Tell us about your practical experience in developing and implementing tests in projects

In PHP projects, I used PHPUnit for writing unit tests. The practice included creating tests for key business logic, such as verifying the correctness of class methods, data validation, and interaction with the database through mock objects.

I also implemented integration tests to check the operation of multiple components together, such as controllers and models in MVC.

An example of a simple test with PHPUnit:

use PHPUnit\Framework\TestCase;

class UserTest extends TestCase {
    public function testUserName() {
        $user = new User('Ivan');
        $this->assertEquals('Ivan', $user->getName());
    }
}

Additionally, I configured CI/CD pipelines for automatic test execution on each commit, which helped to promptly identify errors.
