# Overview #

ChromeDriver and Selenium are tools for automated testing of Chromium-based applications. The tests themselves can be written in a number of languages including Java, JavaScript and Python. ChromeDriver communicates with the Chromium-based application using the DevTools remote debugging protocol (configured via the --remote-debugging-port=XXXX command-line flag passed to the application). Detailed ChromeDriver/Selenium usage information is available here:

# Java Tutorial #

This tutorial demonstrates how to control the cefclient sample application using the Java programming language on Windows. Usage on other platforms and with other CEF-based applications is substantially similar.

1.  Install the Java JDK and add its bin directory to your system PATH variable.
2.  Create a directory that will contain all files. This tutorial uses c:\\temp.
3.  Download ChromeDriver from [https://sites.google.com/a/chromium.org/chromedriver/downloads][https_sites.google.com_a_chromium.org_chromedriver_downloads] and extract (e.g. chromedriver\_win32.zip provides chomedriver.exe). This tutorial was tested with version 2.14.
4.  Download selenium-server-standalone-x.y.z.jar from [http://selenium-release.storage.googleapis.com/index.html][http_selenium-release.storage.googleapis.com_index.html]. This tutorial was tested with version 2.44.0.
5.  Download a CEF binary distribution client from Downloads and extract (e.g. cef\_binary\_3.2171.1979\_windows32\_client.7z).
6.  Create Example.java:

import org.openqa.selenium.By;
    import org.openqa.selenium.WebDriver;
    import org.openqa.selenium.WebElement;
    import org.openqa.selenium.chrome.ChromeDriver;
    import org.openqa.selenium.chrome.ChromeOptions;
    
    public class Example  {
      public static void main(String[] args) {
        // Path to the ChromeDriver executable.
        System.setProperty("webdriver.chrome.driver", "c:/temp/chromedriver.exe");
    
        ChromeOptions options = new ChromeOptions();
        // Path to the CEF executable.
        options.setBinary("c:/temp/cef_binary_3.2171.1979_windows32_client/Release/cefclient.exe");
        // Port to communicate on. Required starting with ChromeDriver v2.41.
        options.addArguments("remote-debugging-port=12345");
    
        WebDriver driver = new ChromeDriver(options);
        driver.get("http://www.google.com/xhtml");
        sleep(3000);  // Let the user actually see something!
        WebElement searchBox = driver.findElement(By.name("q"));
        searchBox.sendKeys("ChromeDriver");
        searchBox.submit();
        sleep(3000);  // Let the user actually see something!
        driver.quit();
      }
    
      static void sleep(int time) {
        try { Thread.sleep(time); } catch (InterruptedException e) {}
      }
    }

Your directory structure should now look similar to this:

c:\temp\
      cef_binary_3.2171.1979_windows32_client\
        Release\
          cefclient.exe  (and other files)
      chromedriver.exe
      Example.java
      selenium-server-standalone-2.44.0.jar

1.  Compile Example.java to generate Example.class:

> cd c:\temp
    > javac -cp ".;*" Example.java

1.  Run the example:

> cd c:\temp
    > java -cp ".;*" Example
    When the example is run ChromeDriver will:

Output to the console:

Starting ChromeDriver 2.14.313457 (3d645c400edf2e2c500566c9aa096063e707c9cf) on port 28110
    Only local connections are allowed.

Launch cefclient.exe.  
Submit a Google search for "ChromeDriver".  
Close cefclient.exe.
