PHPunit Uncaught Error: Call to undefined method PHPUnit_Util_Configuration::getTestdoxGroupConfiguration()

Seems like your version installed globally does not meet minimal required version. Try to run

phpunit --version

I bet you will get some like 5.1. The php artisan dusk command uses different version which is located in vendor/bin/phpunit. So, you are also able to use this version instead. Just type:

vendor/bin/phpunit

instead of phpunit. You have to upgrade your global phpunit version if it works.

Had the same problem at Laravel 5.4. This worked for me.

Step 1: update your composer

composer update

Step 2: run the phpunit

vendor/bin/phpunit

You can run a specific test by specifying the file

vendor/bin/phpunit tests/Feature/ExampleTest.php

In my case the following command worked in windows environment, with \ in place of /:

vendor\bin\phpunit
