| 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. |
