How to use addPreference method of org.openqa.selenium.firefox.FirefoxOptions class

Simplest solution would be to create seperate objects for FF and Chrome. Modify get method to take a parameter(browserType) and then return the correspoding object.

Why are you switching browsers?

Unfortunately Selenium WebDriver 2.53.0 is not compatible with Firefox 47.0. The WebDriver component which handles Firefox browsers (FirefoxDriver) will be discontinued. As of version 3.0, Selenium WebDriver will need the geckodriver binary to manage Firefox browsers. More info here and here.

Therefore, in order to use Firefox 47.0 as browser with Selenium WebDriver 2.53.0, you need to download the Firefox driver (which is a binary file called geckodriver as of version 0.8.0, and formerly wires) and export its absolute path to the variable webdriver.gecko.driver as a system property in your Java code:

System.setProperty("webdriver.gecko.driver", "/path/to/geckodriver");

Luckily, the library WebDriverManager can do this work for you, i.e. download the proper Marionette binary for your machine (Linux, Mac, or Windows) and export the value of the proper system property. To use this library, you need to include this dependency into your project:

<dependency>
    <groupId>io.github.bonigarcia</groupId>
    <artifactId>webdrivermanager</artifactId>
    <version>5.1.0</version>
</dependency>

... and then execute this line in your program before using WebDriver:

WebDriverManager.firefoxdriver().setup();

A complete running example of a JUnit 4 test case using WebDriver could be as follows:

public class FirefoxTest {

    protected WebDriver driver;

    @BeforeClass
    public static void setupClass() {
        WebDriverManager.firefoxdriver().setup();
    }

    @Before
    public void setupTest() {
        driver = new FirefoxDriver();
    }

    @After
    public void teardown() {
        if (driver != null) {
            driver.quit();
        }
    }

    @Test
    public void test() {
        // Your test code here
    }
}

Take into account that Marionette will be the only option for future (for WebDriver 3+ and Firefox 48+), but currently (version 0.9.0 at writing time) is not very stable. Take a look to the Marionette roadmap for further details.

UPDATE

Selenium WebDriver 2.53.1 has been released on 30th June 2016. FirefoxDriver is working again with Firefox 47.0.1 as browser.

Problems with solution mentioned before :-

All solutions answered to record video, records test execution from start to end. If automation suite run for hours then this won't be practical and optimal solution.

Main purpose of record video is to SEE what exactly happened when automation test case failed. So precisely testers need video recording of LAST 15 SECONDS BEFORE TEST CASE FAILED. They don't need any recording for PASSED test cases

Solution in theory :-

On Windows 10 onwards, Windows Xbox Game bar [Windows+G] has ability to capture LAST 15 seconds [customizable] of video. Keyboard shortcut Windows+Alt+G is use to capture last 15 seconds of video using XBox Game Bar and it would be stored in folder mentioned in settings.

Selenium automation can exploit this recording feature of Windows Xbox Game bar. In your testNG automation project, in onTestFailure method of testNG listener just add code to keypress Windows+Alt+G to capture last 15 seconds video. This would capture video for ONLY failed test cases and never for PASS test cases. If you are using Java then you can use Robot library to send keypress programatically.

Screenshots showing Windows XBox game Bar and it's setting to capture last 15 seconds.

Solution in Code :-

I am calling below recordFailedTCVideo() method from testNG listner's
public void onTestFailure(ITestResult result) method. This will just record last 15 seconds of video ONLY for failed test cases.[and not for PASS test cases]

Video explanation :- https://www.youtube.com/watch?v=p6tJ1fVaRxw

public void recordFailedTCVideo(ITestResult result) {
    //private void pressKey() {
    System.out.println("In recordFailedTCVideo::***In Try Block *** Video for test case failed " + result.getName());
    commonUtility.logger.error("BaseTest::recordFailedTCVideo::***In Try Block ***  Video for test case failed " + result.getName());
    
        try {
            // Useing Robot class to keypres Win+Alt+G which will capture last 15 seconds of video
            Robot r = new Robot();
            r.keyPress(KeyEvent.VK_WINDOWS );
            Thread.sleep(1000);
            r.keyPress(KeyEvent.VK_ALT );
            Thread.sleep(1000);
            r.keyPress(KeyEvent.VK_G );
            Thread.sleep(5000);
            
            r.keyRelease(KeyEvent.VK_WINDOWS);
            Thread.sleep(1000);
            r.keyRelease(KeyEvent.VK_ALT);
            Thread.sleep(1000);
            r.keyRelease(KeyEvent.VK_G);
            Thread.sleep(5000);
          
            /// Copy Video saved to desired location
            
            File srcDir = new File(commonUtility.prop.getProperty("VIDEO_CAPTURE_DEFAULT_LOCATION"));

            DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyyMMdd HHmmss");  
            LocalDateTime now = LocalDateTime.now();  
          
            String destination = ".\\ScreenshotsAndVideos\\" + dtf.format(now) ;
            File destDir = new File(destination);

            try {
                System.out.println("In RecordFailedTCVideo::Source Folder is "+ srcDir +" Destination Folder = " + destDir);
                commonUtility.logger.error("In RecordFailedTCVideo::Source Folder is "+ srcDir +" Destination Folder = " + destDir);

                FileUtils.moveDirectory(srcDir, destDir);
                
            } catch (IOException e) {
                e.printStackTrace();
            }
                    
        } catch (Exception e) {
            System.out.println("In recordFailedTCVideo::***In Catch Block ***\n" +e);
            commonUtility.logger.error("BaseTest::recordFailedTCVideo::***In Catch Block *** \n"+e );
            
            e.printStackTrace();
        }
    //}
}

Constraints :-

This solution is not for non-Windows platforms. XBar Game utility would not record Windows Explorer , text files etc. Although it records browsers without problem.

I met the same issue. cucumber-java 1.2.2 is working for me.

<dependency>
    <groupId>info.cukes</groupId>
    <artifactId>cucumber-java</artifactId>
    <version>1.2.2</version>
</dependency>

Scenario/Test steps:
1. Open a browser and navigate to TestURL
2. Scroll down some pixel and scroll up

For Scroll down:

WebDriver driver = new FirefoxDriver();
JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("window.scrollBy(0,250)");

OR, you can do as follows:

jse.executeScript("scroll(0, 250);");

For Scroll up:

jse.executeScript("window.scrollBy(0,-250)");
OR,
jse.executeScript("scroll(0, -250);");

Scroll to the bottom of the page:

Scenario/Test steps:
1. Open a browser and navigate to TestURL
2. Scroll to the bottom of the page

Way 1: By using JavaScriptExecutor

jse.executeScript("window.scrollTo(0, document.body.scrollHeight)");

Way 2: By pressing ctrl+end

driver.findElement(By.cssSelector("body")).sendKeys(Keys.CONTROL, Keys.END);

Way 3: By using Java Robot class

Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_END);
robot.keyRelease(KeyEvent.VK_END);
robot.keyRelease(KeyEvent.VK_CONTROL);

I had an extra ":" in my feature file after Given, When and Then.

It's working now.

The typical solution to this is a try/catch against a wait. E.g. if the next step is to click a button that shows once loading completes:

    WebDriverWait wait = new WebDriverWait(driver, LOADING_TIMEOUT);

    WebElement webElement;
    try {
        webElement = wait.until(elementToBeClickable(By.id(id)));
    } catch (TimeoutException ex) {
        // Close loading window
        return;
    }

    webElement.click();

However, there is a common problem if you are using implicit timeouts in Selenium. This doesn't work too well, particularly if the implicit timeout is longer than the LOADING_TIMEOUT, as this slows down the polling cycle in the wait.until().

In this case, the simplest solution is to temporarily reduce the implicit timeout:

    WebDriverWait wait = new WebDriverWait(driver, LOADING_TIMEOUT);

    WebElement webElement;
    try {
        driver.manage().timeouts().implicitlyWait(1, TimeUnit.SECONDS);
        webElement = wait.until(elementToBeClickable(By.id(id)));
    } catch (TimeoutException ex) {
        // Delay any further interaction until the timeout has been restored
        webElement = null;
    } finally {
        driver.manage().timeouts().implicitlyWait(DEFAULT_TIMEOUT,
                TimeUnit.SECONDS);
    }

    if (webElement != null)
        webElement.click();
    else
        // Close loading window

Check the below links:

• Implicit Wait - It instructs the web driver to wait for some time by poll the DOM. Once you declared implicit wait it will be available for the entire life of web driver instance. By default the value will be 0. If you set a longer default, then the behavior will poll the DOM on a periodic basis depending on the browser/driver implementation.

• Explicit Wait + ExpectedConditions - It is the custom one. It will be used if we want the execution to wait for some time until some condition achieved.

The main issue with the Web Application is that the HTML DOM attains document.readyState equals to complete even before the sub-menu element with text as Selenium WebDriver gets rendered. Hence you see the error as:

Exception in thread "main" org.openqa.selenium.interactions.MoveTargetOutOfBoundsException: (-4899, 91) is out of bounds of viewport width (1366) and height (664)

Solution

So an ideal solution would be:

• Induce WebDriverwait for the titleIs() Execute Automation
• Induce WebDriverwait for the menu element with text as Automation Tools
• Induce WebDriverwait for the sub-menu element with text as Selenium
• Induce WebDriverwait for the sub-menu elementToBeClickable with text as Selenium
• You can use the following solution:

• Code Block:

      import org.openqa.selenium.By;
      import org.openqa.selenium.WebDriver;
      import org.openqa.selenium.firefox.FirefoxDriver;
      import org.openqa.selenium.interactions.Actions;
      import org.openqa.selenium.support.ui.ExpectedConditions;
      import org.openqa.selenium.support.ui.WebDriverWait;
  
      public class MouseHoverFirefox {
  
          public static void main(String[] args) {
  
              System.setProperty("webdriver.gecko.driver", "C:\\Utility\\BrowserDrivers\\geckodriver.exe");
              WebDriver driver=new FirefoxDriver();
              driver.get("http://www.executeautomation.com/demosite/index.html");
              new WebDriverWait(driver, 20).until(ExpectedConditions.titleIs("Execute Automation"));
              new Actions(driver).moveToElement(new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//span[@id='Automation Tools']")))).build().perform();
              new Actions(driver).moveToElement(new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//li[@class='active has-sub']/a/span//following::ul[1]/li[@class='has-sub']/a/span[@id='Selenium']")))).build().perform();
              new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//li[@class='active has-sub']/a/span//following::ul[1]/li/a/span[@id='Selenium']//following::ul[1]/li/a/span[text()='Selenium WebDriver']"))).click();
