Traceback (most recent call last):

BdbQuit
我猜这意味着 pdb 正在加载,我只是看不到输出。此外,如果我键入“c”,pdb 知道继续,并且测试通过。我只是看不到(pdb)提示。这是否意味着“-s”不能正常工作?

最后,我从位于 mysite/fabfile.py 的结构中运行这些测试:
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"
