locating elements: testing library calls this "queries" and it works like capy and others: you have a bunch of methods that locate elements and wait a while for them to show up.
you often want one of these:
• I expect exactly one of X
• I expect exactly N of X
• I expect at least N of X
• all of the above but where “X" meets some criteria you cannot specify in a selector
and you often know if X should be on the page or not.
I don't think any e2e library implements this 2/?
