+====================================
+Testing head checking code: Case D-7
+====================================
+
+Mercurial checks for the introduction of multiple heads on push. Evolution
+comes into play to detect if existing heads on the server are being replaced by
+some of the new heads we push.
+
+This test file 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 7: single changesets, superseeded multiple time then pruned (on a new changeset unpushed) changeset
+
+This is a partial push variation of B6
+
+.. old-state:
+..
+.. * 1 changeset branch
+..
+.. new-state:
+..
+.. * old branch is rewritten onto another one,
+.. * The rewriting it again rewritten on the root
+.. * the new version is then pruned.
+..
+.. expected-result:
+..
+.. * push allowed
