+Testing obsolescence markers push: Cases A.3
+============================================
+
+Mercurial pushes obsolescences markers relevant to the "pushed-set", the set of
+all changesets that requested to be "in sync" after the push (even if they are
+already on both side).
+
+This test belongs to a series of tests checking such set is properly computed
+and applied. This does not tests "obsmarkers" discovery capabilities.
+
+Category A: simple cases
+TestCase 3: old branch split in two, only one of the new one pushed
+Variants:
+# a: changesets are known on remote
+# b: changesets are known on remote (push needs -f)
+
+A.3 new branchs created, one pushed.
+====================================

+Testing obsolescence markers push: Cases C.2
+============================================
+
+Mercurial pushes obsolescences markers relevant to the "pushed-set", the set of
+all changesets that requested to be "in sync" after the push (even if they are
+already on both side).
+
+This test belongs to a series of tests checking such set is properly computed
+and applied. This does not tests "obsmarkers" discovery capabilities.
