How to use getEncodedElementKey method of org.openqa.selenium.remote.Enum Dialect class

I also faced the same issue in IntelliJ idea, When I check in the imported libraries it was like below screenshot.

So I remove scope tag from my import in pom file.Then it worked.

Earlier

<dependency>
    <groupId>info.cukes</groupId>
    <artifactId>cucumber-junit</artifactId>
    <version>1.2.5</version>
    <scope>test</scope>
</dependency>

Fix

<dependency>
    <groupId>info.cukes</groupId>
    <artifactId>cucumber-junit</artifactId>
    <version>1.2.5</version>
</dependency>

Now it is working fine

Just for anyone else who's looking for an answer in Ruby, Python, and C# bindings (Selenium 2.33.0).

Note that the actual keys to send depend on your OS. For example, Mac uses CMD + T, instead of Ctrl + T.

Ruby

require 'selenium-webdriver'

driver = Selenium::WebDriver.for :firefox
driver.get('http://stackoverflow.com/')

body = driver.find_element(:tag_name => 'body')
body.send_keys(:control, 't')

driver.quit

Python

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://stackoverflow.com/")

body = driver.find_element_by_tag_name("body")
body.send_keys(Keys.CONTROL + 't')

driver.close()

C#

using OpenQA.Selenium;
using OpenQA.Selenium.Firefox;

namespace StackOverflowTests {

    class OpenNewTab {

        static void Main(string[] args) {

            IWebDriver driver = new FirefoxDriver();
            driver.Navigate().GoToUrl("http://stackoverflow.com/");

            IWebElement body = driver.FindElement(By.TagName("body"));
            body.SendKeys(Keys.Control + 't');

            driver.Quit();
        }
    }
}

Am using bellow code to get link location (With Selenium-WebDriver and java binding) :

WebElement link = driver.findElement(By.linkText("add book"));
String linkLocatin = link.getAttribute("href");
System.out.println("Link Location "+linkLocatin);

After inspecting the selenium Python API docs and the source code, I can conclude - there is no such a method. And, there is nothing about it inside the WebDriver specification itself.

To set an attribute, usually a script is executed:

elm = driver.find_element_by_id("myid")
driver.execute_script("arguments[0].setAttribute(arguments[1], arguments[2]);", 
                      elm,  
                      "attr_name",
                      "attr_value")

The value attribute stores the content of a tag, does not matter whether it is disabled or not. So, you can do it like this:

driver.findElement(By.id("write_element_id_here")).getAttribute("value");

this will return you the value of the element and then you can proceed with the rest. Hope it helps..

You will have to download the "Selenium Client & WebDriver Language Bindings" for Java from Selenium Downloads. You can download directly by clicking the link here.

Include all the JAR files that are present in the downloaded ZIP file. To include multiple JARs in Java classpath, you can check the link here.

The selenium-server-standalone JAR is required if you are running your tests locally. Executing the command java -jar selenium-server-standalone-2.48.2.jar will start a Selenium server, which required to launch Selenium tests locally. You need not use it, if you are running tests on BrowserStack.

Would also recommend using an IDE for Java. The most commonly recommended ones are IntelliJ Idea, Eclipse, and Netbeans.

The Selenium client bindings will try to locate the geckodriver executable from the system PATH. You will need to add the directory containing the executable to the system path.

• On Unix systems you can do the following to append it to your system’s search path, if you’re using a bash-compatible shell:

  export PATH=$PATH:/path/to/geckodriver
  

• On Windows you need to update the Path system variable to add the full directory path to the executable. The principle is the same as on Unix.

All below configuration for launching latest firefox using any programming language binding is applicable for Selenium2 to enable Marionette explicitly. With Selenium 3.0 and later, you shouldn't need to do anything to use Marionette, as it's enabled by default.

To use Marionette in your tests you will need to update your desired capabilities to use it.

Java :

As exception is clearly saying you need to download latest geckodriver.exe from here and set downloaded geckodriver.exe path where it's exists in your computer as system property with with variable webdriver.gecko.driver before initiating marionette driver and launching firefox as below :-

//if you didn't update the Path system variable to add the full directory path to the executable as above mentioned then doing this directly through code
System.setProperty("webdriver.gecko.driver", "path/to/geckodriver.exe");

//Now you can Initialize marionette driver to launch firefox
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
WebDriver driver = new MarionetteDriver(capabilities); 

And for Selenium3 use as :-

WebDriver driver = new FirefoxDriver();

If you're still in trouble follow this link as well which would help you to solving your problem

.NET :

var driver = new FirefoxDriver(new FirefoxOptions());

Python :

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

caps = DesiredCapabilities.FIREFOX

# Tell the Python bindings to use Marionette.
# This will not be necessary in the future,
# when Selenium will auto-detect what remote end
# it is talking to.
caps["marionette"] = True

# Path to Firefox DevEdition or Nightly.
# Firefox 47 (stable) is currently not supported,
# and may give you a suboptimal experience.
#
# On Mac OS you must point to the binary executable
# inside the application package, such as
# /Applications/FirefoxNightly.app/Contents/MacOS/firefox-bin
caps["binary"] = "/usr/bin/firefox"

driver = webdriver.Firefox(capabilities=caps)

Ruby :

# Selenium 3 uses Marionette by default when firefox is specified
# Set Marionette in Selenium 2 by directly passing marionette: true
# You might need to specify an alternate path for the desired version of Firefox

Selenium::WebDriver::Firefox::Binary.path = "/path/to/firefox"
driver = Selenium::WebDriver.for :firefox, marionette: true

JavaScript (Node.js) :

const webdriver = require('selenium-webdriver');
const Capabilities = require('selenium-webdriver/lib/capabilities').Capabilities;

var capabilities = Capabilities.firefox();

// Tell the Node.js bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.set('marionette', true);

var driver = new webdriver.Builder().withCapabilities(capabilities).build();

Using RemoteWebDriver

If you want to use RemoteWebDriver in any language, this will allow you to use Marionette in Selenium Grid.

Python:

caps = DesiredCapabilities.FIREFOX

# Tell the Python bindings to use Marionette.
# This will not be necessary in the future,
# when Selenium will auto-detect what remote end
# it is talking to.
caps["marionette"] = True

driver = webdriver.Firefox(capabilities=caps)

Ruby :

# Selenium 3 uses Marionette by default when firefox is specified
# Set Marionette in Selenium 2 by using the Capabilities class
# You might need to specify an alternate path for the desired version of Firefox

caps = Selenium::WebDriver::Remote::Capabilities.firefox marionette: true, firefox_binary: "/path/to/firefox"
driver = Selenium::WebDriver.for :remote, desired_capabilities: caps

Java :

DesiredCapabilities capabilities = DesiredCapabilities.firefox();

// Tell the Java bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.setCapability("marionette", true);

WebDriver driver = new RemoteWebDriver(capabilities); 

.NET

DesiredCapabilities capabilities = DesiredCapabilities.Firefox();

// Tell the .NET bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.SetCapability("marionette", true);

var driver = new RemoteWebDriver(capabilities); 

Note : Just like the other drivers available to Selenium from other browser vendors, Mozilla has released now an executable that will run alongside the browser. Follow this for more details.

You can download latest geckodriver executable to support latest firefox from here

Here is the Answer to your Question:

The error says it all The type List is not generic; it cannot be parameterized with arguments <WebElement> type. It means when you configured the List as in List<WebElement> linkElements, accidentally you have imported it from java.awt.List where it is not defined. Hence the error.

The following screenshot shows it all:

Solution:

As a solution, I have used your own code importing java.util.List instead of java.awt.List and your code block works just fine:

package demo;

import java.util.List;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;

public class Q45402867_tagname_a {

    public static void main(String[] args) {
        System.setProperty("webdriver.gecko.driver","C:\\Utility\\BrowserDrivers\\geckodriver.exe");  
        WebDriver driver=new FirefoxDriver();
        String baseUrl="https://www.udacity.com/";
        driver.get(baseUrl);
        String Title="Udacity - Free Online Courses and Nanodegree Programs";
        List<WebElement> linkElements = driver.findElements(By.tagName("a"));
        System.out.println(linkElements.size());
        for (WebElement ele:linkElements)
        System.out.println(ele);
    }

}

The output on the console is:

86
[[FirefoxDriver: firefox on ANY (ef81931f-9530-4998-8405-6581ab51c86e)] -> tag name: a]
...  84 more ...
[[FirefoxDriver: firefox on ANY (ef81931f-9530-4998-8405-6581ab51c86e)] -> tag name: a]

Let me know if this Answers your Question.

Given you already found your element and you want to check for a certain class inside the class-attribute:

public boolean hasClass(WebElement element) {
    String classes = element.getAttribute("class");
    for (String c : classes.split(" ")) {
        if (c.equals(theClassYouAreSearching)) {
            return true;
        }
    }
    
    return false;
}

#EDIT As @aurelius rightly pointed out, there is an even simpler way (that doesn't work very well):

public boolean elementHasClass(WebElement element, String active) {
    return element.getAttribute("class").contains(active);
}

This approach looks simpler but has one big caveat:

As pointed out by @JuanMendes you will run into problems if the class-name you're searching for is a substring of other class-names:

for example class="test-a test-b", searching for class.contains("test") will return true but it should be false

#EDIT 2 Try combining the two code snippets:

public boolean elementHasClass(WebElement element, String active) {
    return Arrays.asList(element.getAttribute("class").split(" ")).contains(active);
}

That should fix your caveat.
