            |The semantics of `RSpec::Core::Pending#pending` have changed in
            |RSpec 3. In RSpec 2.x, it caused the example to be skipped. In
            |RSpec 3, the rest of the example is still run but is expected to
            |fail, and will be marked as a failure (rather than as pending) if
            |the example passes.
            |
            |Passing a block within an example is now deprecated. Marking the
            |example as pending provides the same behavior in RSpec 3 which was
            |provided only by the block in RSpec 2.x.
            |
            |Move the code in the block provided to `pending` into the rest of
            |the example body.
