Test factory method

Question

Write tests to cover 100% code - this is what we should try to achieve. But I came across a situation where I do not know how to test a method (factory method):

public function getDocument(){
    $document = new Document();
    $document->settings(new Settings());
    $document->filesystem(new Filesystem('e:'));
    return $document;
}

The purpose of this method is a shortcut to create a document, 3 lines are written each time.

How to check this method?

Or maybe this is the situation, why do we have a @codeCoverageIgnoreStart block? For this reason, PHPUnit provides this kind of annotation.

---

EDIT: The main idea of ​​this method is to make life easier for the client. Nothing more, no configuration, etc. (But the method will be a good place for this).

//I don't want bother client with Settings() and Filesystem('e:')
$document = new Document(new Settings(), new Filesystem()); //NO
$document = Files.getDocument() //much easier and shorter.

//Changing API to getDocument($var, $var) make no sense, the same thing I could have normally.
$document = new Document(new Settings(),new Filesystem('e:'));

Perhaps I should think about whether I really need to provide this method, the user who wants to use the document should know about the dependencies, he should not hide.
