Ways of passing Driver to other class

There are different way with which you can pass the driver in other class. Below are those 3 ways.

1. By passing driver as parameter in class object
2.By returning the driver
3.By inheritance using super for driver

1st method is- 

By passing driver as parameter in class object

In this method, we will pass driver as parameter in other class.

public class PageFactory_OtherClass {

WebDriver driver;
 @BeforeMethod
 public void beformethods()   //In this call driver is initiated.
 {
  System.setProperty("webdriver.chrome.driver", "C:\\ChromeDriver\\chromedriver_78.exe");
  driver= new ChromeDriver();
  driver.get("https://google.com");
 }
 @Test
 public void launchBrowser()
 {
  SubClass sb= new SubClass(driver);// here we are passing driver as parameter in other class
  sb.enterSearchText();
 }
}
public class SubClass  {
 WebDriver driver=null;
 @FindBy (xpath="//input[@title='Search']")
 WebElement search;
 public SubClass(WebDriver driver)
 {
 this.driver=driver; 
  PageFactory.initElements(driver, this);
 }
 public void enterSearchText()
 {
  search.sendKeys("new search");
 }
}



 

2nd method is- 

By returning the driver

In this method, we will return driver and use in other classes.

public class SubClass1 {
 static WebDriver driver;
 
 public WebDriver driver() // This method return the driver
 {
  System.setProperty("webdriver.chrome.driver", "C:\\ChromeDriver\\chromedriver_78.exe");
  driver= new ChromeDriver();
  this.driver=driver; 
  return driver;
 } 
}
public class SubClass   {

 static WebDriver driver;
 @FindBy (xpath="//input[@title='Search']")
 WebElement search;
 
 public SubClass()
 {
  SubClass1 subc=new SubClass1();
  driver=subc.driver();               //here you use the above driver
  this.driver=driver;
  PageFactory.initElements(driver, this);
 }
 
 public void enterSearchText()
 {
  driver.get("https://google.com");
  search.sendKeys("new search");
  driver.manage().window().maximize();
 }
 
 }

public class PageFactory_OtherClass {
  
 WebDriver driver;
 SubClass sb;
  
 @BeforeMethod
 public void beformethods()
 {
  sb= new SubClass();
 }
 @Test
 public void launchBrowser()
 {
 
  sb.enterSearchText();
 }
}

3rd method is- 

By inheritance using super for driver

This method, we will inherit the driver from supper class.

public class SubClass1 {      // this is super class where driver is initiated.
 static WebDriver driver;
 public SubClass1(WebDriver driver)
 {
  System.setProperty("webdriver.chrome.driver", "C:\\ChromeDriver\\chromedriver_78.exe");
  driver= new ChromeDriver();
  this.driver=driver; 
 }
}

public class SubClass extends SubClass1  {     //super class inherited here

 @FindBy (xpath="//input[@title='Search']")
 WebElement search;
 public SubClass()
 {
  super(driver);                             //here we call the driver of super class
  PageFactory.initElements(driver, this);
 }
 public void enterSearchText()
 {
  driver.get("https://google.com");
  search.sendKeys("new search");
  driver.manage().window().maximize();
 }
}

public class PageFactory_OtherClass {
  
 WebDriver driver;
 SubClass sb;
  
 @BeforeMethod
 public void beformethods()
 {
  sb= new SubClass();
 }
 @Test
 public void launchBrowser()
 {
 
  sb.enterSearchText();
 }
