## Installing Nominatim
The first step is to install Nominatim itself. Please follow the installation
instructions in the [Admin section](../admin/Installation.md). You don't need

-is sufficient.

+via `nominatim serve` is sufficient.
-If you want to run Nominatim in a VM via Vagrant, use the default `ubuntu` setup.
+If you want to run Nominatim in a VM via Vagrant, use the default `ubuntu24` setup.
Vagrant's libvirt provider runs out-of-the-box under Ubuntu. You also need to
install an NFS daemon to enable directory sharing between host and guest. The
following packages should get you started:
## Prerequisites for testing and documentation
The Nominatim test suite consists of behavioural tests (using behave) and
-unit tests (using PHPUnit for PHP code and pytest for Python code).
-It has the following additional requirements:
+unit tests (using pytest). It has the following additional requirements:
* [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)
+* [flake8](https://flake8.pycqa.org/en/stable/) (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)
+* [pytest-asyncio](https://pytest-asyncio.readthedocs.io)
For testing the Python search frontend, you need to install extra dependencies
depending on your choice of webserver framework:
-* [sanic-testing](https://sanic.dev/en/plugins/sanic-testing/getting-started.html) (sanic only)
-* [httpx](https://www.python-httpx.org/) (starlette only)
-* [asgi-lifespan](https://github.com/florimondmanca/asgi-lifespan) (starlette only)
+* [httpx](https://www.python-httpx.org/) (Starlette only)
+* [asgi-lifespan](https://github.com/florimondmanca/asgi-lifespan) (Starlette only)
The documentation is built with mkdocs:
* [mkdocs](https://www.mkdocs.org/) >= 1.1.2
-* [mkdocstrings](https://mkdocstrings.github.io/) >= 0.16
-* [mkdocstrings-python-legacy](https://mkdocstrings.github.io/python-legacy/)
+* [mkdocstrings](https://mkdocstrings.github.io/) >= 0.25
+* [mkdocs-material](https://squidfunk.github.io/mkdocs-material/)
+* [mkdocs-gen-files](https://oprypin.github.io/mkdocs-gen-files/)
-### Installing prerequisites on Ubuntu/Debian
+Please be aware that tests always run against the globally installed
+osm2pgsql, so you need to have this set up. If you want to test against
+the vendored version of osm2pgsql, you need to set the PATH accordingly.
-Some of the Python packages require the newest version which is not yet
-available with the current distributions. Therefore it is recommended to
-install pip to get the newest versions.
+### Installing prerequisites on Ubuntu/Debian
-To install all necessary packages run:
+The Python tools should always be run with the most recent version.
+The easiest way, to handle these Python dependencies is to run your
+development from within a virtual environment.
```sh
-sudo apt install php-cgi phpunit php-codesniffer \
- python3-pip python3-setuptools python3-dev
-
-pip3 install --user behave mkdocs mkdocstrings pytest pylint \
- mypy types-PyYAML types-jinja2 types-psycopg2 types-psutil \
- sanic-testing httpx asgi-lifespan
+sudo apt install libsqlite3-mod-spatialite
```
-The `mkdocs` executable will be located in `.local/bin`. You may have to add
-this directory to your path, for example by running:
+To set up the virtual environment with all necessary packages run:
-```
-echo 'export PATH=~/.local/bin:$PATH' > ~/.profile
+```sh
+virtualenv ~/nominatim-dev-venv
+~/nominatim-dev-venv/bin/pip install\
+ psutil psycopg[binary] PyICU SQLAlchemy \
+ python-dotenv jinja2 pyYAML datrie behave \
+ mkdocs mkdocstrings mkdocs-gen-files pytest pytest-asyncio flake8 \
+ types-jinja2 types-markupsafe types-psutil types-psycopg2 \
+ types-pygments types-pyyaml types-requests types-ujson \
+ types-urllib3 typing-extensions unicorn falcon starlette \
+ uvicorn mypy osmium aiosqlite
```
-If your distribution does not have PHPUnit 7.3+, you can install it (as well
-as CodeSniffer) via composer:
+Now enter the virtual environment whenever you want to develop:
-```
-sudo apt-get install composer
-composer global require "squizlabs/php_codesniffer=*"
-composer global require "phpunit/phpunit=8.*"
+```sh
+. ~/nominatim-dev-venv/bin/activate
```
-The binaries are found in `.config/composer/vendor/bin`. You need to add this
-to your PATH as well:
+### Running Nominatim during development
+
+The source code for Nominatim can be found in the `src` directory and can
+be run in-place. The source directory features a special script
+`nominatim-cli.py` which does the same as the installed 'nominatim' binary
+but executes against the code in the source tree. For example:
```
-echo 'export PATH=~/.config/composer/vendor/bin:$PATH' > ~/.profile
+me@machine:~$ cd Nominatim
+me@machine:~Nominatim$ ./nominatim-cli.py --version
+Nominatim version 4.4.99-1
```
+Make sure you have activated the virtual environment holding all
+necessary dependencies.
## Executing Tests
All tests are located in the `/test` directory.
-To run all tests just go to the build directory and run make:
+To run all tests, run make from the source root:
+
+```sh
+make tests
+```
+
+There are also make targets for executing only parts of the test suite.
+For example to run linting only use:
```sh
-cd build
-make test
+make lint
```
+The possible testing targets are: mypy, lint, pytest, bdd.

extend the test suite, see the [Testing chapter](Testing.md).

-To build the documentation, go to the build directory and run
+To build the documentation run
```
make doc
-INFO - Cleaning site directory
-INFO - Building documentation to directory: /home/vagrant/build/site-html

+For local testing, you can start webserver:
```
