How to write Assert condition to check a particular element is not displayed for dummy users?

By.xpath("//button[@id='Edit']")

• This particular Edit button should be displayed for Admin users
• If we login with a different user, we are not showing them the Edit Button
• How to write Assert condition to verify Edit button is not displayed for other users

>Solution :

I will search for all elements with this XPath and put them in List:

List<WebElement> elements = driver.findElements(By.Xpath("//button[@id='Edit']"));

Then I will check if the count (size) of the elements in the list is zero, this will mean that the element was not found.
