+ 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.
