−Testing head checking code: Case B-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 B: simple case involving pruned changesets
+
−TestCase 2: multi-changeset branch, head is pruned, rest is superceeded, through other
