## Executing Tests
All tests are located in the `\test` directory.
All tests are located in the `/test` directory.
### Preparing the test database
Some of the behavioural test expect a test database to be present. You need at
least 2GB RAM and 10GB disk space to create the database.
First create a separate directory for the test DB and fetch the test planet
data and the Tiger data for South Dakota:
```
mkdir testdb
cd testdb
wget https://www.nominatim.org/data/test/nominatim-api-testdata.pbf
wget -O - https://nominatim.org/data/tiger2018-nominatim-preprocessed.tar.gz | tar xz --wildcards --no-anchored '46*'
```
Configure and build Nominatim in the usual way:
```
cmake $USERNAME/Nominatim
make
```
Create a minimal test settings file:
```
tee .env << EOF
NOMINATIM_DATABASE_DSN="pgsql:dbname=test_api_nominatim"
NOMINATIM_USE_US_TIGER_DATA=yes
NOMINATIM_TIGER_DATA_PATH=tiger
NOMINATIM_WIKIPEDIA_DATA_PATH=$USERNAME/Nominatim/test/testdb
EOF
```
Inspect the file to check that all settings are correct for your local setup.
In particular, the wikipedia path should point to the test directory in your
Nominatim source directory.
Now you can import the test database:
```
dropdb --if-exists test_api_nominatim
./utils/setup.php --all --osm-file nominatim-api-testdb.pbf 2>&1 | tee import.log
./utils/specialphrases.php --wiki-import | psql -d test_api_nominatim 2>&1 | tee -a import.log
./utils/setup.php --import-tiger-data 2>&1 | tee -a import.log
```
### Running the tests
To run all tests just go to the test directory and run make:
To run all tests just go to the build directory and run make:

To skip tests that require the test database, run `make no-test-db` instead.
For more information about the structure of the tests and how to change and
extend the test suite, see the [Testing chapter](Testing.md).

### 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.
