Question

How can I check whether a <select> box has more than 1 <option>?
The <option>s are loaded using ajax and are placed into two <optgroup>s.
<option value="">default</option>
<optgroup ...>
<option value=..>...
<option ..>...
...
</optgroup>
<optgroup ...>
<option ..>...
<option ..>...
...

Answer 1

You can use Get List Items which will return a list of all items and then use Get Length to get the number of elements in the list:
Select Options Test
Open Browser your_url chrome
#{items} Get List Items id=select_list_id
${list_length} Get Length ${items}
Should Be True ${list_length} > 1

Answer 2

You have at least a couple of choices:
use the Get Matching Xpath Count keyword to return the number elements that match an xpath which represents the options, or
Use Get List Items to fetch all of the items, then use Get Length to return the length.
Since I can't write an example against your exact code, the following example runs against the page at http://the-internet.herokuapp.com/dropdown. It has markup that includes this (at the time I write this answer):
<select id='dropdown'>
<option value="" disabled="disabled" selected="selected">Please select an option</option>
<option value="1">Option 1</option>
<option value="2">Option 2</option>
</select>
Here is a complete working example:
*** Test Cases ***
| Example
| |
| | Go to | ${ROOT}/dropdown
| |
| | ${count}= | Get matching xpath count | //select[#id='dropdown']/option
| | Should be equal as numbers | ${count} | 3
| |
| | #{items}= | Get list items | //select[#id='dropdown']
| | ${item count}= | Get Length | ${items}
| | Should be equal as numbers | ${item count} | 3
