 ### API Tests (`test/bdd/api`)
 
 These tests are meant to test the different API endpoints and their parameters.

+They require to import several datasets into a test database. This is normally
+done automatically during setup of the test. The API test database is then
+kept around and reused in subsequent runs of behave. Use `behave -DREMOVE_TEMPLATE`
+to force a reimport of the database.
 
-The official test dataset was derived from the 180924 planet (note: such

-Newer planets are likely to work as well but you may see isolated test
-failures where the data has changed.

-The official test dataset can always be downloaded from

+ * extract of Autauga country, Alabama, US (for tests against Tiger data)
+ * additional data from `test/testdb/additional_api_test.data.osm`

 These tests check that data is imported correctly into the place table. They
 use the same template database as the DB Creation tests, so the same remarks apply.
