• fd10f13f chore!: remove assert.failException property (#2659) (Morgan Roderick)

  This was used for allowing customisation of the thrown error between sandboxes and for customisation for integrations (most likely from the days of BusterJS).

  To my knowledge and what I've been able to find on GitHub, this has never had any production use by end users.

  BREAKING CHANGE: this removes assert.failException from the API
