I am using a firefox driver and I notice that because I initialize a new instance of the firefox Driver, I have two fireFox windows open when my test runs. Is there a correct way in terms of initialising the driver as I may be wrong but I am guessing I shouldn't be writing WebDriver webDriver = new FirefoxDriver(); in two locations and somehow write it within one location only and call on it?
Page 1:
public class waitMethods extends PageObject {
WebDriver webDriver = new FirefoxDriver();
public void waitForElementToBeDisplayed(By element){
try {
WebDriverWait webDriverWait = new WebDriverWait(webDriver, 30);
webDriverWait.until(ExpectedConditions.presenceOfElementLocated(element));
System.out.println(element + " is displayed correctly");
} catch (Exception e) {
e.printStackTrace();
Assert.fail();
System.out.println(element + " is not displayed");
}
}
Page 2:
public class WebPageMethods extends PageObject {
WebDriver webDriver = new FirefoxDriver();
public void navigateToAuth0WebPage(){
webDriver.get("https://www.test.com");
}
There is an example, how to inherit from WebDriver:
WebDriver setup class:
package brucey;

public class WebDriverSetup {
public static WebDriver driver;
public static String driverPath = "C:\\Users\\pburgr\\Desktop\\selenium-tests\\FF_driver_0_23\\geckodriver.exe";
public static WebDriver startFF() {
FirefoxOptions options = new FirefoxOptions();
ProfilesIni allProfiles = new ProfilesIni();
FirefoxProfile selenium_profile = allProfiles.getProfile("selenium_profile");
options.setProfile(selenium_profile);
options.setBinary("C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe");
System.setProperty("webdriver.gecko.driver", driverPath);
driver = new FirefoxDriver(options);
driver.manage().window().maximize();
return driver;
}
public static void shutdownFF() {
driver.quit();
}
}

In above code TestNG passing only one Test named as Login(). Can anyone tell me please why is it so?
How to improve this code and run all tests in a series.
When I run your code, I get the following log:
PASSED: login
FAILED: PayGrade
org.testng.TestNGException:
Cannot inject #Test annotated Method [PayGrade] with [interface org.openqa.selenium.WebElement].
For more information on native dependency injection please refer to https://testng.org/doc/documentation-main.html#native-dependency-injection
I do not think put WebElement job as parameter of PayGrade(WebElement job) is right, so try to fix this kind of codes.

I am creating page object model plus data driver framework.
I am writing Testcase for logIn but getting pagefactory nullpointerexception.
1. How I can initialise my driver in order to avoid this error?
2. Again How I can Sccreenshot page class in my test script i have given code below.

ImageIO.write(fpScreenshot.getImage(), "PNG", new File("D:/selenium/" + System.currentTimeMillis() + ".png"));
}
}
Make this method to return WebDriver :
public WebDriver initialize() throws InterruptedException, IOException {
System.out.println("Launching browser");
System.setProperty("webdriver.chrome.driver",
"C:\\Users\\admin\\eclipse-workspace\\SampleProject\\src\\main\\java\\selenium\\org\\sample\\SampleProject\\data\\chromedriver.exe");

driver.navigate().to("http://automationpractice.com/index.php?controller=authentication&back=my-account");
Thread.sleep(6000);
return driver;
}
and in AppTest class use it as :
public class AppTest extends ExcelReader {
public WebDriver driver;
TestBase TB = new TestBase();
#BeforeTest
void browserlaunch() throws InterruptedException, IOException
{
driver = TB.initialize();
}
For screenshot make your method as :
public static void ScreenshotPage1(WebDriver driver) throws InterruptedException, IOException {
Screenshot fpScreenshot = new AShot().shootingStrategy(ShootingStrategies.viewportPasting(1000))
.takeScreenshot(driver);
ImageIO.write(fpScreenshot.getImage(), "PNG", new File("D:/selenium/" + System.currentTimeMillis() + ".png"));
}
and after #Test use in AppTest class :
#AfterMethod
public void takeScreenShot() throws InterruptedException, IOException {
ScreenshotPage.ScreenshotPage1(driver);

First of all You have duplicated #FindBy(id = "email_input").
public class loginpage should have constructor when initialization is called with new loginpage();
PageFactory.initElements(driver, this);
so when You do loginpage login = new loginpage(); it doesn't initialize Your PageFactory, because You've made it an method not constructor.
So try like this
public LoginPage(WebDriver webDriver) {
super(webDriver); //this is if You extend driver from super-class
PageFactory.initElements(webDriver, this);
}
But just add code into constructor under pagelogin class.
Hope this is helpful.
