When writing unit tests in PHP, it's essential to ensure your code behaves as expected. You can use PHPUnit, a powerful testing framework that allows you to automate and manage your tests efficiently.
Here’s a quick example of how to write a simple unit test using PHPUnit:
assertEquals(4, $calculator->add(2, 2));
}
}
?>
To run your tests, you can execute the PHPUnit command in your terminal:
phpunit CalculatorTest
