PHP Getting Started with PHP Unit Testing Test Driven Development Test Driven Development

Tried every combination I could think of, to no avail.

I've been stuck on this portion of this quiz for the last half hour. I'm about to skip it and move on, but it'd be nice to know what it is that I'm doing perpetually wrong. The final attempt I gave to answering this riddle is:

use  PHPUnit\Framework\TestCase;

class MathTest extends TestCase
    function testEquation()
        $language = new Language('PHP');

        $this->assertEquals( "$language(creationDate)", 1994 );

The "$this->" line was the fill-in-the-blank portion...I get the "assertEquals" part correct, but the parameters thereof are what keep slipping me up. Any help with this would be most appreciated. Thanks!

Perhaps you had the order reversed in what you tried. The error message is "$language(creationDate)", 1994' is incorrect. assertEquals(mixed $expected, mixed $actual). So $expected, in this case 1994, comes first.

$this->assertEquals( 1994, $language->creationDate() );
