+====================================
+Testing head checking code: Case B-1
+====================================
+
+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 B: simple case involving pruned changesets
+TestCase 1: single pruned changeset
+
+.. old-state:
+..
+.. * 1 changeset branch
+..
+.. new-state:
+..
+.. * old branch is pruned
+.. * 1 new unrelated branch
+..
+.. expected-result:
+..
+.. * push allowed
