How can PHP developers test and verify the behavior of session handling in their applications?

To test and verify the behavior of session handling in PHP applications, developers can use tools like PHPUnit to write unit tests for their session handling code. These tests can cover scenarios such as setting session variables, retrieving session data, and destroying sessions to ensure that the session handling functions as expected. 

// Example PHPUnit test case for session handling

use PHPUnit\Framework\TestCase;

class SessionTest extends TestCase {
    
    public function testSetSessionVariable() {
        session_start();
        $_SESSION['test_variable'] = 'test_value';
        $this->assertEquals('test_value', $_SESSION['test_variable']);
        session_destroy();
    }
    
    public function testDestroySession() {
        session_start();
        $_SESSION['test_variable'] = 'test_value';
        session_destroy();
        $this->assertEmpty($_SESSION);
    }
}
