Why is it impossible to access the connection through a getter?

Question

Yii

Hello!
I create a connection in the model:

function getTest(){
    return $this->hasOne( ... );
}

When working with a model, when accessing the relationship using $model->getTest()->prop, an error occurs.
$model->test->prop works fine.

Because if you access it as an attribute, this is one thing, but as a method, it's another.
$model->test analog of $model->getTest()->one()
