@stof Have you looked into this? Are you considering on merging it?

@MECU As a quick solution for running the tests on this you can add the following line under the require-dev section of the composer.json file: "phpunit/phpunit": "4.5.0".

Then just run a composer update and after that running the test suite should be as easy as executing: ./vendor/bin/phpunit

Hope this helps.
