Catch an error as exception

问题

Given the following code:

<?php

class Language
{
    private $code;

    public function __construct(string $code)
    {
        $this->code = $code;
    }
}

$lang = new Language();

I will get an ArgumentCountError like this:

Uncaught ArgumentCountError: Too few arguments

Now I would like to test and ensure this beahviour with a phpUnit unit test like this one:

class LanguageTest
{
    public function testLanguageConstructorWillRequireACode()
    {
        $language = new Language();

        $this->expectException(MissingArgumentException::class);
    }
}

But php interpeter raise an error and not an exception.

What would be the most idiomatical and correct way to do this?
