WebDriverManager in Selenium

Before we begin, Let’s understand what is WebDriverManager ?

WebDriverManager is a Java Library that helps in driver management required for Selenium.

It carries out driver management actions such as download, setup & maintenance.

It is a open-source Library supports for drivers like, chromedriver (Chrome Browser) , geckodriver ( for Firefox Browser) ,msedgedriver ( for Edge Browser), etc.

Setup

We Typically use 2 types of build management tools for Selenium project i.e. Maven & Gradle.

To download WebDriverManager dependencies for a Build, we need to include below line of code into the build file.

• Maven

<dependency>
 <groupId>io.github.bonigarcia</groupId>
 <artifactId>webdrivermanager</artifactId>
 <version>5.1.1</version>
</dependency>

• Gradle

implementation group: ‘io.github.bonigarcia’, name: ‘webdrivermanager’, version: ‘5.1.1’

Latest version can be checked from, https://mvnrepository.com/artifact/io.github.bonigarcia/webdrivermanager

• you may also include .jar file for webdrivermanager to the project, Just in case if you are not familiar with the build tools.

How to instantiate Browser using WebDriverManager ?

we need to add below line of code to test, (this will set the chrome driver for the test). It has Automated way to download the required Binaries/.exe files.

Below line will check the latest version of specified driver binary is available on the machine or node. If it’s not present then it will download it.

WebDriverManager.chromedriver().setup();

Once you have downloaded the required binary(.exe) file for driver. we need to create the Object of specific browser using below line of code.

WebDriver driver = new ChromeDriver();

Above line will instantiate the Selenium Webdriver instance to the ChromeDriver.

Example:

Below line of code is simple example of how to use WebDriverManager in Tests.

In the above code,

1. We have imported required classes using import statements.
2. Created a WebDriverManager instance using WebDriveManager.chromedriver.setup();
3. Created driver instance for chromedriver
4. Navigated to https://www.google.com using driver.get() method.
5. At the end, quit the driver instance.
