How to fetch all links and click those links one by one using Selenium WebDriver

Question

I am using Selenium WebDriver with java.

I am fetching all links from webpage and trying to click each link one by one. I am getting below error:

Answer 1

There is no such a good idea to have following scenario :

for (WebElement element : webDriver.findElements(locator.getBy())){
  element.click();
}

Why? Because there is no guarantee that the element.click(); will have no effect on other found elements, so the DOM may be changed, so hence the StaleElementReferenceException.

It is better to use the following scenario :

int numberOfElementsFound = getNumberOfElementsFound(locator);
for (int pos = 0; pos < numberOfElementsFound; pos++) {
  getElementWithIndex(locator, pos).click();
}

This is better because you will always take the WebElement refreshed, even the previous click had some effects on it.

EDIT : Example added

  public int getNumberOfElementsFound(By by) {
    return webDriver.findElements(by).size();
  }

  public WebElement getElementWithIndex(By by, int pos) {
    return webDriver.findElements(by).get(pos);
  }

Hope to be enough.
