Calling setup and login methods throws NullPointer exception

Question

I'm having class with setup() and login().

Created another class Edit profile, calling setup and login in @BeforeClass and getting null poiinter exception.

    public class TestLogin {

        public static  WebDriver driver;// = new FirefoxDriver();
        public static String baseURL = Configuration.testsite;




        @BeforeTest
        @Parameters("browser")


            public void setup(String browser) throws Exception{

                //Check if parameter passed from TestNG is 'firefox'

                if(browser.equalsIgnoreCase("firefox")){

                //create firefox instance
                    driver = new FirefoxDriver();
                }

                //Check if parameter passed as 'chrome'
                else if(browser.equalsIgnoreCase("chrome")){
                    //set path to chromedriver.exe You may need to download it from http://code.google.com/p/selenium/wiki/ChromeDriver     
                    System.setProperty("webdriver.chrome.driver","//Users/eugeneshapo/Documents/chromedriver");
                    //create chrome instance
                    driver = new ChromeDriver();                       
                }

            else if(browser.equalsIgnoreCase("safari")){
                    //create chrome instance
                    driver = new SafariDriver();
                }
                else{
                    //If no browser passed throw exception
                    throw new Exception("Browser is not correct");
                }
                driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

            }


    //Login test
            @Test
            public void testLogin() throws InterruptedException{
                driver.get(baseURL);
                driver.manage().timeouts().implicitlyWait(20L, TimeUnit.SECONDS);
                analyticsLoginPage mylogin = PageFactory.initElements(driver, analyticsLoginPage.class);
                mylogin.verifylogin("username", "password");
                Thread.sleep(3000);
            }

@AfterTest
public static void quitDriver(){
     driver.quit();
        }       
    }

@Test//(dependsOnMethods = { "testLogin" })
public void verifyEditProfile() throws InterruptedException{

*****//instantiated web driver in the line below//

    WebDriver driver = new ChromeDriver();

    analyticsLandingPage landingpage = PageFactory.initElements(driver, analyticsLandingPage.class);
    analyticsEditProfilePage editprofile = PageFactory.initElements(driver, analyticsEditProfilePage.class);

    landingpage.gotoProfile();


    editprofile.verifyEditFirstName();
    editprofile.verifyEditLastName();
    editprofile.verifyCompanyName();
    editprofile.verifyReportingProfile();
    editprofile.verifyUsageStatistics();
}

    @AfterTest
    public static void quitDriver(){
         driver.quit();

}
}

can you poste the stack trace ? – MaximeF Feb 26 '16 at 03:14 — MaximeF, Feb 26 '16 at 03:14

The problem is in your code.

The reason why you see a null pointer exception in your Login() method [@BeforeClass annotated] is because you are calling

login.setup("chrome");

but you dont seem to have created an instance for login i.e.,

TestLogin login = new TestLogin();

is missing in your code.

Once you fix the problem you are most likely to see another NullPointerException in your EditProfile#verifyEditProfile() [ @Test annotated method ] because of the below line

analyticsLandingPage landingpage = PageFactory.initElements(driver, analyticsLandingPage.class);

Here you don't seem to have instantiated the driver instance and so it may also cause another NullPointerException

Thanks Krishnan. I'm able to login. But you are right i'm getting another Null pointer. I added WebDriver driver = new ChromeDriver(); but still getting error. Did I do it wrong? – user16626 Feb 27 '16 at 00:24
