+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
