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?



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:


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);


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

Ah yeah that works thanks very much! :-)
