how to perform mouse hover in selenium web driver

There will be a situation where you need to hover on a menu item to see the sub items listed under it. Selenium might not recognize the link text to be selected within the short fraction of time the sub menu item visible. In this case we can use Action class to move the focus to the sub menu item to help selenium in recognizing the web element.

Below code snippet can be used to achieve this

WebElement element = driver.findElement(By.linkText("Menu"));

Actions action = new Actions(driver);

action.moveToElement(element).perform();

WebElement subElement = driver.findElement(By.linkText("SubMenu"));

action.moveToElement(subElement).build().perform();

how to verify if WebElement exists in selenium webdriver

You can use any of the below 3 functions to verify if a particular web element exists in your web application using selenium web driver.

Sample code for the same looks like below:

driver.findElement("your locator code here").isDisplayed();

This function returns Boolean value "TRUE" if the web element as per the locator exists and displayed in your application. else it will return False.

In the same way, you can use isSelected(), isEnabled() functions to check if a web element is selected or enabled in your web application.
