Does it make sense to test a method that simply hands off work to another method?

Question

PHP

There is this in the code:

public function checkStatuses()
    {
        if (!empty($this->getCollectionByStatus('ball'))) {
            $this->provider->filterDataByName('ball');
        }

        return $this;
    }

A method that simply passes work to another class and its method to work. If I write a unit test for the checkStatuses method, how logical is it in principle, despite the fact that this is a method that delegates work to another?

Answer 1

If this is not a private method, then it is necessary. Why? Because tests are responsible not only for the fact that the code works as expected, but also that it has not changed its behavior
