xargs:通过“查找” tests.py到manage.py测试

[英]xargs: passing 'find' tests.py to manage.py test

我尝试在Django项目目录中执行以下bash命令。 我正在使用django-nose作为TestRunner。

find . -name \tests.py -print0 | xargs -0 -Ixxx ./manage.py test xxx --settings=project_name.conf.test.settings

但出现以下错误(取决于tests.py文件的数量):

OSError: No such file /Users/user/Projects/project_name/{}

相同的-print0在第一次tests.py停止

完全回溯(命令whithout -print0

nosetests --verbosity 1 ./project_name/backend/tests.py
./project_name/contrib/auth/tests.py
./project_name/frontend/tests.py
 --failed --stop --nocapture --debug=DEBUG --nologcapture

在这种情况下使用xargs的正确方法是什么?

以下命令是正确的:

find . -name \tests.py -print0 | xargs -0 -Ixxx ./manage.py test xxx --settings=project_name.conf.test.settings

在运行它之前,我刚刚做了rm .noseids 如果使用错误的参数执行./manage.py test ,总是会引起问题。 然后将其写入.noseids并在之后每次执行。
