+which the postgres provider can connect. The server will need to have postgis

+By default the test uses the following connection options:
+    dbname='qgis_test'
+    host=localhost
+    port=5432
+    user='postgres'
+    password='postgres'
+
+If this does not match your setup you can set the environment variable
+QGIS_PGTEST_DB to the desired connection string.

+creates some tables containing test data.
