Create WebDriver instance for multiple class in different ways

Hello friends,

In this article we will learn how to create WebDriver Instance multiple classes:

So, we will create a WebDriver instance in one class & call it in multiple class
we have achieve this by 2 ways
1).By using extends
2).By using Singleton class

Method :1By extends Keyword

Step :1Create a class & initialize your driver

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class MainDriver
{
public static WebDriver driver;
public static void createInstance()
{
System.setProperty("webdriver.chrome.driver", "D:\\Selenium\\Complete selenium\\ChromeDriver\\chromedriver.exe");
driver = new ChromeDriver();
driver.manage().window().maximize();
}
}

Step :2Create an another class & extend above driver class

public class Testcase1 extends MainDriver
{
public static void url()
{
MainDriver.createInstance();
driver.navigate().to("http://www.way2testing.com");
}
}

Step :3Create an another class & extend above driver class

public class TestCase2 extends MainDriver
{
public static void getTitle()
{
System.out.println(driver.getTitle());
}
}

Step :4Create an another class & extend above driver class

import org.testng.annotations.Test;

public class Excution
{
@Test(priority = 0)
public void getUrl()
{
Testcase1.url();
}
@Test(priority = 1)
public void getTitle()
{
TestCase2.getTitle();
}
}

If you will run this Exeution class , you can see that with one WebDriver Instance(driver), you are able to perform your all task.

Method :2By Singleton Class

Step :1Create a Singleton class & initialize your driver

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class SingletonDriver
{
public static WebDriver driver = null;
public static void Initiallize()
{
if(driver == null)
{
System.setProperty("webdriver.chrome.driver", "D:\\Selenium\\Complete selenium\\ChromeDriver\\chromedriver.exe");
driver = new ChromeDriver();
driver.manage().window().maximize();
}
}
public static void close()
{
driver.close();
}
public static void quit()
{
driver.quit();
}
}

Step :2Create a class for your test cases & execute singleclass method

import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;
public class Testcases
{
@BeforeTest
public void initializeDriver()
{
SingletonDriver.Initiallize();
}
@Test(priority = 0)
public void openurl()
{
SingletonDriver.driver.navigate().to("http://www.way2testing.com");
}
@Test(priority = 1)
public void getTitle()
{
System.out.println(SingletonDriver.driver.getTitle());
}
}

So, by using above methods, you can create a WebDriver Instanse(driver) and can use it in your multiple classes.
Thanks :)

Swap Two variable in Java

Hello friends,

In this article we will discuss about swap variable without using third variable:

For Video :- Click Here

public class Swap
{
int x = 10;
int y = 15;
public static void main(String args[])
{
Swap object = new Swap();
object.g();
}
public void g()
{
x = x+y;
y = x-y;
x = x-y;
System.out.println("After Swap Value of y : " + y);
System.out.println("After Swap Value of x : " + x);
}
}

output :
After Swap Value of y : 10
After Swap Value of x : 15

Code Explanation : Suppose we have two variable x, y and they have value 10, 15 respectively and we want to swap these two variables value.
HOW IT WOULD BE DONE ?
1). First , i will join these two variables value & store it in variable x.
Now the value of x is 25.
2). Now, we will minus the value of y(15) from this x(25).
we will get 10 & will store in variable y
3). Now the value on y is 10 & value of x is 25.
again we will minus this y value from & store it in variable x so value of variable of x will become 15.

Congratulation You have swapped the value of two variable without using third variable. :)

1. Write a program to swap two string without using any third string/variable

Answer :- First add both the string and store in a existing variable then use String method Substring to get the string


Below is program

public class PracticeA {

public static void main(String args[]) {

String x = "chandan";
String y = "singh";

System.out.println("Value of x: " +x + " , " + "Value of y :" + y + " ," +"before swapping");
x = x+y;

y = x.substring(0, x.length()-y.length());

x = x.substring(y.length());
System.out.println("Value of x: " +x + " , " + "Value of y :" + y + " ," +"after swapping");
}
}

Output :- Value of x: chandan, Value of y :singh ,before swapping Value of x: singh, Value of y :chandan ,after swapping
