PHP Fatal error: Uncaught Error: Call to undefined method PHPUnit\Util\Configuration::getExtensionConfiguration()

Question

I am trying to follow the instructions here https://laravel.com/docs/5.6/testing. On the Environment section here what I did.

php artisan env --env=testing

and then run

phpunit

but after that, this message show up

PHP Fatal error:  Uncaught Error: Call to undefined method PHPUnit\Util\Configuration::getExtensionConfiguration() in /mnt/c/projects/www/janicalizdotcom/vendor/phpunit/phpunit/src/TextUI/TestRunner.php:953
Stack trace:

  thrown in /mnt/c/projects/www/janicalizdotcom/vendor/phpunit/phpunit/src/TextUI/TestRunner.php on line 953

What is that mean? and what I should do about it?

I have no idea since its the first time running laravel test

Answer 1

If just phpunit works that means that you have a global installation of PHPUnit. You probably want to use vendor/bin/phpunit instead.
