Magento 2 mftf Could not parse any test in xml

I have followed the steps written in the devdocs for MFTF tetsing, but when i come to the step where i have to run-
vendor/bin/mftf generate:tests

This error shows up-

Could not parse any test in xml. in
C:xampphtdocsmagentomagecomvendormagentomagento2-functional-testing-frameworksrcMagentoFunctionalTestingFrameworkTestHandlersTestObjectHandler.php
on line 137

Any idea on how i could solve this problem?
