+test_description='Using a symbolic ref as a branch name alias
+
+This test uses refs/heads/alias as a symbolic ref to refs/heads/master, and
+verifies that it works as a branch name alias, namely:
+ - commits on "master" are automatically reflected on "alias"
+ - creating or deleting "alias" does not affect "master"
+ - the "alias" is not broken by "git gc"
+'
+. ./test-lib.sh
