Avoiding exception when trying to find a non existing element

[VVP]

Hi All,

 I am excepting an element which sometimes shows up and someother time doesnt and it depends on testcase. But in our code we have something like below.

Element adjustmentDetailsWindow = Manager.ActiveBrowser.Find.ById("viewDetailsContentWindow");

So problem is when window is present, we get correct results, but if window is not present, then we get an exception saying "Object Reference not set to isntance of object"

I put them in try catch block.But is there any better way to avoid exception as well when window is not present.?

Thanks,

VVP

Hi Vishnu,

The try/catch block is probably the best option here.

Another option is to use if/else block to check whether the element is null or not and then take some action against it.

Hope this helps.

How to find out whether element is null?

I couldn't find any options to check for null.

Thanks,

Hi Vishnu,

Just simply write:

if(element==null)
{
}
else
{
}

Let me know if this helps.

Hi Boyan Boev,

Exception will be thrown when we try to find the element. So your code wont work.

Element e1 = Manager.ActiveBrowser.Find.ById("duplicateview");

Will throw exception if element with id "duplicateview" is not present.

 

Thanks,

Hi,

You can try the following:

Element e1 = Manager.ActiveBrowser.Find.ById("duplicateview");
Assert.IsNull(e1);
