which test the API interface using a BDD test framework and there are unit
tests for specific PHP functions.
-This test directory is sturctured as follows:
+This test directory is structured as follows:
```
-+- bdd Functional API tests
The tests can be configured with a set of environment variables (`behave -D key=val`):
- * `BUILDDIR` - build directory of Nominatim installation to test
* `TEMPLATE_DB` - name of template database used as a skeleton for
the test databases (db tests)
* `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
* `DB_PASS` - (optional) password for database login
* `SERVER_MODULE_PATH` - (optional) path on the Postgres server to Nominatim
- module shared library file
+ module shared library file (only needed for legacy tokenizer)
* `REMOVE_TEMPLATE` - if true, the template and API database will not be reused
during the next run. Reusing the base templates speeds
up tests considerably but might lead to outdated errors
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.
