+====================================
+Testing head checking code: Case D-2
+====================================
+
+Mercurial checks for the introduction of new heads on push. Evolution comes
+into play to detect if existing branches on the server are being replaced by
+some of the new one we push.
+
+This case is part of a series of tests checking this behavior.
+
+Category D: remote head is "obs-affected" locally, but result is not part of the push
+TestCase 1: remote branch has 2 changes, head is pruned, other is rewritten but result is not pushed
+
+.. old-state:
+..
+.. * 1 changeset branch
+..
+.. new-state:
+..
+.. * old head is pruned
+.. * 1 new branch succeeding to the other changeset in the old branch
+.. * 1 new unrelated branch
+..
+.. expected-result:
+..
+.. * push allowed
+.. * pushing only the unrelated branch: denied
