Problem
1.If there is new version available
w.r.to browser then we must change it manually every time either chrome
driver/gecko/IE/Opera or any drivers.
Below is the example where we
explicitly specified path of drivers from folder.
Here if there is new chrome driver
then we must download then update that version under driver folder, same will
be applicable for gecko driver/IE drivers as well.
But there is way to avoid this by
using WebDriverManager.
WebDriver Manager is Abstract class
which has multiple methods to avoid specifying the driver paths.
WebDriverManager supports chromedriver
,firefoxdriver ,ie driver, edgedriver, operadriver… etc.
We have 2 ways to use WebDriverManager
1.
WebDriverManager.chromedriver().setup()
:-This will always tries to fetch the latest Chrome Driver version and download
it to local maven repo . m2/repository/webdriver
folder
Here WebDriverManager :
is Abstract Class
Chromedriver()
: is method for Chrome Browser, similarly we have firefoxdriver
iedriver for respective Firefox and IE Browsers
Setup() :
is method which will download the driver version into
WebDriverManager.firefoxdriver().setup();
WebDriverManager.iedriver().setup();
Code Below:
package automationTest;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.Assert;
import io.github.bonigarcia.wdm.WebDriverManager;
public class LoginLogout1 {
public static void main(String[] args) throws InterruptedException {
//System.setProperty("webdriver.chrome.driver","D:\\UPC\\Selenium\\Repository\\Project1\\drivers\\chromedriver1.exe");
WebDriverManager.chromedriver().setup();
WebDriver driver = new ChromeDriver();
driver.get("http://www.newtours.demoaut.com/");
System.out.println(driver.getTitle());
driver.findElement(By.xpath("//input[@name='userName']")).clear();
driver.findElement(By.xpath("//input[@name='userName']")).sendKeys("k.manjunath1818@gmail.com");
driver.findElement(By.xpath("//input[@name='password']")).clear();
driver.findElement(By.xpath("//input[@name='password']")).sendKeys("selenium@123");
driver.findElement(By.xpath("//input[@name='login']")).click();
Thread.sleep(10000);
driver.findElement(By.xpath("//tr//td[@class='mouseOut']//a[contains(text(),'SIGN-OFF')]")).click();
/*
* Assert.assertEquals(
* driver.findElement(By.xpath("//span[contains(text(),'India')]")) .getText(),
* "India");
*/
driver.close();
driver.quit();
}
}
2.WebDriverManager.chromedriver().version("83").setup() :-This will
tries to fetch the specified Chrome Driver version only.
Version() :- Will take
String arguments for version number
https://chromedriver.chromium.org/downloads --> For Chrome Driver Versions
When we are using any of these
methods, I would suggest to always cross check the Browser Version/Selenium
Version/Driver version because you may face compatibility issues and end with
with Session not Created Exception.
For Latest Chrome Browser u can use
below: -
Chrome Driver Version: - 83
Selenium Version: - 4
Browser Version: - Latest
code:
package automationTest;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.Assert;
import io.github.bonigarcia.wdm.WebDriverManager;
public class LoginLogout1 {
public static void main(String[] args) throws InterruptedException {
//System.setProperty("webdriver.chrome.driver","D:\\UPC\\Selenium\\Repository\\Project1\\drivers\\chromedriver1.exe");
WebDriverManager.chromedriver().version("83").setup();
WebDriver driver = new ChromeDriver();
driver.get("http://www.newtours.demoaut.com/");
System.out.println(driver.getTitle());
driver.findElement(By.xpath("//input[@name='userName']")).clear();
driver.findElement(By.xpath("//input[@name='userName']")).sendKeys("k.manjunath1818@gmail.com");
driver.findElement(By.xpath("//input[@name='password']")).clear();
driver.findElement(By.xpath("//input[@name='password']")).sendKeys("selenium@123");
driver.findElement(By.xpath("//input[@name='login']")).click();
Thread.sleep(10000);
driver.findElement(By.xpath("//tr//td[@class='mouseOut']//a[contains(text(),'SIGN-OFF')]")).click();
/*
* Assert.assertEquals(
* driver.findElement(By.xpath("//span[contains(text(),'India')]")) .getText(),
* "India");
*/
driver.close();
driver.quit();
}
}
If your using
Maven just add below Dependency: -
<!--
https://mvnrepository.com/artifact/io.github.bonigarcia/webdrivermanager -->
<dependency>
<groupId>io.github.bonigarcia</groupId>
<artifactId>webdrivermanager</artifactId>
<version>3.4.0</version>
</dependency>
If your using
Gradle just add below Dependency: -
//
https://mvnrepository.com/artifact/io.github.bonigarcia/webdrivermanager
compile group: 'io.github.bonigarcia',
name: 'webdrivermanager', version: '3.4.0'
If your using
Normal Java Project then download Jar from here and add to the Project: -
operatingSystem(OperatingSystem) :- By Default WebDriver
will try to download based on the user operating System but if we want to
explicitly specify the Operating system then this can be used. (
WIN, LINUX, MAC)
WebDriverManager.edgedriver().operatingSystem(OperatingSystem.MAC).setup();
browserVersion(String):- If we want to explicitly
specify the browser version for which we need the driver version then we can
specify that using this method
WebDriverManager.firefoxdriver().browserVersion("75").setup();
localRepositoryUser(String) / localRepositoryPassword(String) :- If we set username/Password for Local
repository then we can speciy the username/password with this so that when
WebDriverManager can access local repo even if its secured
Points to
Remember: -
1. Make sure to cross check the Browser/Selenium
with version number mentioned in Version(“”) method to compatibility Issues
2. WebDriverManager has 1 day ttl(time to live)
so once it downloaded the specified version or latest version till 24 hrs it
will look for local repo before launching browser if it doesn’t find then again
it will downloads (this can be configured using
3. With 4.x version of WebDriverManager few
methods are renamed refer the below link for complete Documentation
