Question

Why I\'m getting this PHP error?

Fatal error: Class \'PHPUnit_Framework_TestCase\' not found in ...

Answer 1

For higher version of phpunit such as 6.4 You must use the namespace PHPUnit\Framework\TestCase

use TestCase instead PHPUnit_Framework_TestCase

// use the following namespace
use PHPUnit\Framework\TestCase;

// extend using TestCase instead PHPUnit_Framework_TestCase
class SampleTest extends TestCase {

}
