Suppose you want to test that when you hover over an element, a drop list is displayed. You may want to check the contents of this list, or perhaps select an option from the list.
First create an Action, to hover over the element (e.g. my element has link text "Admin"):
Actions mouseHover = new Actions(driver);
mouseHover.MoveToElement(driver.FindElement(By.LinkText("Admin"))).Perform();
In the example above:
mouseHoverdriver to move to a specific elementActions with the mouseHover object or continue testing with your driver objectThis approach is of particular use when clicking on an element performs a different function than hovering over it.
A full example:
Actions mouseHover = new Actions(driver);
mouseHover.MoveToElement(driver.FindElement(By.LinkText("Admin"))).Perform();
Assert.IsTrue(driver.FindElement(By.LinkText("Edit Record")).Displayed);
Assert.IsTrue(driver.FindElement(By.LinkText("Delete Record")).Displayed);
