I have set up a Maven project using Selenium WebDriver and integrated TestNG. However, when I validate my Maven project, an error message is displayed stating "Attribute "parallel" with value "none" must have a value from the list "false methods tests classes instances" in testng-failed.xml and also in testng.xml.
Can someone please assist me in resolving this issue?
