**on** equals vs. contains compromise?

gistfile1.fs

let on (u: string) =
    try
        wait pageTimeout (fun _ -> browser.Url = u)
    with
        | ex -> if browser.Url.Contains(u) = false then raise (CanopyOnException(sprintf "on check failed, expected expression '%s' got %s" u browser.Url));

Can you give an example. Not sure what would break compatibility.

How about this:

url "http://localhost/path/action?id=1234"
on  "http://localhost/path/action?id=1234" //should succeed
on  "http://localhost/path/action" //should succeed
on  "http://localhost/path/action/subaction" //should fail (currently succeeds)

let on expected = 
  let url = _browser.Url
  if url = expected then true else whackQuerystring(url) = expected

I am suggesting that if the url does not match that on would whack the query string and compare again.

I see, your suggestion seems totally reasonable

Cool I'll get you a PR when I get a chance sadly my laptop charger is busted so that means Monday.
