+Testing obsolescence markers push: Cases A.1
+============================================
+
+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 1: pushing a single head
+Subcases:
+# A.1.1 pushing a single head (2 variants)
+# A.1.2 pushing multiple changesets into a single head (2 variants)

+Testing obsolescence markers push: Cases C.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.

+============================================
+Testing obsolescence markers push: Cases D.4
+============================================
+
+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 D: Partial Information Case
+TestCase 4: Unknown changeset in between known changesets
