py.test: error: unrecognized arguments
提问by Hello lad
I have a project directory looks like following
我有一个项目目录如下
Projects/
....this_project/
........this_project/
............__init__.py
............code.py
............tests/
................conftest.py
................test_1.py
................test_2.py
and I added a command line option (--PALLADIUM_CONFIG) by putting following codes into conftest.py
我通过将以下代码放入 conftest.py 添加了一个命令行选项（--PALLADIUM_CONFIG）
def pytest_addoption(parser):
parser.addoption("--PALLADIUM_CONFIG", action="store")
@pytest.fixture
def PALLADIUM_CONFIG(request):
return request.config.getoption("--PALLADIUM_CONFIG")
And what strange is:
奇怪的是：
if I cd into
如果我进入
Projects/this_project/this_project
or
或者
Projects/this_project/this_project/tests
and run
并运行
py.test --PALLADIUM_CONFIG=***
if runs well
如果运行良好
but if I locate myself in for example
但是如果我把自己定位在例如
Projects/this_project
or
或者
Projects
then pytest gives me error
然后pytest给我错误
py.test: error: unrecognized arguments: --PALLADIUM_CONFIG=***

That's a limitation of pytest itself. Take a look at the docs:
这是 pytest 本身的限制。看看文档：
Note that pytest does not find conftest.py files in deeper nested sub directories at tool startup. It is usually a good idea to keep your conftest.py file in the top level test or project root directory.
请注意，pytest 在工具启动时不会在更深的嵌套子目录中找到 conftest.py 文件。将 conftest.py 文件保存在顶级测试或项目根目录中通常是个好主意。
One solution is to create an external plugin, or move the option to a conftestfile nearer the root.
一种解决方案是创建一个外部插件，或将选项移动到conftest更靠近根目录的文件中。
