Massimiliano Culpo 7dd3592eab Regression test for version selection with preferences (#25602) ... This commit adds a regression test for version selection with preferences in `packages.yaml`. Before PR 25585 we used negative weights in a minimization to select the optimal version. This may lead to situations where a dependency may make the version score of dependents "better" if it is preferred in packages.yaml.		2021-08-26 09:28:47 -07:00
