Create cookies using the Java API as follows:

Cookie ck = new Cookie("name", "value");
driver.manage().addCookie(ck);

Create cookies using the Python API as follows:

driver.add_cookie({'name': 'foo', 'value': 'bar'})

Try something this, Change the path and slashing accoding to your specifications :-

            WebDriver driver=null;
            System.setProperty("webdriver.chrome.driver","./src//lib//chromedriver");
            DesiredCapabilities capabilities = DesiredCapabilities.chrome();
            ChromeOptions options = new ChromeOptions();
            options.addArguments("test-type");
            options.addArgument("--start-maximized");
            options.addArguments("--disable-web-security");
            options.addArguments("--allow-running-insecure-content");
            capabilities.setCapability("chrome.binary","./src//lib//chromedriver");
            capabilities.setCapability(ChromeOptions.CAPABILITY, options);
            driver = new ChromeDriver(capabilities);
            driver.get("https://www.google.com/");

Hope it will help you :)

Here is how I am sending character by character using Selenium Webdriver (in Java). This way in the back-end, I verify at each letter press if the character exists in the input. Normal element.sendKeys() is not working well for me 2 out of 5 times - the last letter is missing, I guess something is buggy with Selenium Webdriver, I don't know. Try the code below, it works 100% of the time for me.

public void TypeInField(String xpath, String value){
    String val = value; 
    WebElement element = driver.findElement(By.xpath(xpath));
    element.clear();

    for (int i = 0; i < val.length(); i++){
        char c = val.charAt(i);
        String s = new StringBuilder().append(c).toString();
        element.sendKeys(s);
    }       
}

As you see, I get the value needed to be typed and in the for loop, I take each character, convert it to string and send it to textbox. Also, I have a search for xpath, you can change that to id, or classname, or whatever you want.

I found a google groups discussion on the topic. These links look like promising alternative to Browsermob:

• A Selenium CaptureNetworkTraffic Example in Java
• HOWTO: Collect WebDriver HTTP Request and Response Headers
• Automating the Capture of Web Timings with Selenium 2

First of all lets be clear about what a WebElement is.

A WebElement is a reference to an element in the DOM.

A StaleElementException is thrown when the element you were interacting is destroyed and then recreated. Most complex web pages these days will move things about on the fly as the user interacts with it and this requires elements in the DOM to be destroyed and recreated.

When this happens the reference to the element in the DOM that you previously had becomes stale and you are no longer able to use this reference to interact with the element in the DOM. When this happens you will need to refresh your reference, or in real world terms find the element again.

While working with Selenium v3.11.x, GeckoDriver v0.20.0 and Firefox Quantum v59.0.2 there are different option to invoke a new/existing Firefox Profile

If you are looking to use a new Firefox Profile on every run of your Test Execution you can use the following code block :

System.setProperty("webdriver.gecko.driver", "C:\\path\\to\\geckodriver.exe");
FirefoxOptions options = new FirefoxOptions();
options.setProfile(new FirefoxProfile());
WebDriver driver = new FirefoxDriver(options);
driver.get("https://www.google.com");

If you are looking to use an existing Firefox Profile on every run of your Test Execution first you have to create a Firefox Profile manually following the instructions at Creating a new Firefox profile on Windows.

Now you have 2 ways to invoke the Firefox Profile you have created as follows :

• You can use the FirefoxOptions class to invoke the existing Firefox Profile and you can use the following code block :

  System.setProperty("webdriver.gecko.driver", "C:\\path\\to\\geckodriver.exe");
  ProfilesIni profile = new ProfilesIni();
  FirefoxProfile testprofile = profile.getProfile("debanjan");
  FirefoxOptions opt = new FirefoxOptions();
  opt.setProfile(testprofile);
  WebDriver driver =  new FirefoxDriver(opt);
  driver.get("https://www.google.com");
  

• You can also use the DesiredCapabilities class to set the existing Firefox Profile and later merge within an instance of FirefoxOptions and you can use the following code block :

  System.setProperty("webdriver.gecko.driver", "C:\\path\\to\\geckodriver.exe");
  ProfilesIni profile = new ProfilesIni();
  FirefoxProfile testprofile = profile.getProfile("debanjan");
  DesiredCapabilities dc = DesiredCapabilities.firefox();
  dc.setCapability(FirefoxDriver.PROFILE, testprofile);
  FirefoxOptions opt = new FirefoxOptions();
  opt.merge(dc);
  WebDriver driver =  new FirefoxDriver(opt);
  driver.get("https://www.google.com");
  

  <input attr1='a' attr2='b' attr3='c'>foo</input>

getAttribute(attr1) you get 'a'

getAttribute(attr2) you get 'b'

getAttribute(attr3) you get 'c'

getText() with no parameter you can only get 'foo'

I had the same question and here is what I found somewhere on the Internet (maybe on stackoverflow, I cannot remember). I just added a line to delete the file so that by calling this method at the beginning of my test, I'm making sure the file does not exist anymore when trying to download it again.

  public boolean isFileDownloaded(String downloadPath, String fileName) {
  File dir = new File(downloadPath);
  File[] dirContents = dir.listFiles();

  for (int i = 0; i < dirContents.length; i++) {
      if (dirContents[i].getName().equals(fileName)) {
          // File has been found, it can now be deleted:
          dirContents[i].delete();
          return true;
      }
          }
      return false;
  }

You just have to call with this single line: isFileDownloaded("C:\Path\To\Your\Folder", "yourPdfFile.abc");

Hope this helps!

Unfortunately

this is not possible with native Selenium API.

But using Javascript you can:

You can use some javascript support, using Seleniums' JavascriptExecutor.executeScript functionality.

The necessary js code can be found here and here(as proposed by @Mahsum Akbas)

Now here is the Java/Selenium Code that will return you a string in the form of "css-attribute01:value01; css-attribute02:value02;".

Be aware that this will return ALL css-attributes on the element.

WebElement we = driver.findElement(By.tagName("div"));
JavascriptExecutor executor = (JavascriptExecutor)driver;
String script = "var s = '';" +
                "var o = getComputedStyle(arguments[0]);" +
                "for(var i = 0; i < o.length; i++){" +
                "s+=o[i] + ':' + o.getPropertyValue(o[i])+';';}" + 
                "return s;";

System.out.println(executor.executeScript(script, we));

You can change the script according to your needs. For example you could return a string that ONLY has all the values without the attributes. Feel free to change and experiment.

Update

If you would be interested in only the inline-styles of the element, then you can use "native" Selenium as pointed out by @JeffC in the comments:

driver.findElement(By.tagName("div")).getAttribute("style")

BUT!:

This will give you only the "inline styles" and NOT all the css-styles that are applied to an element. If you run both versions after one another and print the results you will see the immense difference.
