### 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.
See the [Development Setup chapter](Development-Environment.md#preparing-the-test-database)
for instructions on how to set up this database.
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
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
failures where the data has changed.
The official test dataset is saved in the file `test/testdb/apidb-test-data.pbf`
and compromises the following data:
The official test dataset can always be downloaded from
[nominatim.org](https://www.nominatim.org/data/test/nominatim-api-testdata.pbf)
To recreate the input data for the test database run:
* Geofabrik extract of Liechtenstein
* 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.
Note that most testing of the gazetteer output of osm2pgsql is done in the tests
of osm2pgsql itself. The BDD tests are just there to ensure compatibility of
the osm2pgsql and Nominatim code.
