Depending if you run just a single file or the entire suite(s), Codeception will inject `App\Tests\Support\UnitTester` or your bundle's `MyBundle\Tests\Support\UnitTester` into your `*Test.php` files. This might lead to an error message like:
> [TypeError] Cannot assign MyBundle\Tests\Support\UnitTester to property MyBundle\Tests\Unit\MyTest::$tester of type App\Tests\Support\UnitTester
The simplest way to deal with this is to just add both runners as a union type hint: ```php <?php protected \MyBundle\Tests\Support\UnitTester|\App\Tests\Support\UnitTester $tester; ```
