How to use CdpInfo class of org.openqa.selenium.devtools package

I find a solution here but if you find better, you can post an other response:

CAUTION: If you use this on unix without GUI, you have this error:

No X11 DISPLAY variable was set, but this program performed an operation which requires it.

I look Xvfb plugin for Jenkins and Travis-ci and I re-edit this post.

EDIT 1:

If you use this on unix without GUI, you can use Jenkins + Xvfb plugin.

You will have to use below hack to access the local storage in RemoteWebDriver . Tested it on chrome browser using RemoteWebdriver selenium-java - 4.0.0-alpha-2 , Chrome Version 76.0.3809.100 and ChromeDriver 76.0.3809.68 . Working fine for me.

Import below classes

 import org.openqa.selenium.remote.RemoteExecuteMethod;
 import org.openqa.selenium.remote.html5.RemoteWebStorage;
 import org.openqa.selenium.html5.LocalStorage;

Use below code to access the local storage

 RemoteExecuteMethod executeMethod = new RemoteExecuteMethod((RemoteWebDriver) driver);
 RemoteWebStorage webStorage = new RemoteWebStorage(executeMethod);
 LocalStorage storage = webStorage.getLocalStorage();
 storage.setItem("test", "test");

Your all xpath are looks OK, Just some syntactically incorrect. you are missing // in your xpath

The correct xpath are as below :-

By by = By.xpath("//span[.='Settings']")

Or

By by = By.xpath("//span[text()='Settings']")

Or

By by = By.xpath("//div[@class='settings-padding']/span"))

Or you can use cssSelector as :-

By by = By.cssSelector("div.settings-padding > span"))

Using anyone of the above By locator you can locate element as below :-

WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement el = wait.until(presenceOfElementLocated(by));

Hope it helps...:)

selenium doesn't support it, only web page shots. However you can use Robot to do it

try {
    String format = "jpg";
    String fileName = printScreen." + format;

    Rectangle screenRect = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
    Robot robot = new Robot();
    BufferedImage screenFullImage = robot.createScreenCapture(screenRect);
    ImageIO.write(screenFullImage, format, new File(fileName));

} catch (AWTException | IOException ex) {
    System.err.println(ex);
}

And in C#

using System.Drawing;
using System.Drawing.Imaging;
using System.Windows.Forms;

Bitmap bitmap = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);
Graphics graphics = Graphics.FromImage(bitmap);
graphics.CopyFromScreen(0, 0, 0, 0, bitmap.Size);
bitmap.Save(@"C:\ScreenShots\printScreen.jpg", ImageFormat.Jpeg);

In my experience the Selenium API has many flaws in that way. They can mostly only be overcome by reformulating your selectors. For example you could try using a XPath selector to get your element:

driver.findElement(By.xpath("//a[contains(.,'About')]")).click();

Also, if you are trying to use the Internet Explorer it might help not to click the element, but instead to simulate pushing the Enter button. So assumung the Element is found, you could try this:

driver.findElement(By.linkText("About")).sendKeys(Keys.ENTER);

You can control how the Firefox driver chooses the profile. Set the webdriver.firefox.profile property to the name of the profile you want to use. Most folks think this is a bad idea, because you'll inherit all the cookies, cache contents, etc. of the previous uses of the profile, but it's allowed if you really want to do it.

For example:

System.setProperty("webdriver.firefox.profile", "MySeleniumProfile");
WebDriver driver = new FirefoxDriver(...);

UPDATE - From Ranhiru

How I handled it for Java

FirefoxProfile profile = new FirefoxProfile(new File("D:\\Selenium Profile"));                  
WebDriver driver = new FirefoxDriver(profile);

Then I changed settings in Firefox to clear all cookies and cache when exiting. Look here on how to do it.

I've run into the same issue.

Apparently Chrome automatically updates itself. Yesterday (Oct 29 '19) My ChromeDriver started complaining that it was not compatible with Chrome 78. I updated the driver to the 78 version. I started to get random org.openqa.selenium.NoSuchElementException exceptions when trying to find elements that I confirmed were there. The findElement[s] also work when I used breakpoints. I also tried implicit waits, with only limited success.

I tried zsbappa's ChromeOption solution but no joy.

Google makes it hard to get old versions of Chrome, but I found version 76 at https://www.neowin.net/news/google-chrome-76-offline-installer/. Beware, the online installer installs the latest version. I reverted to the driver for 76 and all is good. All my Selenium tests are working again.

My conclusion is that the Chrome 78 and it's associated driver has a race condition where Selenium attempts to interrogate the web page before it's complete.

You can also check pageloaded using following code

IWait<IWebDriver> wait = new OpenQA.Selenium.Support.UI.WebDriverWait(driver, TimeSpan.FromSeconds(30.00));

 wait.Until(driver1 => ((IJavaScriptExecutor)driver).ExecuteScript("return document.readyState").Equals("complete"));

This is just a version mismatch. You have compiled your code using java version 9 and your current JRE is version 8. Try upgrading your JRE to 9.

49 = Java 5
50 = Java 6
51 = Java 7
