* Porting: substitute nose with ytest This huge commit substitutes nose with pytest as a testing system. Things done here: * deleted external/nose as it is no longer used * moved mock resources in their own directory 'test/mock/' * ported two tests (cmd/find, build_system) to pytest native syntax as an example * build_environment, log: used monkeypatch instead of try/catch * moved global mocking of fetch_cache to an auto-used fixture * moved global mocking from test/__init__.py to conftest.py * made `spack test` a wrapper around pytest * run-unit-tests: avoid running python 2.6 tests under coverage to speed them up * use `pytest --cov` instead of coverage run to cut down testing time * mock/packages_test: moved mock yaml configuration to files instead of leaving it in the code as string literals * concretize.py: ported tests to native pytest, reverted multiprocessing in pytest.ini as it was creating the wrong report for coveralls * conftest.py, fixtures: added docstrings * concretize_preferences.py: uses fixtures instead of subclassing MockPackagesTest * directory_layout.py: uses fixtures instead of subclassing MockPackagesTest * install.py: uses fixtures instead of subclassing MockPackagesTest * optional_deps.py: uses fixtures instead of subclassing MockPackagesTest optional_deps.py: uses fixtures instead of subclassing MockPackagesTest * packages.py: uses fixtures instead of subclassing MockPackagesTest * provider_index.py: uses fixtures instead of subclassing MockPackagesTest * spec_yaml.py: uses fixtures instead of subclassing MockPackagesTest * multimethod.py: uses fixtures instead of subclassing MockPackagesTest * install.py: now uses mock_archive_url * git_fetch.py: uses fixtures instead of subclassing MockPackagesTest * hg_fetch.py: uses fixtures instead of subclassing MockPackagesTest * svn_fetch.py, mirror.py: uses fixtures instead of subclassing MockPackagesTest repo.py: deleted * test_compiler_cmd.py: uses fixtures instead of subclassing MockPackagesTest * cmd/module.py, cmd/uninstall.py: uses fixtures instead of subclassing MockDatabase * database.py: uses fixtures instead of subclassing MockDatabase, removed mock/database * pytest: uncluttering fixture implementations * database: changing the scope to 'module' * config.py: uses fixtures instead of subclassing MockPackagesTest * spec_dag.py, spec_semantics.py: uses fixtures instead of subclassing MockPackagesTest * stage.py: uses fixtures instead of subclassing MockPackagesTest. Removed mock directory * pytest: added docstrings to all the fixtures * pytest: final cleanup * build_system_guess.py: fixed naming and docstrings as suggested by @scheibelp * spec_syntax.py: added expected failure on parsing multiple specs closes #1976 * Add pytest and pytest-cov to Spack externals. * Make `spack flake8` ignore externals. * run-unit-tests runs spack test and not pytest. * Remove all the special stuff for `spack test` - Remove `conftest.py` magic and all the special case stuff in `bin/spack` - Spack commands can optionally take unknown arguments, if they want to handle them. - `spack test` is now a command like the others. - `spack test` now just delegates its arguments to `pytest`, but it does it by receiving unknown arguments and NOT taking an explicit help argument. * Fix error in fixtures. * Improve `spack test` command a bit. - Now supports an approximation of the old simple interface - Also supports full pytest options if you want them. * Use external coverage instead of pytest-cov * Make coverage use parallel-mode. * change __init__.py docs to include pytest
