org.apache.jackrabbit.oak.spi.state.NodeStoreBranch.merge()
Merges the changes in this branch to the main content tree. Merging is done by rebasing the changes in this branch on top of the current head revision followed by a fast forward merge. @param hook the commit hook to apply while merging changes @param info commit info associated with this merge operation,or {@code null} if no local commit information is available @return the node state resulting from the merge. @throws CommitFailedException if the merge failed @throws IllegalStateException if the branch is already merged

        // Assert changes are not yet present in the trunk
        testState = store.getRoot().getChildNode("test");
        assertFalse(testState.getChildNode("newNode").exists());
        assertTrue(testState.getChildNode("x").exists());


        branch.merge(EmptyHook.INSTANCE);
