This should become 2 tests,

         "description": "2 is not a valid binary digit and so should raise an error",
         "binary":  "2",
         "expected" :  null,

and

         "description": "A number containing an invalid binary digit is invalid and should raise an error",
         "binary":  "01201",
         "expected":  null,

Discussion required: I'm not 100% sure null is the correct expected value here if we want to indicate in a general way that an error should be raised.

Binary should never be an array.
See my other comment above about splitting arrays into individual tests.

I'm not sure -1 is the right value to expect in the case of an error, it probably should be null.

I think -1 is fine as long as we note somewhere that it's a place-holder for an error. Each track can deal with it as they please.
