Symfony Testing Workshop

Currently Using

  • Symfony ~3.0
  • Behat 3.1
  • PHPUnit 4.8

Installation with Git

Perform these steps in your shell:

git clone https://github.com/QafooLabs/symfony-testing.git
cd symfony-testing
composer install

Sometimes you need to generate a token for Github API, follow this docs:

https://getcomposer.org/doc/articles/troubleshooting.md#api-rate-limit-and-oauth-tokens

Installation with ZIP

Download the latest ZIP of the QafooLabs Symfony Testing repository. Unpack it into your workshop and rename the root directory to something less cryptic, for example just "symfony-testing".

Then open your shell and call composer:

cd symfony-testing
composer install

Verify it works

You can use the PHP builtin webserver to safe time configuring Apache or Nginx:

php app/console server:run

Click on the URL it displays to see if the page works. If it does not, please send me an email benjamin@qafoo.com.

Usage

php bin/phpunit
