Yes, that's true, CSS2 attribute selectors are as fast as class or ID based
ones, so there is no performance penalty to using them.
As a side note, since 0.13.0 Geb rewrites map based selectors into
attribute based selectors giving you the ability to use a friendlier syntax
without having to pay with performance for it. Therefore you can use the
following syntax:
$("form", "data-qa": "artist").value("1")
Also, note that I used the value() method to change value of a select
element and not an assignment as you all did in your examples. We are
dealing with a navigator here and we can't use the shorthand syntaxt as if
we were using a name to locate that element instead of an attribute.
