I added the test for the valid method to the code, it checks this case

    // to file zf2/tests/ZendTest/Stdlib/PriorityListTest.php
    public function testValid() 
    {

    $position = 0;


        $this->list->insert('foo',    'foo_value');
        $this->list->insert('bar',    'bar_value');
        $this->list->insert('baz',    false);
        $this->list->insert('foobar', 'fobar_value');
        $this->list->insert('barbaz',  'barbazvalue');


        foreach($this->list as $value)
        {
            ++$position;
        }

        $this->assertEquals(5, $position);
    }

I already created PR #6773 for it. Duplicate, please close this.

I think you forgot to add the test file to this PR, but as this is a duplicate it is not needed anymore.
