@adamjstewart: can you try this out and see if it allows you to test within your spack environment successfully? |

I made some changes based on @scheibelp's comments that simplify this quite a bit. |
Previously, `spack test` would fail within a new spack environment, because it could not import `pkg_resources` (part of `setuptools`) Parts of `pytest` use `setuptools`, but we do not need them for Spack, so it's an unnecessary dependency. - [x] Remove calls to parts of `pytest` that need setuptools

@scheibelp: I removed both functions -- I suppose that does make it much less likely someone will reintroduce this bug. |

Previously,
spack testwould fail within a new spack environment, because it could not importpkg_resources(part ofsetuptools) Parts ofpytestusesetuptools, but we do not need them for Spack, so it's an unnecessary dependency.Patching
pytestis nasty but it's a lot simpler than vendoring yet another mess of packages. Also, recent versions ofpytestdo not depend onsetuptools(see pytest-dev/pytest#5063). We're just stuck with an old version ofpytestbecause we still support Python 2.6.Astute readers may note that
jinja2also usespkg_resources, but we don't use any parts of it that actually importpkg_resources. So we do not need to remove these imports fromjinja2.pytestthat need setuptools
