Description

The output of the axe.run command sometimes includes a failureSummary for a node in the nodes array. This field is not document anywhere however.

Thanks for the issue. We can probably add a note to the result array section of the api docs that documents that failureSummary is only for nodes in the violations array.

This field is not only present for nodes in the violations array, but also the incomplete array. See #1972.
