JarCastingWe forked this project to add "get drivers from Nexus" functionality and use it with Page-Factory framework.
WebDriverManager 
This library is aimed to automate the Selenium Webdriver binaries management in runtime for Java.
If you are using Selenium Webdriver, you would know that to use some browsers such as Chrome, Firefox, Opera, PhantomJS, Microsoft Edge, or Internet Explorer, you need to download a binary which allows WebDriver to handle the browser. In addition, the absolute path to this binary must be set as JVM properties, as follows:
System.setProperty("webdriver.chrome.driver", "/absolute/path/to/binary/chromedriver");
System.setProperty("webdriver.gecko.driver", "/absolute/path/to/binary/geckodriver");
System.setProperty("webdriver.opera.driver", "/absolute/path/to/binary/operadriver");
System.setProperty("phantomjs.binary.path", "/absolute/path/to/binary/phantomjs");
System.setProperty("webdriver.edge.driver", "C:/absolute/path/to/binary/MicrosoftWebDriver.exe");
System.setProperty("webdriver.ie.driver", "C:/absolute/path/to/binary/IEDriverServer.exe");
This is quite annoying since it forces you to link directly this binary in your source code. In addition, you have to check manually when new versions of the binaries are released. WebDriverManager comes to the rescue, performing in an automated way all this dirty job for you.
WebDriverManager is open source, released under the terms of Apache 2.0 License.
Usage
In order to use WebDriverManager in a Maven project, first add the following dependency to your pom.xml (Java 7 or upper required):
<dependency>
<groupId>ru.sbtqa</groupId>
<artifactId>webdrivermanager</artifactId>
<version>2.2.2</version>
</dependency>
WebDriverManager is typically used by tests, and therefore, the typical scope would be test (<scope>test</scope>).
Once we have included this dependency, you can let WebDriverManager to manage the WebDriver binaries for you. Take a look at this JUnit 4 example which uses Chrome with Selenium WebDriver (in order to use WebDriverManager in conjunction with JUnit 5, the extension selenium-jupiter is highly recommended):
public class ChromeTest {
private WebDriver driver;
@BeforeClass
public static void setupClass() {
ChromeDriverManager.getInstance().setup();
}
@Before
public void setupTest() {
driver = new ChromeDriver();
}
@After
public void teardown() {
if (driver != null) {
driver.quit();
}
}
@Test
public void test() {
// Your test code here
}
}
Notice that simply adding ChromeDriverManager.getInstance().setup(); WebDriverManager does magic for you:
- It checks for the latest version of the WebDriver binary.
- It downloads the WebDriver binary if it's not present on your system.
- It exports the required WebDriver Java environment variables needed by Selenium.
So far, WebDriverManager supports Chrome, Firefox, Opera, PhantomJS, Microsoft Edge, and Internet Explorer. For that, it provides several drivers managers for these browsers, i.e. ChromeDriverManager, FirefoxDriverManager, OperaDriverManager, PhantomJsDriverManager, EdgeDriverManager, and InternetExplorerDriverManager. These drivers managers can be used as follows:
ChromeDriverManager.getInstance().setup();
FirefoxDriverManager.getInstance().setup();
OperaDriverManager.getInstance().setup();
PhantomJsDriverManager.getInstance().setup();
EdgeDriverManager.getInstance().setup();
InternetExplorerDriverManager.getInstance().setup();
Moreover, WebDriverManager provides a generic driver manager called WebDriverManager. This manager which can be parameterized using Selenium driver classes (e.g. org.openqa.selenium.chrome.ChromeDriver, org.openqa.selenium.firefox.FirefoxDriver, etc), as follows:
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import io.github.bonigarcia.wdm.WebDriverManager;
// ...
Class<? extends WebDriver> driverClass = ChromeDriver.class;
WebDriverManager.getInstance(driverClass).setup();
WebDriver driver = driverClass.newInstance();

WebDriverManager API
WebDriverManager exposes its API by means of the builder pattern. This means that given a DriverManger instance (e.g. ChromeDriverManager, FirefoxDriverManager, and so on), their capabilities can be tuned using different methods. The following table summarizes the WebDriverManager API, together with the equivalent configuration key:
| Method | Description | Equivalent configuration key |
|---|---|---|
version() |
By default, WebDriverManager tries to download the latest version of a given driver binary. A concrete version can be specified using this method. | wdm.chromeDriverVersion, wdm.operaDriverVersion, wdm.internetExplorerVersion, wdm.edgeVersion, wdm.phantomjsDriverVersion, wdm.geckoDriverVersion |
forceCache() |
By default, WebDriverManager connects to the specific driver repository URL to find out what is the latest version of the binary. This can be avoided forcing to use the latest version form the local repository. | wdm.forceCache=true |
forceOperativeSystem(OperativeSystem operativeSystem) |
By default, WebDriverManager downloads the binary for the same operative systems than the machine running the test. This can be changed using this method (accepted values: WIN, LINUX, MAC). |
wdm.forceOs=WIN, wdm.forceOs=LINUX, wdm.forceOs=MAC |
forceDownload() |
By default, WebDriverManager finds out the latest version of the binary, and then it uses the cached version if exists. This option forces to download again the binary even if it has been previously cached. | wdm.override=true |
useBetaVersions() |
By default, WebDriverManager skip beta versions. With this method, WebDriverManager will download also beta versions. | wdm.useBetaVersions=true |
architecture(Architecture arch) |
By default, WebDriverManager would try to use the proper binary for the platform running the test case (i.e. 32-bit or 64-bit). This behavior can be changed by forcing a given architecture: 32-bits (Architecture.x32) or 64-bits (Architecture.x64); |
wdm.architecture |
arch32() |
Force to use the 32-bit version of a given driver binary. | wdm.architecture=32 |
arch64() |
Force to use the 64-bit version of a given driver binary. | wdm.architecture=64 |
driverRepositoryUrl(URL url) |
This method allows to change the repository URL in which the binaries are hosted (see next section for default values). | wdm.chromeDriverUrl, wdm.operaDriverUrl, wdm.internetExplorerDriverUrl, wdm.edgeDriverUrl, wdm.phantomjsDriverUrl, wdm.geckoDriverUrl |
useTaobaoMirror() |
The npm.taobao.org site is a mirror which hosts different software assets. Among them, it hosts chromedriver, geckodriver, operadriver, and phantomjs driver. Therefore, this method can be used in ChromeDriverManager, FirefoxDriverManager, OperaDriverManager, and PhantomJsDriverManager to force to use the taobao.org mirror. |
wdm.useTaobaoMirror=true |
useNexus(String nexusUrl) |
This method can be used in ChromeDriverManager, FirefoxDriverManager, OperaDriverManager, and PhantomJsDriverManager to force to use your Nexus instead of default repos. |
|
proxy(String proxy) |
Use a HTTP proxy for the Internet connection. | wdm.proxy |
proxyUser(String username) |
Specify a username for HTTP proxy. | wdm.proxyUser |
proxyPass(String password) |
Specify a password for HTTP proxy. | wdm.proxyPass |
The following table contains some examples:
| Example | Description |
|---|---|
ChromeDriverManager.getInstance().version("2.26").setup(); |
Force to use version 2.26 of chromedriver |
FirefoxDriverManager.getInstance().arch32().setup(); |
Force to use the 32-bit version of geckodriver |
OperaDriverManager.getInstance().forceCache().setup(); |
Force to use the cache version of operadriver |
PhantomJsDriverManager.getInstance().useTaobaoMirror().setup(); |
Force to use the taobao.org mirror to download phantomjs driver |
ChromeDriverManager.getInstance().proxy("server:port").setup(); |
Using proxy server:port for the connection |
ChromeDriverManager.getInstance().useNexus("myNexusUrl").setup(); |
Force to use the Nexus to download chrome driver |
Configuration
Configuration parameters for WebDriverManager are set in the webdrivermanager.properties file (you can't manage Nexus parameters by properties file yet):
wdm.targetPath=~/.m2/repository/webdriver
wdm.forceCache=false
wdm.override=false
wdm.useBetaVersions=false
wdm.timeout=30
wdm.chromeDriverUrl=https://chromedriver.storage.googleapis.com/
wdm.chromeDriverTaobaoUrl=http://npm.taobao.org/mirrors/chromedriver
wdm.chromeDriverExport=webdriver.chrome.driver
wdm.chromeDriverVersion=LATEST
wdm.operaDriverUrl=https://api.github.com/repos/operasoftware/operachromiumdriver/releases
wdm.operaDriverTaobaoUrl=http://npm.taobao.org/mirrors/operadriver
wdm.operaDriverExport=webdriver.opera.driver
wdm.operaDriverVersion=LATEST
wdm.internetExplorerDriverUrl=https://selenium-release.storage.googleapis.com/
wdm.internetExplorerExport=webdriver.ie.driver
wdm.internetExplorerVersion=LATEST
wdm.edgeDriverUrl=https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/
wdm.edgeExport=webdriver.edge.driver
wdm.edgeVersion=LATEST
wdm.phantomjsDriverUrl=https://bitbucket.org/ariya/phantomjs/downloads/
wdm.phantomjsDriverTaobaoUrl=http://npm.taobao.org/mirrors/phantomjs
wdm.phantomjsDriverExport=phantomjs.binary.path
wdm.phantomjsDriverVersion=LATEST
wdm.geckoDriverUrl=https://api.github.com/repos/mozilla/geckodriver/releases
wdm.geckoDriverTaobaoUrl=http://npm.taobao.org/mirrors/geckodriver
wdm.geckoDriverExport=webdriver.gecko.driver
wdm.geckoDriverVersion=LATEST
The variable wdm.targetPath is the default folder in which WebDriver binaries are going to be stored. Notice that by default the path of the Maven local repository is used. The URLs to check the latest version of Chrome, Opera, Internet Explorer, Edge, PhantomJS, and Firefox are set using the variables wdm.chromeDriverUrl, wdm.operaDriverExport, wdm.operaDriverUrl, wdm.edgeDriverUrl, wdm.phantomjsDriverUrl, and wdm.geckoDriverUrl.
These properties can be overwritten by Java system properties, for example:
System.setProperty("wdm.targetPath", "/my/custom/path/to/driver/binaries");
... or by command line, for example:
-Dwdm.override=true
By default, WebDriverManager downloads the latest version of the WebDriver binary. But concrete versions of WebDriver binaries can be forced by changing the value of the variables wdm.chromeDriverVersion, wdm.operaDriverVersion, wdm.internetExplorerVersion, or wdm.edgeVersion from its default value (LATEST) to a concrete version. For instance:
-Dwdm.chromeDriverVersion=2.25
-Dwdm.internetExplorerVersion=2.46
-Dwdm.operaDriverVersion=0.2.0
-Dwdm.edgeVersion=3.14366
-Dwdm.phantomjsDriverVersion=2.1.1
-Dwdm.geckoDriverVersion=0.11.1
If no version is specified, WebDriverManager sends a request to the server hosting the binary. In order to avoid this request and check if any binary has been previously downloaded, the key wdm.forceCache can be used.
As of WebDriverManager 2, the value of these properties can be overridden by means of environmental variables. The name of these variables result from putting the name in uppercase and replacing the symbol . by _. For example, the property wdm.targetPath can be overridden by the environment variable WDM_TARGETPATH.
HTTP Proxy
If you use an HTTP Proxy in your Internet connection, you can configure your settings by exporting the Java environment variable HTTPS_PROXY using the following notation: my.http.proxy:1234 or username:[email protected]:1234. Also you can configure username and password using environment variables (HTTPS_PROXY_USER and HTTPS_PROXY_PASS).
Known Issues
Some of the binaries (for Opera and Firefox) are hosted on GitHub. When several consecutive requests are made by WebDriverManager, GitHub servers return an HTTP 403 error response as follows:
Caused by: java.io.IOException: Server returned HTTP response code: 403 for URL: https://api.github.com/repos/operasoftware/operachromiumdriver/releases

In order to avoid this problem, authenticated requests should be done. The procedure is the following:
- Create a token/secret pair in your GitHub account
- Tell WebDriverManager the value of this pair token/secret. To do that you should use the configuration keys
wdm.gitHubTokenNameandwdm.gitHubTokenSecret. You can pass them as command line Java parameters as follows:
-Dwdm.gitHubTokenName=<your-token-name>
-Dwdm.gitHubTokenSecret=<your-token-secret>
