Share your experience in software testing.

In the field of software testing, I have used various approaches and tools to ensure code quality and application stability.

• Unit testing: I wrote tests for individual functions and classes using PHPUnit. This allowed for quick detection of errors early in development.

• Integration testing: I checked the interaction between system components, such as working with databases and external APIs.

• Functional testing: I used tools for automating user scenario testing, such as Behat or Codeception.

• Performance and load testing: I applied profiling and load testing to identify bottlenecks.

• CI/CD integration: I configured automatic test runs on commits, which helped maintain code stability.

An example of a simple unit test in PHP with PHPUnit:

use PHPUnit\Framework\TestCase;

class CalculatorTest extends TestCase {
    public function testAdd() {
        $calc = new Calculator();
        $this->assertEquals(4, $calc->add(2, 2));
    }
}

This approach helps ensure high quality and reliability of software.
