Running Tests

Prerequisites

PHPUnit

phpBB unit tests use the PHPUnit framework (see http://www.phpunit.de for more information). Version 3.5 or higher is required to run the tests. PHPUnit can be installed via Composer together with other development dependencies as follows.

$ cd phpBB
$ php ../composer.phar install --dev
$ cd ..

PHP extensions

Unit tests use several PHP extensions that board code does not use. Currently the following PHP extensions must be installed and enabled to run unit tests:

• ctype (also a PHPUnit dependency)
• dom (PHPUnit dependency)

Some of the functionality in phpBB and/or the test suite uses additional PHP extensions. If these extensions are not loaded, respective tests will be skipped:

• apc (APC cache driver)
• bz2 (compress tests)
• interbase, pdo_firebird (Firebird database driver)
• mysql, pdo_mysql (MySQL database driver)
• mysqli, pdo_mysql (MySQLi database driver)
• pdo (any database tests)
• pgsql, pdo_pgsql (PostgreSQL database driver)
• simplexml (any database tests)
• sqlite, pdo_sqlite (SQLite database driver, requires SQLite 2.x support in pdo_sqlite)
• zlib (compress tests)

Database Tests

By default all tests requiring a database connection will use sqlite. If you do not have sqlite installed the tests will be skipped. If you wish to run the tests on a different database you have to create a test_config.php file within your tests directory following the same format as phpBB's config.php. An example for mysqli can be found below. More information on configuration options can be found on the wiki (see below).

<?php
$dbms = 'mysqli';
$dbhost = 'localhost';
$dbport = '';
$dbname = 'database';
$dbuser = 'user';
$dbpasswd = 'password';

It is possible to have multiple test_config.php files, for example if you are testing on multiple databases. You can specify which test_config.php file to use in the environment as follows:

$ PHPBB_TEST_CONFIG=tests/test_config.php phpunit

Alternatively you can specify parameters in the environment, so e.g. the following will run PHPUnit with the same parameters as in the shown test_config.php file:

$ PHPBB_TEST_DBMS='mysqli' PHPBB_TEST_DBHOST='localhost' \
  PHPBB_TEST_DBNAME='database' PHPBB_TEST_DBUSER='user' \
  PHPBB_TEST_DBPASSWD='password' phpunit

Special Database Cases

In order to run tests on some of the databases that we support, it will be necessary to provide a custom DSN string in test_config.php. This is only needed for MSSQL 2000+ (PHP module), MSSQL via ODBC, and Firebird when PDO_Firebird does not work on your system (https://bugs.php.net/bug.php?id=61183). The variable must be named $custom_dsn.

Examples: Firebird using http://www.firebirdsql.org/en/odbc-driver/

$custom_dsn = "Driver={Firebird/InterBase(r) driver};dbname=$dbhost:$dbname";

MSSQL

$custom_dsn = "Driver={SQL Server Native Client 10.0};Server=$dbhost;Database=$dbname";

The other fields in test_config.php should be filled out as you would normally to connect to that database in phpBB.

Additionally, you will need to be running the DbUnit fork from https://github.com/phpbb/dbunit/tree/phpbb.

Running

Once the prerequisites are installed, run the tests from the project root directory (above phpBB):

$ phpBB/vendor/bin/phpunit

Slow tests

Certain tests, such as the UTF-8 normalizer or the DNS tests tend to be slow. Thus these tests are in the slow group, which is excluded by default. You can enable slow tests by copying the phpunit.xml.all file to phpunit.xml. If you only want the slow tests, run:

$ phpBB/vendor/bin/phpunit --group slow
