Developer information

This document contains information about ARC2 internals which are relevant for maintaining and extending ARC2.

Run test environment

To run test environment execute:

vendor/bin/phpunit

Tests are split into different groups currently:

• unit
• db_adapter_depended

You can run the unit group directly, but you need to set some environment variables for db_adapter_depended.

config.php

Currently, we use the following standard database credentials to connect with the database:

$dbConfig = array(
    'db_name' => 'arc2_test',
    'db_user' => 'root',
    'db_pwd'  => 'Pass123',
    'db_host' => '127.0.0.1',
);

If you have different credentials, copy the tests/config.php.dist to tests/config.php and set your credentials.

Editor

Please make sure your editor uses our .editorconfig file.

Docker setup

For ARC2 developers we recommend using our docker setup (see folder docker). It provides a pre-configured set of software (for PHP, DBS etc.) and allows quick switches between different software versions.

No matter if one needs a MariaDB 10.3 with PHP 7.2 or a PHP 5.6 with MySQL 5.7.0. If there is a docker container, it runs.

Start

In your terminal go to docker folder and run make. It will build and start the docker environment as well as log you in.

Docker and Travis

We use a very wide range of software-combinations to test ARC2. Currently, all combinations of supported versions of PHP and database systems (currently MySQL and MariaDB only) are checked.

Using a Docker setup for local development allows to switch the backend very easily. So, if a test with a certain DBS/PHP version combination fails, its very likely that you can reproduce it locally. Dont forget to run composer update after a switch to make sure appropriate software is used.
