Wrong documentation

[oleg-alexandrov]

I installed pytest and xdist. Latest version apparently:

py.test --version

This is pytest version 2.8.0,

Following http://pytest.org/latest/xdist.html?highlight=xdist I run:

py.test -n 4

py.test: error: unrecognized arguments: -n

Also for:

py.test -d

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

Hi,

I just installed it into a fresh pytest environment and everything seems to be working. How did you install it? What's the output when you run py.test? You should see installed plugins right in the header:

============================= test session starts =============================

I figured out the problem. pytest could not find xdist. It would have been nice to have some kind of informative error message. It is overall confusing that xdist is a separate package.

@oleg-alexandrov the documentation you referred to has nice big sections about first installing it links to its package and so on, i don't see how we can really improve on that

also having py.tests own code keep track of options of external plugins or 3rd party plugins add is counterproductive in various ways
