How to check if an element is visible with WebDriver

Question

With WebDriver from Selenium 2.0a2 I am having trouble checking if an element is visible.

WebDriver.findElement returns a WebElement<

Answer 1

It is important to see if the element is visible or not as the Driver.FindElement will only check the HTML source. But popup code could be in the page html, and not be visible. Therefore, Driver.FindElement function returns a false positive (and your test will fail)
