Wait for element in webdriver

selenium-webdriverwebdriver

I followed what was written here:
WebDriver Selenium API: ElementNotFoundErrorException when Element is clearly there !

My code looks like:

    Function<WebDriver, WebElement> presenceOfElementLocated(final By locator) {
    return new Function<WebDriver, WebElement>() {
        public WebElement apply(WebDriver driver) {
            return driver.findElement(locator);
          }
       };
    }

   ....... 

   driver.get(baseUrl);

   WebDriverWait wait = new WebDriverWait(driver, 10);
   wait.until(presenceOfElementLocated(By.className("classname")));
   findByClassAndName(driver, "x-tree3-node-text", "Name1").click();

Problem is, that is does not seem to do anything. It doesn't work and i can't even see slightest trace of waiting for webpage gui. i got the same with implicit wait through timeouts… Anyone could help?

You have to catch Throwables throwed from ExpectedCondition or your Function (the apply() methods is good place for that) and return null so Wait.until() continues to run - see http://rostislav-matl.blogspot.com/2011/05/moving-to-selenium-2-on-webdriver-part.html for detailed example.

Python – Get HTML source of WebElement in Selenium WebDriver using Python

You can read the innerHTML attribute to get the source of the content of the element or outerHTML for the source with the current element.

Python:

element.get_attribute('innerHTML')

Java:

elem.getAttribute("innerHTML");

C#:

element.GetAttribute("innerHTML");

Ruby:

element.attribute("innerHTML")

JavaScript:

element.getAttribute('innerHTML');

PHP:

$element->getAttribute('innerHTML');

It was tested and worked with the ChromeDriver.

Selenium WebDriver: Fluent wait works as expected, but implicit wait does not

Remember that there is a difference between several scenarios:

An element not being present at all in the DOM.
An element being present in the DOM but not visible.
An element being present in the DOM but not enabled. (i.e. clickable)

My guess is that if some of the page is being displayed with javascript, the elements are already present in the browser DOM, but are not visible. The implicit wait only waits for an element to appear in the DOM, so it returns immediately, but when you try to interact with the element you get a NoSuchElementException. You could test this hypothesis by writing a helper method that explicits waits for an element to be be visible or clickable.

Some examples (in Java):

public WebElement getWhenVisible(By locator, int timeout) {
    WebElement element = null;
    WebDriverWait wait = new WebDriverWait(driver, timeout);
    element = wait.until(ExpectedConditions.visibilityOfElementLocated(locator));
    return element;
}

public void clickWhenReady(By locator, int timeout) {
    WebDriverWait wait = new WebDriverWait(driver, timeout);
    WebElement element = wait.until(ExpectedConditions.elementToBeClickable(locator));
    element.click();
}
