InvalidArgumentException within PHPUnit

Thank you for the reply!! I understood, but where is the InvalidArgumentException::class comes from?

Hi there, MIHA W.LEE ! So let's take a look at this test:

/** @test */
    function ingredientMustEnterValidAmount()
    {
        $this->expectException(InvalidArgumentException::class);
        //$this->expectExceptionMessageRegExp('/^The amount must be a float/');
        $recipe = new Recipe("Recipe Title");
        $recipe->addIngredient("garlic", "two", 'tbl'); 
    }

The problem here is what we're passing into the addIngredient method of the Recipe class. If you'll take a look in the "classes" folder and find Recipe.php on line 56 we have the declaration of the addIngredient method. It takes three things, an item, an amount, and a measurement. But the amount and measurement have default values of null. But take a look at lines 58 through 60. It says that if $amount is not null and it is also not of type float, then throw a new InvalidArgumentException.

if ($amount != null && !is_float($amount) && !is_int($amount)) {
            throw new InvalidArgumentException("The amount must be a float: " . gettype($amount) . " $amount given");
}

We tried to pass in the string "two" instead of the float 2.0 or the integer 2. This is what is throwing the exception. So it would produce "The amount must be a float: string two given". This method will not accept any data type for $amount except a float or int. And any integer can always be converted to a float. So it's important that $amount is one of the two

Hope this helps!

Sorry for my late reply. Thank you very much!! Finally I understood!!!

Dear Teacher Jennifer Nordell,

I was trying to log into the slack, but I couldn't. The slack sent the email and tell me, 'you should reactivate your account'. I don't know how to do it, can teacher please tell me how to do?

Thank you very much and have nice day

Hey, MIHA W.LEE! Not sure what happened, but I've reactivated your account on slack. You should be able to log in now

Thank you teacher Jennifer Nordell. I successfully logged into the slack, but I only saw the unit01 in the slack, the other units didn't appear over the slack.
