 ### API Tests (`test/bdd/api`)
 
 These tests are meant to test the different API endpoints and their parameters.
-They require a preimported test database, which consists of the import of a
-planet extract. A precompiled PBF with the necessary data can be downloaded from
-https://www.nominatim.org/data/test/nominatim-api-testdata.pbf
+They require a to import several datasets into a test database. You need at
+least 2GB RAM and 10GB discspace.
 
-The polygons defining the extract can be found in the test/testdb
-directory. There is also a reduced set of wikipedia data for this extract,
-which you need to import as well. For Tiger tests the data of South Dakota
-is required. Get the Tiger files `46*`.
 
-The official test dataset is derived from the 160725 planet. Newer
-planets are likely to work as well but you may see isolated test
-failures where the data has changed. To recreate the input data
-for the test database run:
+1. Fetch the OSM planet extract (200MB). See end of document how it got created.

+How the test database extract was generated
+-------------------------------------------
+The official test dataset was derived from the 180924 planet (note: such
+file no longer exists at https://planet.openstreetmap.org/planet/2018/).
+Newer planets are likely to work as well but you may see isolated test
