    Because TupleConverter cannot be covariant, we need to jump through this hoop.

    Because TupleConverter cannot be covariant, we need to jump through this hoop. A typical implementation might be: (implicit conv: TupleConverter[T]) and then:

    override def converter[U >: T] = TupleConverter.asSuperConverter[T, U](conv)

    The mock passed in to scalding.JobTest may be considered as a mock of the Tap or the Source.

    The mock passed in to scalding.JobTest may be considered as a mock of the Tap or the Source. By default, as of 0.9.0, it is considered as a Mock of the Source. If you set this to true, the mock in TestMode will be considered to be a mock of the Tap (which must be transformed) and not the Source.
