Bootstrapping Symfony2 bundle tests with Composer

If you want to create an independent Symfony2 bundle, unit test are a must. Not only are they a good practice but they also help a lot with a day-to-day developpement work. There's one problem though - how do you bootstrap them when the bundle is not in a project?

A bootstrap file is needed to create the test environement. When you are creating basic unit tests, all you really need is an autoloader that will load all your dependencies. You will need to have them defined first, but I trust that you already have a composer.json file in your project.

Here is a sample Test/bootstrap.php file:
