How to get an item count from a drop-down box

[Jeff]

How do I get the total count of items listed in a drop-down box.  For example, I have a smoke test that needs to verify that a drop-down box contains at least one item.  How can I use the built-in verification functionality to accomplish this?  Assistance appreciated in advance.

Hi Jeff,
   the term drop-down encompasses a multitude of controls. What kind of a drop-down control is it? For a completely generic drop-down (i.e. an HTML Select) like this one:
http://www.w3schools.com/html/tryit.asp?filename=tryhtml_select2
you will need a coded step. I've attached a test that uses code to get the number of items for this drop-down and write them to the log. Depending on the particular dropdown used in your app the coded solution will look differently. Also, Test Studio might be able to build non-coded Verifications for some type of drop-down controls.

Hope to hear from you soon!

Kind regards,

This is a jquery drop down

$(

 

'#CustomerId').size();

 

should get me the item count, no?  But how would I write a verification to ensure that there is at least one value?  I am not familiar with C#.

Hello Jeff,
   you'll need to go into the DOM structure of the application and examine how the items in the drop down are defined. Let's take the following application:
http://www.queness.com/resources/html/dropdownmenu/index.html#
We have 4 jquery drop-downs. When we bring up the DOM Explorer and we examine them we see that the items for each drop-down are defined in a UL (HTML Unordered List) (see screenshot 1). Now you can add the Unorder List item to the Elements Repository (screenshot 2).

Now you can access this element from a coded step:

Pages.SimpleDropDownMenu.UnorderedList

You're looking for the number of items in the menu. This corresponds to the number of LI elements inside of the UL. Since the LI elements are children of the UL you can use the following code to get their count:

Pages.SimpleDropDownMenu.UnorderedList.ChildNodes.Count

And you can write this value to the Log like this:

Log.WriteLine("Number of items in drop-down:"+Pages.SimpleDropDownMenu.UnorderedList.ChildNodes.Count.ToString());

I've attached the Test Project with the test demonstrating this example. I hope this helps.

Best wishes,
