use Fuel\Core\Config;
/**
 * @command php oil test --group=Admins
 * @command for this only >>> php oil test --file=fuel/app/tests/controller/admins.php
 * @group Admins
 */
class Test_Controller_Admins extends \TestCase {


    public function test_action_detail() {
        $this->assertTrue(true);
    }

    /**
     * setUp method
     *
     * @return void
     */
    public function setUp() {
        parent::setUp();
    }

    /**
     * tearDown method
     *
     * @return void
     */
    public function tearDown() {
        parent::tearDown();
    }

}

I solved it in this way. In below I places the steps how i solved it. this worked for me. Easiest way to obtain PHPUnit is to download a PHP Archive (PHAR).

(1) Install PHPUNIT globally

wget https://phar.phpunit.de/phpunit.phar
chmod +x phpunit.phar
sudo mv phpunit.phar /usr/local/bin/phpunit
phpunit --version

(2) Copy "fuel/packages/oil/config/oil.php" to "fuel/app/config/oil.php"

(3) Change the binary path to

 'binary_path' => VENDORPATH.'bin/phpunit',  

(4) now test your fuelphp

 fuelphp oil test
