I am trying to develop TestNG Framework with the help of Selenium. I have developed HomePage, LoginPage, ProfilePage, NewPostPage, DraftsPage. While I was running the DraftsPageTest.java, @BeforeMethod was working fine and the moment control comes to @Test, homepage.draftsPage(); is also working fine. But the moment control comes to draftspage.toggleMenu(); it is throwing
java.lang.NullPointerException.
Any help will be highly appreciated.
Thanks in advance:)
