# Tests for skip_broken and allowerasing
# (and a bit of nobest because the test case is too good to pass up)
#
# There are a lot of fairly complex, corner cases we test here especially towards the end.
#
# The test repo is generated from the "skip-broken" repo in this repository:
# https://github.com/relrod/ansible-ci-contrived-yum-repos
#
# It is laid out like this:
#
# There are three packages, `broken-a`, `broken-b`, `broken-c`.
#
# * broken-a has three versions: 1.2.3, 1.2.3.4, 1.2.4, 2.0.0.
# * 1.2.3 and 1.2.4 have no dependencies
# * 1.2.3.4 and 2.0.0 both depend on a non-existent package (to break depsolving)
#
# * broken-b depends on broken-a-1.2.3
# * broken-c depends on broken-a-1.2.4
# * broken-d depends on broken-a (no version constraint)
#
# This allows us to test various upgrades, downgrades, and installs with broken dependencies.
# skip_broken should usually be successful in the upgrade/downgrade case, it will just do nothing.
#
# There is a nobest testcase or two thrown in, simply because this organization provides a very
# good test case for that behavior as well. For example, just installing "broken-a" with no version
# will try to install 2.0.0 which is broken. With nobest=true, it will fall back to 1.2.4. Similar
# for upgrading.
