How to use sendAndWait method of org.openqa.selenium.devtools.Connection class

Given that Selenium doesn't seem to offer what I want directly (based on what Mike Kwan and Slanec said), this simple helper method is what I went with for now:

protected boolean isElementHiddenNow(String id) {
    turnOffImplicitWaits();
    boolean result = ExpectedConditions.invisibilityOfElementLocated(By.id(id)).apply(driver);
    turnOnImplicitWaits();
    return result;
}

private void turnOffImplicitWaits() {
    driver.manage().timeouts().implicitlyWait(0, TimeUnit.SECONDS);
}

private void turnOnImplicitWaits() {
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
}

If the element is hidden or not present at all, the method returns true; if it is visible, returns false. Either way, the check is done instantly.

Using the above is at least much cleaner than littering the test cases themselves with calls to turnOffImplicitWaits() and turnOnImplicitWaits().

See also these answers for fined-tuned versions of the same approach:

• Using try-finally to turn implicit waits back on
• Using By locator as the parameter

Try combining all the action into one action as shown below and try again.

public class Helper {

public static void scrollToElementAndClick(WebDriver driver, WebElement webelement){
Actions actions = new Actions(driver);
actions.moveToElement(webelement).click();

action = action.build;
action.perform();

}

Also you can try JavascriptExecuter as shown below:

((JavascriptExecutor)driver).executeScript("arguments[0].click();", selectAddress); 

Also consider the possibility of the td containing some other element (input, link) which can be clicked(I dont know your html code).

Hope this helps you.

You are using drive.quit() instead of driver.close(). quit closes the driver and window. This is why you get the child error because the driver is no longer available. close(), will close the window but keep the driver alive. I would only use quit at the very end of your program (like a cleanup routine). I ran your code (modified below) on my machine and did not have any errors. Also, you should put this around a try/catch so that you can see what is going on. I found with selenium that the try/catch sometimes shows errors that your console does not show. I had something similar with an earlier project and the try catch assisted with debugging.

package com.kurt.stackoverflow.selenium;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class Gecko_Driver
{
    public static void main(String[] args) throws InterruptedException{

    try
    {
       System.setProperty("webdriver.gecko.driver","C:\\tmp\\geckodriver-v0.11.1-win64\\geckodriver.exe");
       WebDriver driver = new FirefoxDriver();
       driver.get("http://www.toolsqa.com");
       Thread.sleep(5000);
       driver.close();
    }
    catch (Exception e)
    {
       System.out.println("Caught message " + e.getMessage());
       driver.close();
    }
}

}

Use -

new Select(driver.findElement(By.id("gender"))).selectByVisibleText("Germany");

Of course, you need to import org.openqa.selenium.support.ui.Select;

driver.submit()

should work. If the order of the buttons in your DOM is always the same, this should work too:

driver.findElements(By.className("buttonLargeAlt")).get(0).click();

if it is the first buttonLargeAlt button on your page.

The details aren't clear but it looks like you are trying to print the links in the INDUSTRIES section of the footer. If that's true, this should work.

driver.get("https://dev.www.tycois.com/");
WebElement industries = driver.findElement(By.cssSelector("div.columns.three.alpha > ul"));
List<WebElement> links = industries.findElements(By.tagName("li"));
for (int i = 1; i < links.size(); i++)
{
    System.out.println(links.get(i).getText());
}

You can't click the links in this loop because once you click the first one, you will no longer be on the page. I would suggest that you store the URLs from each link in an array and then driver.get(url) for each one. Or you could store the expected URLs in an array and compare the URLs from the links to the expected URLs and not have to navigate at all. The choice is up to you...

On Linux, you can start up a vncserver on a different display (say, :8 or something) and then have Selenium and your Firefox instances use that display. Works well for us where I work.

java.lang.UnsupportedClassVersionError happens because the code was compiled with a higher version of Java than the one you're running it.

Version 51.0 of a class file corresponds to java 7

J2SE 8 = 52,
J2SE 7 = 51,
J2SE 6.0 = 50,
J2SE 5.0 = 49,
JDK 1.4 = 48,
JDK 1.3 = 47,
JDK 1.2 = 46,
JDK 1.1 = 45

You need to upgrade your JDK from Java 6 to Java 7 or higher.

You could execute some javascript to interrogate the DOM. Specifically, the complete property of an HTMLImageElement.

public static void waitUntilVisible(WebDriver webDriver, By locator) {
    WebDriverWait driverWait = new WebDriverWait(webDriver, TIMEOUT);
    WebElement el = webDriver.findElement(locator);
    driverWait.until(
        new Predicate<WebDriver>() {
            public boolean apply(WebDriver driver) {
                return ((JavascriptExecutor)driver).executeScript("return arguments[0].complete", el);
            }
        }
    );
}

But note that complete:

Returns a Boolean that is true if the browser has finished fetching the image, whether successful or not. It also shows true, if the image has no src value.
