+Testing obsolescence markers push: Cases A.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 A: simple cases
+Testcase 4: Push in the middle of the obsolescence chain
+
+A.4 Push in the middle of the obsolescence chain
+================================================
+
+.. (Where we show that we should not push the marker without the successors)
+..
+.. {{{
+..   B ◔
+..     |
+..   A⇠ø⇠○ A'
+..     |/
+..     ● O
+.. }}}
+..
+.. Markers exist from:
+..
+..  * `A ø⇠○ A'`
+..  * chain from A
+..
+.. Command runs:
+..
+..  * hg push -r B
+..
+.. Expected exchange:
+..
+..  * Chain from A
+..
+.. Expected Exclude:
