Question

我正在尝试将django测试分发到多个进程以加快测试运行。

我在虚拟环境中使用py.test。

我的相关版本是：

$ pip freeze | grep test
django-pytest==0.2.0
django-webtest==1.7.7
pytest==2.5.2
pytest-cov==1.6
pytest-django==2.6.2
pytest-xdist==1.10
scripttest==1.3

当我尝试命令时：

$ py.test -n 4

我收到错误：

usage: py.test [options] [file_or_dir] [file_or_dir] [...]
py.test: error: unrecognized arguments: -n

py.test traceconfig命令显示：

$ py.test --traceconfig

插件：cov，django

我注意到xdist插件旁边有一个-1。这是否表示该插件出错？

py.test --help没有列出xdist参数

Answer 1

想出来的是：

-p no:xdist

在tox.ini的addopts部分中。删除它，xdist工作。

py.test -n <number of =“”processes =“”> =＆gt; ＆＃34; py.test：错误：无法识别的参数：-n＆＃34; </number>
