  • Automation of web driver | Usage of WebDriverManager or alternative for System.setProperty("webdriver.chrome.driver", "D\chromedriver.exe");


    • WebDriverManager is an open-source Java library
    • It carries out the management (i.e., download, setup, and maintenance) of the drivers required by Selenium WebDriver(e.g., chromedriver, geckodriver, msedgedriver, etc.) in a fully automated manner.
    • The primary use of WebDriverManager is the automation of driver.
    • With this we can get rid of System property to fetch the driver placed in physical drive or from the project path.

    Example: 
    This is how we set the path for chrome driver once the driver is downloaded and placed in system hard drive . 
    System.setProperty("webdriver.chrome.driver", "D\chromedriver.exe");

    Now, using DriverMnager we can get rid of physical drive path, that is replace the above line of code with 
    WebDriverManager.chromedriver().setup();

    This requires the following dependency to be added in pom.xml file. 

    <!-- https://mvnrepository.com/artifact/io.github.bonigarcia/webdrivermanager --><dependency><groupId>io.github.bonigarcia</groupId><artifactId>webdrivermanager</artifactId><version>4.3.0</version></dependency>

    In the Before hook of cucumber, normally we create the ChromeDriver object, prior creating the chrome driver object, we need to call the chrome driver setup() as shown in below example.

    @Before(order = 0) // Cucumber Before Hook with order 0public void before(Scenario scenario) throws IOException {	Log.info("Initiating the chrome driver from Cucumber Before hook with order=0");			WebDriverManager.chromedriver().setup();	driver = new ChromeDriver();	driver.manage().window().maximize();}
