How to check if dom has a class using WebDriver (Selenium 2)?

Question

I am very new to Selenium, so my apologies if it's a silly question. I have successfully wired up IntelliJ (Play! framework) with Selenium, and created some tests using firefoxDrivers.

I'm trying to check if the page had been validated properly.

long story short, I'm selecting an element like this:

WebElement smallDecel = firefoxDriver.findElement(By.cssSelector("#configTable tr:nth-child(2) td .playerDecelInput")); 

I do some further operations (clear and change the value, submit the 'form'), and then I want to check if the TD the input sits in was given another class.

So, the question is - is there a simple technique I can use to find out if a WebElement / DOM has a class specified?

Answer 1

To expand on Sam Woods' answer, I use a simple extension method (this is for C#) to test whether or not an element has a specified class:

public static bool HasClass( this IWebElement el, string className ) {     return el.GetAttribute( "class" ).Split( ' ' ).Contains( className ); } 

Answer 2

Once you find the element, you can just call myElement.GetAttribute("class"). Then you can parse the string that is returned and see if it contains or does not contain the class name you care about.
