### Question:
SignalDescription { public String getUnit() { return unit; } protected  SignalDescription(MessageDescription description); protected  SignalDescription(MultiplexDescription multiplexDescription, MessageDescription description, long multiplexCount); void addLabel(Label l); Set<Label> getAllLabels(); MessageDescription getDescription(); long getMultiplexCount(); MessageDescription getMessageDescription(); MultiplexDescription getMultiplexDescription(); boolean isMultiplexed(); Object getParent(); Set<Node> getConsumers(); void addConsumer(Node consumer); ByteOrder getByteOrder(); void setByteOrder(ByteOrder byteOrder); int getLength(); void setLength(int length); String getName(); void setName(String name); int getOffset(); void setOffset(int offset); Type getType(); void setType(Type type); double getIntercept(); void setIntercept(double intercept); String getNotes(); void setNotes(String notes); double getSlope(); void setSlope(double slope); String getUnit(); void setUnit(String unit); Signal decodeData(byte[] data); static final Comparator<SignalDescription> nameComparator; }### Answer:
@Test public void testUnit() { System.out.println("Testing unit 1"); String expResult = "0.1 km/h"; String result = data.getUnit(); assertEquals(expResult, result); }
