How to use SingleTapAction class of org.openqa.selenium.interactions.touch package

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();
        }
    }
}

It's the number of tests that are run at the same time. It takes up more slots in the grid because is uses one grid slot per test run. It's like saying how many cars in a fleet that you want on the highway at the same time. If you say you want them to take up three lanes, then they will take up no more than three lanes, but it will take longer to get all cars through. If you say five lanes, then they will take up no more than five lanes, but it will take less time to get all cars through.

This error message...

java.lang.NoSuchMethodError: 'java.util.stream.Collector com.google.common.collect.ImmutableList.toImmutableList()'

...implies that there is some incompatibility between the version of the binaries you are using.

The Selenium project with Junit in which you see this error have mismatched versions of guava installed.

Solution

You need to configure compatible version of guava as per the list below:

• Selenium v2.49.0 : Bump guava to version 19
• Selenium v3.1.0 : Requires an update to the latest guava version 21.0
• Selenium v3.5.0 : Bump guava to version 22.
• Selenium v3.5.1 : Bump guava to version 23.
• Selenium v3.12.0 : guava-23.6-jre
• Selenium v3.13.0 : guava-25.0-jre
• Selenium v3.14.0 : guava-25.0-jre
• Selenium v3.141.0 : guava-25.0-jre
• Selenium v3.141.5 : guava-25.0-jre
• Selenium v3.141.59 : guava-25.0-jre

This error message...

org.openqa.selenium.ElementClickInterceptedException: element click intercepted: Element <label _ngcontent-yrc-c26="" formcontrolname="reportingDealPermission" nz-checkbox="" class="ant-checkbox-wrapper ng-untouched ng-pristine ng-valid" ng-reflect-name="reportingDealPermission">...</label> is not clickable at point (161, 562). Other element would receive the click: <div _ngcontent-yrc-c26="" class="footer">...</div>

...implies that the click on the desired element was intercepted by some other element.

Clicking an element

Ideally, while invoking click() on any element you need to induce WebDriverWait for the elementToBeClickable() and you can use either of the following Locator Strategies:

• cssSelector:

  new WebDriverWait(getWebDriver(), 10).until(ExpectedConditions.elementToBeClickable(By.cssSelector("label[formcontrolname=reportingDealPermission][ng-reflect-name=reportingDealPermission]"))).click();
  

• xpath:

  new WebDriverWait(getWebDriver(), 10).until(ExpectedConditions.elementToBeClickable(By.xpath("//label[@formcontrolname='reportingDealPermission' and @ng-reflect-name='reportingDealPermission']"))).click();
  

Update

After changing to headless if it still doesn't works and still get exception there still a couple of other measures to consider as follows:

• Chrome browser in Headless mode doesn't opens in maximized mode. So you have to use either of the following commands/arguments to maximize the headless browser Viewport:

  • Adding the argument start-maximized

    ChromeOptions options = new ChromeOptions();
    options.addArguments("--headless");
    options.addArguments("start-maximized");
    WebDriver driver = new ChromeDriver(options);
    

  • Adding the argument --window-size

    ChromeOptions options = new ChromeOptions();
    options.addArguments("--headless");
    options.addArguments("--window-size=1400,600");
    WebDriver driver = new ChromeDriver(options);
    

  • Using setSize()

    ChromeOptions options = new ChromeOptions();
    options.addArguments("--headless");
    WebDriver driver = new ChromeDriver(options);
    driver.manage().window().setSize(new Dimension(1440, 900));
    

You can find a detailed discussion in Not able to maximize Chrome Window in headless mode

• Additionally, you can also wait for the intercept element to be invisible using the ExpectedConditions invisibilityOfElementLocated before attempting the click() as follows:

  • cssSelector:

    new WebDriverWait(getWebDriver(), 10).until(ExpectedConditions.invisibilityOfElementLocated(By.cssSelector("div.footer")));
    new WebDriverWait(getWebDriver(), 10).until(ExpectedConditions.elementToBeClickable(By.cssSelector("label[formcontrolname=reportingDealPermission][ng-reflect-name=reportingDealPermission]"))).click();
    

  • xpath:

    new WebDriverWait(getWebDriver(), 10).until(ExpectedConditions.invisibilityOfElementLocated(By.xpath("//div[@class='footer']")));
    new WebDriverWait(getWebDriver(), 10).until(ExpectedConditions.elementToBeClickable(By.xpath("//label[@formcontrolname='reportingDealPermission' and @ng-reflect-name='reportingDealPermission']"))).click();

You don't need to convert the whole array. Just call File's getAbsolutePath() method:

driver.findElement(By.id(id1)).sendKeys(listOfFiles[1].getAbsolutePath());

But if you do want to convert the whole array, here is the Java 8 way to do this (simplified by @RemigiusStalder):

String listOfPaths[] = Arrays.stream(listOfFiles).map(File::getAbsolutePath)
        .toArray(String[]::new);

You are using latest version of Selenium WebDriver i.e. Selenium 3.x, this version of webdriver doesn't support direct firefox launch. You have to set the SystemProperty for webdriver.gecko.driver.

Replace the Code:-

WebDriver driver;
driver =new FirefoxDriver();

With This code:-

WebDriver driver;
System.setProperty("webdriver.gecko.driver", "<Path to your WebDriver>");
driver =new FirefoxDriver();

You can get the information about latest changes here

You can download the latest Gecko driver from here

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"));

I believe you have several options:

Either specify the folder (in which your Firefox binary is) in your PATH system variable - here's how.

Or call

WebDriver driver = new FirefoxDriver(new FirefoxBinary(new File("path/to/your/firefox.exe")), profile);

I would simply disable the print dialog by overriding the print method :

((JavascriptExecutor)driver).executeScript("window.print=function(){};");

But if you goal is to test that the printing is called then :

// get the print button
WebElement print_button = driver.findElement(By.cssSelector("..."));

// click on the print button and wait for print to be called
driver.manage().timeouts().setScriptTimeout(20, TimeUnit.SECONDS);
((JavascriptExecutor)driver).executeAsyncScript(
    "var callback = arguments[1];" +
    "window.print = function(){callback();};" +
    "arguments[0].click();"
    , print_button);
