Symfony session handler test suite

This repository contains a test suite for the Symfony session save handlers (to test locking support). Current handlers that can be tested (and their corresponding test mode) are:

• standard
  • default (NativeFileSessionHandler)
    Uses the "files" session module.
• strict (docs / rfc)
  • pdo_mysql (PdoSessionHandler)
    Stores data in MySQL using PDO.
  • memcached (MemcachedSessionHandler)
    Stores data in Memcache (fails: no locking).
  • redis (RedisSessionHandler)
    Stores data in Redis (fails: no locking).

Note that the standard mode testable handlers implement strict mode as well, but can't be tested as strict handlers.

Requirements

You can install the dependencies of this script using:

sudo apt install php-cli php-curl

Optional dependencies can be installed using:

sudo apt install memcached php-memcached redis php-redis php-mysql

You can install the Symfony dependencies of this script using:

wget getcomposer.org/composer.phar
php composer.phar install

You need PHP 7.4 or higher to run the code.

Running the tests

You should prepare your MySQL database by running the SQL script:

cat create_mysql_symfony_session_test_db.sql | sudo mysql

You can run the tests from the command line using:

php run-tests.php

The code will execute in about 1 second per handler and test 104 HTTP calls for each handler. The following output would mean that the tests succeeded and locking is implemented correctly (which is not the case):

standard - default   : OK
strict   - pdo_mysql : OK
strict   - memcached : OK
strict   - redis     : OK

The word "FAILED" appears on a failed test and "SKIPPED" is shown when the PHP module is not loaded for either Redis or Memcache.

Stress testing

Use this for 100 runs:

for i in `seq 1 100`; do php run-tests.php silent; done

As shown, you may use the argument "silent" to suppress output on successful or skipped tests.
