I have Magento 2.3 and I want to use Magento Functional Testing Framework version 2.3 but when I run the command vendor/bin/mftf run:test AdminLoginTest to run the test, the following error occurs:
==== Redirecting to Composer-installed version in vendor/codeception ====
Fatal error: Uncaught Error: Call to undefined function Codeception\Lib\codecept_absolute_path() in /Users/hanhan/Deskto
p/workspace/magento2/vendor/codeception/codeception/src/Codeception/Lib/ParamsLoader.php:25
In the file PramsLoader.php, codecept_absolute_path() method is invoked and it gives the error because this method is not defined
$this->paramsFile = codecept_absolute_path($paramStorage);
How can i solve this ?
I happened to encounter the same error today. It's because there is an old vendor directory in dev/tests/acceptance where previously we store composer.json file and now moved to root. Deleting dev/tests/acceptance/vendor folder resolve the fatal error.
