  Log Message:
  -----------
  Add support for PHPUnit 6 and 7 (#6870)

Fixes composer dependencies: Package phpunit/phpunit-mock-objects is abandoned

We cannot support v8 yet because of errors like:
Declaration of MailFunc::setUp() must be compatible with PHPUnit\Framework\TestCase::setUp(): void
It would require dropping PHP < 7.1 support.
