Question

Is it possible to do some form of expect NEW in rhino mock.

Example:

public void ToBeTested()
{
     ClassForExmaple classForExample = new ClassForExample();

     //Other logic.....
}

So I want my unit test to call ToBeTested(), but when the new ClassForExample is called I want it to return a mocked version.

Answer 1

I have not worked with Rhino mock and I am not sure if this is something that is supported by RhinoMock but the fact that the control of creation of the object is embedded within the method violates the principles of DI/IOC and thus is harder to test.. Ideally the class should have been injected to the method either through the constructor of the containing class or to the method itself..

thus

class A
{
    IClassForExample _classForExample;
    public A(IClassForExample classForExample)
    {
      _classForExample=classForExample;
    }
    public void ToBeTested()
    {
         var classForExample = _classForExample;

         //Other logic.....
    }
}

Does RhinoSupport extending a non-abstract/interface class – a question I am not sure but I am sure it can mock the interface.
