I don't think there is a way of mocking a function, but what you could do is use some kind of test double:

class SUT{
    $staticCreator = array('testA::staticABC'); //Initialized to a default 
             //for production, would be better if injected somehow before using

    function setStaticCreator($staticCreator){
        $this->staticCreator=$staticCreator;
    }
    function test(){
        return call_user_func($this->staticCreator);
    }
}

and then run your test this way:

class Test extends ...{
    function mockStaticABC(){
        return "mock_string";
    }

    test_testfunction(){
        $sut = new SUT();
        $staticCreator = array($this,'mockStaticABC');
        $sut->setStaticCreator($staticCreator);
        $mock_return = $sut->test();
        $this->assertEquals("mock_string",$mock_return);
    }
}
