This repo is a test of whether you can use Composer's require command to install Drupal 8's drupal/core package as a useful dependency under vendor/.
It uses github and travis-ci to build the project, and then tries to run tests.
We only have one PHPUnit-based test to start. It tries to access the container from \Drupal.
This project contains a composer.json file which requires drupal/core 8.3.* and phpunit/phpunit <5.
drupal/core has a dev requirement of phpunit, but dev requirements are ignored for non-root projects. Therefore it's necessary to require phpunit here.
You can check the work here by doing it locally:
composer install
./vendor/bin/phpunit
