Drop PHPUnit 4/5 fallback about php-swagger-test

[byjg]

Yeah, I see PHPUnit 5.* offers support to PHP 5.6, 7.0 and 7.1. The support for PHPUnit 5.3, 5.4 is no longer necessary.

I created a branch issue-13 for that.

Hi.

I also hate this fallback for PHPUnit, but since we support PHP5.6 I have to maintain this fallback OR drop the support for PHP 5.6 also;

Unfortunately I cannot drop the support for PHP 5.6 at this moment, but I am open for discuss alternatives to solve this problem. If you have some idea will be welcome.

Hi,

thanks for your answer. Ok, I get your point.
maybe it is possible to drop phpunit 4 only and increase to phpunit 5.4.

Cause this is the version when they introduced the \PHPUnit\Framework\TestCase class.
https://phpunit.de/manual/5.4/en/writing-tests-for-phpunit.html

less then 5.4 needs this fallback:
https://phpunit.de/manual/5.3/en/writing-tests-for-phpunit.html

Is this a possibility? So we can keep php 5.6 and remove the fallback.

Perfect. Thank you.
