How to write tests in Yii?

Question

Yii

For the second day I have been trying to figure out how to write tests in Yii and nothing comes of it.
According to this manual
php-md5.blogspot.com/2013/05/phpunit-selenium-rc-y...
I installed the whole thing with phpunit
Go to the folder:
\yii2\apps\advanced\frontend\tests\unit
Create my own first test MyOneTest.php :

use \yii\codeception\TestCase;

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

I also picked up an example from the manuals somewhere, I run: phpunit MyOneTest.php

F:\OpenServer\domains\portf.ru\yii2\apps\advanced\frontend\tests\unit>phpunit My
OneTest.php
PHP Fatal error:  Class 'yii\codeception\TestCase' not found in F:\OpenServer\do
mains\portf.ru\yii2\apps\advanced\frontend\tests\unit\MyOneTest.php on line 6

Fatal error: Class 'yii\codeception\TestCase' not found in F:\OpenServer\domains
\portf.ru\yii2\apps\advanced\frontend\tests\unit\MyOneTest.php on line 6

Wrote something like this:

class MyOneTest extends PHPUnit_Framework_TestCase
{
    public function testFailure()
    {
        $this->assertTrue(true);
    }
}

Everything seems to be working.

PHPUnit 3.7.32 by Sebastian Bergmann.

OK (1 test, 1 assertion)

But in this case, as I understand it, I will not have access to the Yii components in the test methods. Please tell me what to do?

Answer 1

well, you can't find the class \yii\codeception\TestCase. You probably didn't connect the YIi autoloader.

Answer 2

I don't know about Yii.
phpunit has a config - phpunit.de/manual/current/en/appendixes.configurat...
There you can specify bootstrap, a file that will be included when phpunit starts.
In it, apparently, you need to register autoload.

Answer 3

Everything works out of the box, you need to run it from the tests folder, there is a bootstrap file that loads all the necessary classes.
In this case, the command will be something like this:
Or all tests from the unit folder
phpunit --verbose unit
