My problem is whenever the carpage.makeandmodel() is invoked in the @Test of TestConfused.java, a

Что я уже пробовал:
I am trying my hands on Selenium test automation using TestNG as the test framework. For this, I have used a Page Object pattern to model each of the pages of the website that I am writing the test for.
