Rhino Mock을 이용한 직렬 프로그램 유닛 테스트

Mock은 이렇게 쓸 수 있구나.
1. 인터페이스 ISerialPort

    public interface ISerialPort

    {

        string PortName { get; }

        int BaudRate { get; }

        int DataBits { get; }

        Parity Party { get; }

        StopBits StopBits { get; }

        int BytesToRead { get; }

        bool IsOpen { get; }

        void Open();

        void Close();

        string ReadLine();

        int ReadByte();

        int Read(ref byte[] buffer, int offset, int count);

        string ReadTo(string p);

        void Write(byte[] data, int offset, int count);

    }

2.  Rhino Mock    

        [TestMethod()]

        public void ReadAlarmTest()

        {

            MockRepository mock = new MockRepository();

            ISerialPort serialPort = mock.StrictMock<ISerialPort>();

            VSerialPort target = new VSerialPort(serialPort);

            string excepted ="1,1,1,";

            string actual = string.Empty;

            StringBuilder sb = new StringBuilder();

            target.OnReceiveData += (alarmNo) =>{ sb.Append(alarmNo);sb.Append(',');};

            using (mock.Record())

            {

                byte[] data = GetAlarmData();

                byte[] outData = new byte[data.Length];

                serialPort.Expect(p => p.ReadByte()).Return(0x21);

                serialPort.Expect(p => p.Write(new byte[] {1,0x64,0x0D}, 0, 3));

                serialPort.Expect(p => p.BytesToRead).Return(data.Length);

                serialPort.Expect(p => p.Read(ref outData, 0, outData.Length)).OutRef(data).Return(data.Length);

                serialPort.Expect(p => p.BytesToRead).Return(0);

            }

            target.ReadAlarm();

            actual = sb.ToString();

            Assert.AreEqual(excepted, actual);

        }

        

        static byte[] GetAlarmData()

        {

            List<byte> data = new List<byte>();

            data.Add(1);

            data.AddRange(Encoding.ASCII.GetBytes("ALARM MON #01=001 \r
$\r
"));

            data.Add(1);

            data.AddRange(Encoding.ASCII.GetBytes("ALARM MON #01=001 \r
$\r
"));

            data.Add(1);

            data.AddRange(Encoding.ASCII.GetBytes("ALARM MON #01=001 \r
$\r
"));

            data.Add(1);

            data.AddRange(Encoding.ASCII.GetBytes("$\r"));

            data.Add(1);

            data.AddRange(Encoding.ASCII.GetBytes("000\r
"));

            return data.ToArray();

        }
