  Specify or clear the number of repetitions for running until failure.

  Runs the tests repeatedly until failure or until the specified number of runs.
  If not provided, the count is cleared and the tests will run just once as
  usual.

  Corresponds to `mix test --repeat-until-failure <count>`.

  This option is only available in `mix test` in Elixir 1.17.0 and later.
