    |The semantics of `RSpec::Core::Pending#pending` are changing in
    |RSpec 3.  In RSpec 2.x, it caused the example to be skipped. In
    |RSpec 3, the rest of the example will still be run but is expected
    |to fail, and will be marked as a failure (rather than as pending)
    |if the example passes.
    |
    |Any passed block will no longer be executed. This feature is being
    |removed since it was semantically inconsistent, and the behaviour it
    |offered is being made available with the other ways of marking an
    |example pending.
    |
    |To keep the same skip semantics, change `pending` to `skip`.
    |Otherwise, if you want the new RSpec 3 behavior, you can safely
    |ignore this warning and continue to upgrade to RSpec 3 without
    |addressing it.
