What is wrong with this code?

When checking this code it says:

"Bummer: You must assert that the expected result matches the actual result."

What am i doing wrong?

Cheers!

index.php
<?php

use PHPUnit\Framework\TestCase;

class MathTest extends TestCase
{
  /** @test */
  public function Addition() {
    $expected = 4;
    $actual = 2 + 2;

    assert('$actual === $expected');
  }
}

?>

I downloaded the project files and PigLatinTest.php gives an example of what the challenge is looking for:

<?php

use PHPUnit\Framework\TestCase;
//require_once __DIR__.'/../src/PigLating.php';

class PigLatinTest extends TestCase
{
    /** @test */
    function convertSingleStartingConsonantWordToPigLatin()
    {
        $word = 'test';
        $expectedResult = 'esttay';

        $pigLatin = new PigLatin();
        $result = $pigLatin->convert($word);

        $this->assertEquals(
            $expectedResult,
            $result
        );
    }
}

You should use assertEquals(). There is an explanation and another example here. Or the documentation here.

Ah yeah that works thanks very much! :-)
