How to write a unit test for Yii2?

Question

Yii

I’m getting familiar with the new Yii2, I pulled up this repository:
https://github.com/yiisoft/yii2
Then I pulled up the files using composer in the advanced
application I started looking towards tests, I had never worked with them before, so I had difficulty understanding this affairs. So
we have folders with tests in the following directories: backend, common, console , frontend for the test. The contents of this folder is: https://github.com/yiisoft/yii2/tree/master/apps/a...


Honestly, I almost didn’t understand what we have here and why, most likely different test frameworks are used, but I saw the familiar name unit and got there.
Well, and then my powers are all. Ie, please tell me how to write your first test, what is going on there?

Answer 1

Codeception is good, but not required. You can only use phpunit, especially since you have already installed it. Create file FirstTest.php in tests\unit folder with this content

<?php

namespace tests\unit;

class FirstTest extends \PHPUnit_Framework_TestCase
{
    public function testTrue()
    {
        $this->assertTrue(true);
    }
}

and run the test with the command
Your first test is ready
