Use PHPUnit\Framework\TestCase instead of PHPUnit_Framework_TestCase

[carusogabriel]

I use the PHPUnit\Framework\TestCase notation instead of PHPUnit_Framework_TestCase while extending our TestCases. This will help us migrate to PHPUnit 6, that no longer support snake case class names.

I just need to bump PHPUnit version to ^4.8.35 and ^5.7, that support this namespace.

Thanks a lot for your PR. I believe ^4.8.35 || ^5.7 || ^6.0 should be OK as well.

Can you check why the tests are broken?

[carusogabriel]

@sagikazarmark I'll work on that

@sagikazarmark Tests fixed, and now we support PHPUnit 6 🏁

I just need to set backupGlobals="true" in our XML config file, to preserve some Session tests.

Any doubt, I used this article from @sebastianbergmann to help me in this update.

Just fyi, there is no reason to support 4.0 version, this is dev dependency. Thus not installed anywhere but in this project.

@carusogabriel many thanks for your work!

@TomasVotruba we still officially support PHP 5.5 and as of PHPUnit 5.0 the minimum PHP requirement is 5.6. So we still need PHPUnit 4.x for a while...but hopefully, not so long.
