#23927 (comment)
It seems that in php 5.3 tests pass, while in php 7 and 7.1 they don't pass. I can't figure out why. In my installation with 2.8 on php 7.0.10 I don't have problems. :(

PHP: 7 deps=high failure is normal, because was Installed symfony/form (2.8.x-dev 41d84cd) and your changes aren't there yet. (nothing to do).

PHP: 7.1 deps=low failure is understood, because was installed symfony/form (v2.7.25) (release) and your changes aren't there either, but you need update deps=low constraint in Bridge/Doctrine/composer.json for "symfony/form" to be able to test these changes.

Here is the missing patch @yceruto is talking about.
Would it be possible to have a test in the Form component also?
