| 129 |  Tests nextFromSimpleAxis(). More exactly that all the logic in | 
| 130 |  QAbstractXmlNodeModel::iterate() is as we expect to. Subsequently, a lot | 
| 131 |  of testing code is in LoadingModel(.cpp). | 
| 132 |  | 
| 133 |  Approach: | 
| 134 |  | 
| 135 |   1. In initTestCase() we loaded tree.xml into LoadingModel and | 
| 136 |      stored the root node in m_rootNode. | 
| 137 |   2. We execute a query that navigates from m_rootNode and write out | 
| 138 |      the result using QXmlFormatter. | 
| 139 |   3. We execute the exact same query, but this time use the built in node backend, | 
| 140 |      and write out the result in the same way. This is our baseline. | 
| 141 |   4. Compare the two. | 
| 142 |  | 
| 143 |   Hence we check QAbstractXmlNodeModel::iterate() and friends against our XQuery | 
| 144 |   code, which in turn is (mainly) checked by the XQTS. This means safer testing | 
| 145 |   since we don't create baselines manually, and it also means that we can modify | 
| 146 |   the input file, tree.xml, without having to update static baselines. |
