webdrivermanager

WebDriverManager is an open-source Java library that 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. In addition, WebDriverManager provides other relevant features, such as the capability to discover browsers installed in the local system, building WebDriver objects (such as ChromeDriver, FirefoxDriver, EdgeDriver, etc.), and running browsers in Docker containers seamlessly.

Documentation

As of version 5, the documentation of WebDriverManager has moved here. This site contains all the features, examples, configuration, and advanced capabilities of WebDriverManager.

Driver Management

The primary use of WebDriverManager is the automation of driver management. For using this feature, you need to select a given manager in the WebDriverManager API (e.g., chromedriver() for Chrome) and invoke the method setup(). The following example shows the skeleton of a test case using JUnit 5, Selenium WebDriver, and WebDriverManager.

import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeAll;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

import io.github.bonigarcia.wdm.WebDriverManager;

class ChromeTest {

    WebDriver driver;

    @BeforeAll
    static void setupAll() {
        WebDriverManager.chromedriver().setup();
    }

    @BeforeEach
    void setup() {
        driver = new ChromeDriver();
    }

    @AfterEach
    void teardown() {
        driver.quit();
    }

    @Test
    void test() {
        // Your test logic here
    }

}

Alternatively, you can use the method create() to manage automatically the driver and instantiate the WebDriver object in a single line. For instance, as follows:

import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

import io.github.bonigarcia.wdm.WebDriverManager;

class ChromeCreateTest {

    WebDriver driver;

    @BeforeEach
    void setup() {
        driver = WebDriverManager.chromedriver().create();
    }

    @AfterEach
    void teardown() {
        driver.quit();
    }

    @Test
    void test() {
        // Your test logic here
    }

}

For further information about the driver resolution algorithm implemented by WebDriverManager and configuration capabilities, read the documentation.

Browsers in Docker

Another relevant new feature available in WebDriverManager 5 is the ability to create browsers in Docker containers out of the box. The requirement to use this feature is to have installed a Docker Engine in the machine running the tests. To use it, we need to invoke the method browserInDocker() in conjunction with create() of a given manager. This way, WebDriverManager pulls the image from Docker Hub, starts the container, and instantiates the WebDriver object to use it. The following test shows a simple example using Chrome in Docker. This example also enables the recording of the browser session and remote access using noVNC:

import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.openqa.selenium.WebDriver;

import io.github.bonigarcia.wdm.WebDriverManager;

class DockerChromeVncTest {

    WebDriver driver;

    WebDriverManager wdm = WebDriverManager.chromedriver().browserInDocker()
            .enableVnc().enableRecording();

    @BeforeEach
    void setup() {
        driver = wdm.create();
    }

    @AfterEach
    void teardown() {
        wdm.quit();
    }

    @Test
    void test() {
        // Your test logic here
    }

}

Support

WebDriverManager is part of OpenCollective, an online funding platform for open and transparent communities. You can support the project by contributing as a backer (i.e., a personal donation or recurring contribution) or as a sponsor (i.e., a recurring contribution by a company).
