Basic FatFreeFramework/Base->mock() + PHPUnit example

F3PHPUnitTest.php

<?php

class F3PHPUnitTest extends PHPUnit_Framework_TestCase {
	public function test() {
		$f3 = Base::instance();

		// Don't write to STDOUT
		$f3->set('QUIET', true);

		$f3->route('GET /path', function(){ echo 'TEXT'; });

		$this->assertNull($f3->mock('GET /path'));
		$this->assertSame('TEXT', $f3->get('RESPONSE'));
	}
}

Hello,
I have a problem with mock and phpunit

when I use base->mock() Assertion did not work $this->expectOutputString.
look here https://stackoverflow.com/questions/61594665/how-to-use-expectoutputstring-phpunits/61594808#61594808

For the record, this is not the whole problem, I hope it's not problem.
