**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));

I get that I can go my own way. Just hoping to help improve things. My first attempt at fixing it was to remove the query string from the test. What do you think about that. The problem I see is that it breaks compatibility.

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.
