How to use PHPUnit for testing?

PHPUnit is a unit testing framework for the PHP language. Most of the site owners want to implement PHPUnit testing because then we can simply use commands for testing. If you don’t know PHPUnit and don’t know how to test and use it, then just follow the example below to learn.

Here I will give a very simple PHPUnit example and how it works from scratch. I made a simple example using phpunit command. We need to create two files as follows:

1)MyTest.php

2)MyTestTests.php

Before starting the example, make sure you have installed PHP. So you just need to follow the file below to complete the example.

1. Download PHPUnit

wget https://phar.phpunit.de/phpunit.phar

php phpunit.phar --version

2. Create the MyTest.php file

<?php

class MyTest
{

    public function add($a, $b)
    {
        return $a + $b;
    }

}

3. Create MyTestTests .php file

<?php
require &#39;MyTest.php&#39;;

use PHPUnit\Framework\TestCase;

class MyTestTests extends TestCase
{
    private $mytest;

    protected function setUp()
    {
        $this->mytest = new MyTest();
    }

    protected function tearDown()
    {
        $this->mytest = NULL;
    }

    public function testAdd()
    {
        $result = $this->mytest->add(1, 3);
        $this->assertEquals(4, $result);
    }

}

Now we are ready to run the simple example below:

php phpunit.phar MyTestTests.php

You will find the result like this:
