[SOLVED] Backend testing fixtures fails


I am having problem with testing backend tests.

When I run test on the backend I have the following error:

Test  tests/unit/models/TestNameTest.php:testFeature


  [RuntimeException] Call to undefined method backend\tests\UnitTester::haveFixtures 

TestNameTest class:


namespace backend\tests\models;

use Codeception\Util\Debug;

use common\fixtures\SomeModel as SomeModelFixture;

class TestNameTest extends \Codeception\Test\Unit



     * @var \backend\tests\UnitTester


    protected $tester;

    public function _before()



            'data' => [

                'class' => SomeModelFixture::className(),

                'dataFile' => codecept_data_dir() . 'some_modal_data.php'




    public function testFeature() {

        $data = $this->tester->grabFixture('data', 0);

        $model = new SomeModel(['scenario' => SomeModel::SCENARIO_ADMIN]);




Could anybody tell what is wrong with the test above?

\backend\tests\UnitTester (code below) exists in _support folder and it has correct namespacing as well.


namespace backend\tests;

Gues, any ideas? Maybe somebody already crossed this issue?

Solved, needed to add the following to unit.suite.yml file:

class_name: UnitTester
