* `TEST_DB` - name of test database (db tests)
* `API_TEST_DB` - name of the database containing the API test data (api tests)
* `API_TEST_FILE` - OSM file to be imported into the API test database (api tests)
+ * `API_ENGINE` - webframe to use for running search queries, same values as
+ `nominatim serve --engine` parameter
* `DB_HOST` - (optional) hostname of database host
* `DB_PORT` - (optional) port of database on host
* `DB_USER` - (optional) username of database login
API tests should only be testing the functionality of the website PHP code.
Most tests should be formulated as BDD DB creation tests (see below) instead.
-#### Code Coverage
+#### Code Coverage (PHP engine only)
The API tests also support code coverage tests. You need to install
[PHP_CodeCoverage](https://github.com/sebastianbergmann/php-code-coverage).
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.
