| Tests for WFS-T provider using QGIS Server through qgis_wrapped_server.py. | ||
| This is an integration test for QGIS Desktop WFS-T provider and QGIS Server | ||
| WFS-T that check if QGIS can talk to and uderstand itself. | ||
| The test uses testdata/wfs_transactional/wfs_transactional.qgs and three | ||
| initially empty shapefiles layrs with points, lines and polygons. | ||
| All WFS-T calls are executed through the QGIS WFS data provider. | ||
| The three layers are | ||
| 1. populated with WFS-T | ||
| 2. checked for geometry and attributes | ||
| 3. modified with WFS-T | ||
| 4. checked for geometry and attributes | ||
| 5. emptied with WFS-T calls to delete | ||
