Functional Testing
Functional testing evaluates the application’s behavior from an end-user perspective. It tests the system’s functionality against specific requirements, simulating user interactions to validate that the application performs as expected. Functional testing evaluates the entire system’s functionality from the end-user perspective. Test user interactions and expected outcomes. Use assertions to validate system behavior.
Example: This example shows the Functional Testing.
<?php
require_once 'FileProcessor.php';
use PHPUnit\Framework\TestCase;
class FileProcessorFunctionalTest extends TestCase {
public function testFileProcessing() {
$processor = new FileProcessor();
$processed = $processor->processFile('test.txt');
$this->assertTrue($processed);
}
}
<?
class FileProcessor {
public function processFile($filename) {
// Simulate file processing logic
return file_exists($filename);
}
}
Output:
Note: “Vendor/bin/phpunit TestFileName” will be used to run the test.
