phpunit-bridge does not take composer settings into account when downloading phpunit #27753
Description
Symfony version(s) affected: 4
Description
phpunit-bridge/simple-phpunit seems to always download PHPUnit from github.com which is problematic if your build server does not have Internet access.
Our build server does not have Internet access, instead it uses a local Artifactory instance as a proxy/cache. Since phpunit-bridge always downloads from GitHub we can't run tests during our build.
How to reproduce
Configure composer to use a local repository, disable packagist and try to run phpunit in a server with no Internet access:
$ composer config repositories.my_local https://repository.example.com/api/composer/php-remote
$ composer config repo.packagist false
$ composer install
$ bin/phpunit
Possible Solution
Use composer to download phpunit.
