Code Inspections & Tests

Code inspections are very important in order to maintain the same code quality throughout the application. The Build repository and package managers such as composer and npm contain all esential configuration files for the respective inspection tools. The framework and every module will be evaluated based on the defined code and quality standards. Only code that passes all code, quality and test standards are accepted. Updates and bug fixes also must follow the standards.

How and what to test?

In this project multiple levels of tests must be implemented such as unit tests, integration tests and system tests.

The following testing requirements must be met:

• 90% code coverage in the tests
• all tests must pass without warnings, errors and exceptions
• no warnings and errors during static code inspections
• no usage of deprecated function calls
• no code style violations
• every test should have a short description for the test report

Unit tests

Every test must be in it's own test function. Every public function must have a unit test

Integration tests

System tests

Tools

Tools used for the code inspection are:

• PHPUnit
• PHPStan
• Jasmine
• PHPCS
• Custom scripts/tools

These tools are all installed by running the setup.sh script from the Build repository.

PHPUnit

This application uses PHPUnit as unit testing framework. Unit tests for specific classes need to be named in the same manner as the testing class.

In order to run all tests and also creating the dummy data for UI tests, execute the following command:

php vendor/bin/phpunit -c tests/PHPUnit/phpunit_no_coverage.xml

In order to also create a code coverage report run:

php vendor/bin/phpunit -c tests/PHPUnit/phpunit_default.xml

Modules

Every module needs to have a Admin directory containing a class called AdminTest.php which is used for testing the installation, activation, deactivation, uninstall and remove of the module. Tests that install, update, remove etc. a module need to have a group called admin. After running the AdminTest.php test the final state of the module should be installed and active, only this way it's possible to further test the controller and models. A code coverage of at least 80% is mandatory for every module for integration.

PHPStan

With phpstan the code base is statically analyzed based on its configuration. This will help you to follow some of the "best" practices we enforce.

php vendor/bin/phpstan analyse --autoload-file=phpOMS/Autoloader.php -l 8 -c Build/Config/phpstan.neon --error-format=prettyJson ./ > Build/test/phpstan.json

Jasmine

The javascript testing is done with jasmine. The javascript testing directory is structured the same way as the Framework. Unit tests for specific classes need to be named in the same manner as the testing class.

PHP CS

Besides the code tests and static code analysis the code style is another very imporant inspection to ensure the code quality.

php vendor/bin/phpcs ./ --standard="Build/Config/phpcs.xml" -s --report-junit=Build/test/junit_phpcs.xml

Git Hooks (Linux only)

The git hooks perform various checks and validations during the commit and warn the developer about invalid code or code style/guideline violations.

For developers it is recommended to copy the contents of the default.sh file in the Build repository under Hooks to your pre-commit file in the .git/hooks directory. If the pre-commit file doesn't exist just create it.

The same should be done with every module. Simply go to .git/modules/**/hooks and also add the content of the default.sh file to all pre-commit files.

By doing this every commit will be inspected and either pass without warnings, pass with warnings or stop with errors. This will allow you to fix code before committing it. Be aware only changed files will be inspected. Also make sure all pre-commit have +x permissions.
