Won't this break if you have multiple selectable options?  Are you relying on
only ever having one?

[please use gerrit instead, 2016/05/03 21:38:33]

I am indeed relying on having only one in the integration test. When I write
more advanced tests, I will figure out how to click the first, second, or third
option. Are you OK with this approach?

Yeah, sounds good.
