I\'m just test playing with Php unit.
Here is my DependencyFailureTest class:
require_once \'../vendor/autoload.php\';
use PHPUnit\\Framework\\TestC
It must be a configuration issue. I copied your code and ran it on the command line with verbose and it worked fine with version 5.4.6.
I would reinstall phpunit and ensure you have the latest version.
Also, their sample test case from their Getting Started page is:
negate();
// Assert
$this->assertEquals(-1, $b->getAmount());
}
// ...
}

Notice the difference in your extension usage, although I don't think it is an issue, if you use their declaration as stated, it helps to isolate the problem.
