php-symfonyUnit testing in PHP Symfony example

Unit testing is a process of testing individual units of code in order to ensure that they are working as expected. In PHP Symfony, unit testing is done using PHPUnit.

Example code

<?php

namespace App\Tests;

use PHPUnit\Framework\TestCase;

class ExampleTest extends TestCase
{
    public function testExample()
    {
        $this->assertTrue(true);
    }
}

Output example

OK (1 test, 1 assertion)

Code explanation

• namespace App\Tests; - declares the namespace of the test class
• use PHPUnit\Framework\TestCase; - imports the TestCase class from the PHPUnit framework
• class ExampleTest extends TestCase - declares the test class which extends the TestCase class
• public function testExample() - declares the test method
• $this->assertTrue(true); - asserts that the given expression is true
