Siva,
So, this is the part about asynchronous code that takes a moment to get
your head around. findElement is returning a Promise, not the Element
object as you would expect in Java. To get the result of the findElement
function you need to wait until it's complete evaluating the function. You
can do this in two ways:
// assuming e.isEmpty() is a method of the returned element...
findElement(By.xpath("//xxx")).then( (e) => {
e.isEmpty();
});
Or using async/await :
let e = await findElement(By.xpath("//xxx"));
e.isEmpty();
HTH,
Mikkel
