Matching for text equality or containing text

[bertdemiranda]

According to the documentation of function Test.Html.Selector.text : String -> Selector

It "Matches elements that have a text attribute with the given value."
which suggests to me that a test for string equality would be performed.

Yet when I try the following test:

module HasTest exposing (..)

import Html
import Test.Html.Query as Query
import Test exposing (Test, test)
import Test.Html.Selector exposing (text)


hasTest : Test
hasTest =
    test "Button has the expected text" <|
        \() ->
            Html.button [] [ Html.text "????????I'm a button!????????" ]
                |> Query.fromHtml
                |> Query.has [ text "I'm a button!" ]

the test succeeds.

When I look at function Test.Html.Selector.Internal.query

(...)
Text text ->
    List.concatMap (fn (ElmHtml.Query.ContainsText text)) elems
(...)

then it calls indeed for a string containing match.

Also considering issue "Regex matching for text #58", should this behavior be corrected or should the documentation be changed/clarified?

Otherwise, how does one test for string equalitiy?
Is it possible to extract somehow the actual string from the query followed by a string equality check like so:

Html.button [] [ Html.text "????????I'm a button!????????" ]
    |> Query.fromHtml
    |> ...get string value(s)...
    |> Expect.equal "I'm a button!"

that should then fail.
