Answer 1

First of all remove the unwanted testng dependency from the POM.xml and second you have added the scope as test in the testng dependency. You have also accessed the class file of the testng dependency with the scope test in src/main/java. Please remove the test scope from the dependency and then execute the test again. Let me know if the issue persists even after fixing the above issues.
