## 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)
### Installing prerequisites on Ubuntu/Debian
The Python tools should always be run with the most recent version.
-In particular, pylint tends to have a lot of breaking changes between versions.
The easiest way, to handle these Python dependencies is to run your
development from within a virtual environment.
```sh
-sudo apt install libsqlite3-mod-spatialite php-cli
+sudo apt install libsqlite3-mod-spatialite
```
To set up the virtual environment with all necessary packages run:
~/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 pylint \
+ 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 \
. ~/nominatim-dev-venv/bin/activate
```
-For installing the PHP development tools, run:
-
-```sh
-sudo apt install php-cgi phpunit php-codesniffer
-```
-
-If your distribution does not have PHPUnit 7.3+, you can install it (as well
-as CodeSniffer) via composer:
-
-```
-sudo apt-get install composer
-composer global require "squizlabs/php_codesniffer=*"
-composer global require "phpunit/phpunit=8.*"
-```
-
-The binaries are found in `.config/composer/vendor/bin`. You need to add this
-to your PATH:
-
-```
-echo 'export PATH=~/.config/composer/vendor/bin:$PATH' > ~/.profile
-```
-
### Running Nominatim during development
The source code for Nominatim can be found in the `src` directory and can
