Hi all,
How can we use "NUnit" in socket programming.
I mean, I'm writing a server program which accepts
connection requests from the clients. I want to test the
number of clients whenever a new connection is
established.
My Server code is :
---------------------------------------------------------------------
private string strHostName;
private IPAddress ipAddHost;
private Socket soketListener;
private int intPortNumber;
private int clients = 0;
public Server(int portNumber)
{
this.intPortNum ber = portNumber;
}
public void StartListening( )
{
strHostName = Dns.GetHostName ();
IPHostEntry ipHostInfo = Dns.Resolve(str HostName);
ipAddHost = ipHostInfo.Addr essList[0];
socketListener. Bind( new IPEndPoint( ipAddHost, intPortNumber ) );
socketListener. Listen( 100 );
socketListener. BeginAccept(
new AsyncCallback( this.OnConnecti onRequest ),socketListene r );
}
private void OnConnectionReq uest(Socket client)
{
clients ++;
}
public int GetClientCount( )
{
return clients;
}
-----------------------------------------------------------------------------
I have tried to use NUnit in the following way.
[SetUp]
public void init()
{
Server server = new Server(portNumb er);
}
[Test]
public void Test()
{
server.StartLis tening();
Socket clientSocket = new Socket(
AddressFamily.I nterNetwork, SocketType.Stre am,
ProtocolType.Tc p );
IPAddress localIp = IPAddress.Parse (ipAddress);
int portNumber = number;
IPEndPoint endPoint = new IPEndPoint(loca lIp,portNumber) ;
socketClient.Co nnect(endPoint) ;
Assert.AreEqual (1,server.GetCl ientCount());
}
but test is failing... at "Assert.AreEqua l(1,server.GetC lientCount());
the error message is expected <1> but was<0>
can any one suggest me how can we use NUnit in this situation.
Cheers,
Naveen Mukkelli. 5 4638
Have you try to accept the socket on the server object synchronously?

Hi,
As I am accepting connections asynchronously in my server application, hence
I would like to test asynchronous behaviour.
I have not tried accepting sockets, synchronously, on the serve object.
Can we test asynchronous connections at all ?
Cheers,
Naveen.

If you want to use NUnit, or unit testing in general, effectively, then you
really can't directly test your code as it makes calls into the socket
library. That's a valid test, but it's an integration test, not a unit test.
A good unit test is repeatable on any machine, including build machines;
this allows the unit tests to be run during the build process, and to halt
the build if a test fails. The build machines often do not have all the
tools and other infrastructure installed that the development or client
machines have on them, so tests that rely on a particular configuration are
more likely to fail. I like to keep the build machine as pure as possible to
avoid dependency contamination.
That being said, you can unit test your code, but you ought to create a mock
object that mimics the behavior of the socket library. There are various
open source tools, such as NMock, that make this easier. The purpose of the
mock object is to simulate the behavior of the external dependency,
including all possible errors that it can exhibit, so you can test your
code's reaction to those behaviors. The mock object will expose the same API
as the real object, and the code under test does not know which object it is
dealing with. The unit test code creates a mock object and substitutes it
for the "real" object before it runs the test.
There are books and white papers on this subject - I'd suggest googling up
some references and start reading. Once you get the hang of it it isn't
hard.

Hi,
Can we use NMock to simulate concrete classes?.
In my case, I have to a class with no interfaces and virtual methods.
I've got 2 classes A, B, dependent on each other. That means, one
Class A creates many objects of Class B.
For example..
public class DependenceClass
{
private string name = null;
public DependenceClass (string str)
{
this.name = str;
}
public DependenceClass ()
{
}
public void Wish()
{
Console.WriteLi ne("Hello " + this.name );
}
public string GetName()
{
return this.name;
}
public void SetName(string str)
{
this.name = str;
}
}
public class UnderTest
{
private DependenceClass dC = null;
public UnderTest(Depen denceClass dc)
{
this.dC = dc;
}
public string GetName()
{
return this.dC.GetName ();
}
public void SetName(string str)
{
this.dC.SetName (str);
}
}
my test class
[TestFixture]
public class TestClass
{
private DependenceClass dependenceClass = null;
[Test]
public void Test1()
{
IMock mock = new DynamicMock(
typeof(Dependen ceClass));
dependenceClass =
(DependenceClas s)mock.MockInst ance;
mock.ExpectAndR eturn("GetName" ,"Naveen",null) ;
Assert.AreEqual
("Naveen",depen denceClass.GetN ame());
}
The test is failing and the excpetion is : System.Argument Exception, Method
GetName is not Virtual.
How can we test class with no vitual methods and Interfaces.

I don't know what all the capabilities of NMock are - you should address
that question to the authors. Usually you use mock objects on interfaces and
base classes and you mock those methods - that would tend to imply the
methods must be virtual.
Quite often using mock objects requires you to rewrite/redesign your code to
make it easier to use. Typically you will define an interface or base class,
derive the real implementation from that, and define a mock object as well
for testing.
