+ Tests nextFromSimpleAxis(). More exactly that all the logic in
+ QAbstractXmlNodeModel::iterate() is as we expect to. Subsequently, a lot
+ of testing code is in LoadingModel(.cpp).
+
+ Approach:
+
+  1. In initTestCase() we loaded tree.xml into LoadingModel and
+     stored the root node in m_rootNode.
+  2. We execute a query that navigates from m_rootNode and write out
+     the result using QXmlFormatter.
+  3. We execute the exact same query, but this time use the built in node backend,
+     and write out the result in the same way. This is our baseline.
+  4. Compare the two.
+
+  Hence we check QAbstractXmlNodeModel::iterate() and friends against our XQuery
+  code, which in turn is (mainly) checked by the XQTS. This means safer testing
+  since we don't create baselines manually, and it also means that we can modify
+  the input file, tree.xml, without having to update static baselines.
