PHP Laravel GitLab

https://cylab.be/blog/95/test-your-laravel-project-with-gitlab

So you have a Laravel project, and as a good programmer you are using GitLab to manage your code, and you started implementing some phpunit tests. But how to run these tests in GitLab?

env.gitlab

First, you'll need a custom .env file that will be used for the tests. Let's call it env.gitlab. Here is a starting point that you can tweak to your needs.

APP_NAME="My awesome app"
APP_ENV=test
APP_KEY=base64:/nTMW3a12345678901234567890Ecv/ALCcT+TbaVU4=
APP_DEBUG=true
APP_URL=http://172.0.0.1:8000

LOG_CHANNEL=stack

DB_CONNECTION=sqlite
DB_DATABASE=db.sqlite

BROADCAST_DRIVER=log
CACHE_DRIVER=file
QUEUE_CONNECTION=sync
SESSION_DRIVER=file
SESSION_LIFETIME=120

REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

MAIL_MAILER=log

EMAIL_VERIFICATION_EXPIRATION_TIME=60

APP_TIMEZONE="Europe/Brussels"

The main attention points here are:

  • APP_DEBUG is true so we get some feedback if the tests fail
  • DB_CONNECTION is sqlite so we don't need to setup a MySQL database for the tests
  • QUEUE_CONNECTION is sync so we don't need an external process to run our queue jobs
  • MAIL_MAILER is log, so the mails are simply written to the log file, and not sent for real...

.gitlab-ci.yml

Now we can create the file .gitlab-ci.yml (don't forget the leading dot) that will instruct GitLab how to test our app. Once again, here is a starting point:

# this docker image contains PHP 7.4, composer and some other goodies
# you can find the full recipe (Dockerfile) here
# https://gitlab.cylab.be/cylab/docker-images/-/blob/master/php/php7.4
image: cylab/php74

test:
  before_script:
    # use our custom .env file
    - cp env.gitlab .env

    # install the application
    - COMPOSER_CACHE_DIR=composer-cache composer install
    - php artisan key:generate
    - touch storage/app/db.sqlite
    - php artisan migrate

    # Optionally, we can install nodejs to build our js and css files
    - curl -sL https://deb.nodesource.com/setup_10.x | bash -
    - apt install nodejs -y
    - npm install
    - npm run prod

  # run the tests
  script:
    - vendor/bin/phpunit

  # what we want to store locally to speed up the next run of this job
  cache:
    paths:
      - composer-cache/
      - node_modules/

In this file:

  • We use a Docker image cylab/php74 that contains PHP 7.4 (obviously) but also some additional modules and goodies.
  • There is only one job called test, to keep our pipeline clean and fast. We can define multiple jobs and stages if we need to run the tests with different Docker images, for example to test with different versions of PHP...
  • We instruct composer to use a custom directory to store downloaded libraries (namely composer-cache) and put these files in cache, so they can be reused at the next execution of the job. This allows to reduce the amount of downloaded libraries. Other files like bootstrap are not put in cache because these would simply pollute the next execution of the job and might corrupt the results of the tests.

commit and push

Finally, we can commit and push this all to GitLab:

git add env.gitlab
git add .gitlab-ci.yml
git commit -m "test with gitlab"
git push

gitlab-ci

Once this basic tests are configured, don't hesitate to add:

Fully customizable emails using Laravel 9
With the release of Laravel 9, the Swift Mailer (that is no longer maintained) has been replaced by the Symfony Mailer. You can already find some useful information about this change along all the other ones in the Upgrade Guide from Laravel 8.x to 9.0. However this guide does not contain enough information if you want to send fully customized emails. This blog post proposes you a solution coming directly from the Symfony documentation!
SQL injection with SQLMap
Code injection is one of the most critical web application vulnerabilities. Indeed, the consequences of code injection can be dramatic (impact). Moreover, still today a lot of web applications are vulnerable to code injection (frequency). Finally, some tools like SQLMap allow to automatically detect and use these vulnerabilities (exploitation). For this reason, the vulnerability is listed in the top 10 published by the Open Web Application Security Project (OWASP) [1]. In this blog post, we will present one type of code injection, called SQL injection, and we will show how to perform a SQL injection attack with SQLMap.
Filter USB devices with udev (and some PHP code)
USB devices can be a liability : they can be used to exfiltrate data from a computer or server, to plug a hardware keylogger, or to plant a malware. Hence on a managed computer, USB devices should be filtered and whitelisted. In this blog post we show how this can be achieved thanks to udev, and some PHP code.
