Class 'Magento\TestFramework\TestCase\AbstractController' not found when running unit test for custom module

Question

I tried to make a unit test for my custom module like this:

app/code/MyCompany/UnitTest/Test/Unit/Controller/SpinTest.php

namespace MyCompany\UnitTest\Controller;

class SpinTest extends \Magento\TestFramework\TestCase\AbstractController
{
    public function testLogin()
    {
        $params = [
          'customer_id' => '3'
        ];
        $this->getRequest()->setPostValue($params);
        $this->dispatch('spin/run');
        $result = $this->getResponse()->getBody();
        $this->assertEquals('200', $result['status']);
    }
}

And ran the unit from terminal:

vendor/phpunit/phpunit/phpunit -c dev/tests/unit/phpunit.xml.dist app/code/MyCompany/UnitTest/Test/Unit/Controller/

But i got an error like this:

Class 'Magento\TestFramework\TestCase\AbstractController' not found in /var/www/mage2/app/code/MyCompany/UnitTest/Test/Unit/Controller/SpinTest.php on line 4

Answer 1

That class does not exist in Magento 2, so you got the error message. The \PHPUnit\Framework\TestCase class should be used for every TestCase in Magento 2.x.

So, your code should look like this:

namespace MyCompany\UnitTest\Controller;

class SpinTest extends \PHPUnit\Framework\TestCase
{
    public function testLogin()
    {
        $params = [
          'customer_id' => '3'
        ];
        $this->getRequest()->setPostValue($params);
        $this->dispatch('spin/run');
        $result = $this->getResponse()->getBody();
        $this->assertEquals('200', $result['status']);
    }
}
