Testing & Code Coverage

PHPUnit is used for unit testing. Unit tests ensure that class and methods does exactly what it is meant to do.

General PHPUnit documentation can be found at https://phpunit.de/documentation.html.

To run the PHPUnit unit tests, execute:

phpunit PATH/TO/PROJECT/tests/

If you want code coverage reports, use the following:

phpunit --coverage-html ./report PATH/TO/PROJECT/tests/

Used PHPUnit default config:

phpunit --configuration PATH/TO/PROJECT/phpunit.xml
