How to use and save test result?

Hello guys I'm writing tests. And i dont know how to save result of first test in session. For example i add user. My first test is passed. But when it comes to second test its failed, beacuse he cant find user Malik. And thats why i need to save it. Please guy help me, im beginner at this. And sorry for my english! Thanks a lot!

public function testAddUser()
    {
        \App::$domain->***->***->AddHuman('Malik');
    }
public function testGivePresent()
    {
        \App::$domain->***->***->GivePresent('Malik', 'phone');
    }

if Im doing like that its okay, my test is ok

public function testAddUser()
    {
        \App::$domain->***->***->AddHuman('Malik');
        \App::$domain->***->***->GivePresent('Malik', 'phone');
    }
