## 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
* [PHP CodeSniffer](https://github.com/squizlabs/PHP_CodeSniffer)
-* [Pylint](https://pylint.org/)
+* [Pylint](https://pylint.org/) (2.6.0 is used for the CI)
+* [pytest](https://pytest.org)
The documentation is built with mkdocs:
sudo apt install php-cgi phpunit php-codesniffer \
python3-pip python3-setuptools python3-dev pylint
-pip3 install --user behave mkdocs
+pip3 install --user behave mkdocs pytest
```
The `mkdocs` executable will be located in `.local/bin`. You may have to add
| +- api Tests for API endpoints (search, reverse, etc.)
|
+- php PHP unit tests
+ +- python Python unit tests
+- scenes Geometry test data
+- testdb Base data for generating API test database
```
## PHP Unit Tests (`test/php`)
-Unit tests can be found in the php/ directory. They test selected php functions.
-Very low coverage.
+Unit tests for PHP code can be found in the `php/` directory. They test selected
+PHP functions. Very low coverage.
To execute the test suite run
UNIT_TEST_DSN='pgsql:dbname=nominatim_unit_tests' phpunit ../
It will read phpunit.xml which points to the library, test path, bootstrap
-strip and set other parameters.
+strip and sets other parameters.
It will use (and destroy) a local database 'nominatim_unit_tests'. You can set
a different connection string with e.g. UNIT_TEST_DSN='pgsql:dbname=foo_unit_tests'.
+## Python Unit Tests (`test/python`)
+
+Unit tests for Python code can be found in the `python/` directory. The goal is
+to have complete coverage of the Python library in `nominatim`.
+
+To execute the tests run
+
+ pytest test/python
+
## BDD Functional Tests (`test/bdd`)
Functional tests are written as BDD instructions. For more information on
