PHP Robot Name - tests say I don't enter arguments - don't understand it

Hi,

I am totally stuck in Robot Name. The returning tests keep saying that there aren’t enough arguments in the getName function. I wouldn’t know how to enter an argument except when the class is constructed with a constructor function or some other function that sets the name. I really don’t have a clue what to do now.

This is a test result :

Code Run

$this->assertMatchesRegularExpression('/^[a-z]{2}\d{3}$/i', $this->robot->getName());

Test Error

RobotNameTest::testHasName
ArgumentCountError: Too few arguments to function Robot::__construct(), 0 passed in RobotNameTest.php on line 39 and exactly 1 expected

RobotName.php:31
RobotNameTest.php:39

This is the instruction I’m trying to execute:

Manage robot factory settings.
When a robot comes off the factory floor, it has no name.
The first time you turn on a robot, a random name is generated in the format of two uppercase letters followed by three digits, such as RX837 or BC811.

This is what I’ve got so far

declare(strict_types=1);

class Robot
{
    private string $name;
    
    function __construct(string $robotName) {
        $this->name = $robotName;
    }
        
    public function getName(): string {
        return $this->name;
    }

    public function reset(): void
    {
        $robotName = $this->getName();
    }
}

Hold on, I’ve found it. I’m writing a setName function that will produce the name and then I can get it. I’m getting very different error messages now and passing two tests.
