+This chapter gives an overview how to set up Nominatim for development
and how to run tests.
!!! Important
## Prerequisites for testing and documentation
The Nominatim test suite consists of behavioural tests (using behave) and
-unit tests (using PHPUnit). It has the following additional requirements:
+unit tests (using PHPUnit for PHP code and pytest for Python code).
+It has the following additional requirements:
-* [behave test framework](https://behave.readthedocs.io) >= 1.2.5
-* [phpunit](https://phpunit.de) >= 7.3
+* [behave test framework](https://behave.readthedocs.io) >= 1.2.6
+* [phpunit](https://phpunit.de) (9.5 is known to work)
* [PHP CodeSniffer](https://github.com/squizlabs/PHP_CodeSniffer)
+* [Pylint](https://pylint.org/) (CI always runs the latest version from pip)
+* [mypy](http://mypy-lang.org/) (plus typing information for external libs)
+* [Python Typing Extensions](https://github.com/python/typing_extensions) (for Python < 3.9)
+* [pytest](https://pytest.org)
The documentation is built with mkdocs:
* [mkdocs](https://www.mkdocs.org/) >= 1.1.2
+* [mkdocstrings](https://mkdocstrings.github.io/)
### Installing prerequisites on Ubuntu/Debian
sudo apt install php-cgi phpunit php-codesniffer \
python3-pip python3-setuptools python3-dev
-pip3 install --user behave mkdocs
+pip3 install --user behave mkdocs mkdocstrings pytest \
+ pylint mypy types-PyYAML types-jinja2 types-psycopg2
```
The `mkdocs` executable will be located in `.local/bin`. You may have to add
## 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:
```sh
-cd test
-make
+cd build
+make test
```
-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).
Now you can start webserver for local testing
```
-build> mkdocs serve
+build> make serve-doc
[server:296] Serving on http://127.0.0.1:8000
[handlers:62] Start watching changes
```
to your host:
```
-build> mkdocs serve --dev-addr 0.0.0.0:8088
+build> PYTHONPATH=$SRCDIR mkdocs serve --dev-addr 0.0.0.0:8088
[server:296] Serving on http://0.0.0.0:8088
[handlers:62] Start watching changes
