code: func InDeltaMapValuesf(t TestingT, expected interface{}, actual interface{}, delta float64, msg string, args ...interface{}) bool {
  	if h, ok := t.(tHelper); ok {
  		h.Helper()
  	}
  	return InDeltaMapValues(t, expected, actual, delta, append([]interface{}{msg}, args...)...)
  }
docs: // InDeltaMapValuesf is the same as InDelta, but it compares all values between two maps. Both maps must have exactly the same keys.
