ExpectSet does not set properly when is calling itself

Hi,

Here's your test:

      [Test] 
      [VerifyMocks] 
      public void TestExpectSet2() 
      { 
         SizeDT size = SizeDT.Empty; 
         Mock mock = MockManager.Mock(typeof(SizeDT)); 
         mock.ExpectSet("X"); 
         size.ArgumentTest(); 
      } 

Notice that you call MockManager.Mock after you create "size" the instance you later call the function on.

Here's what happens: Mock means the next time you see a "new" it will be mocked. The next time a "new" is seen is inside ArgumentTest:

      public void ArgumentTest() 
      { 
         x = 10; 
         y =10; 
         SizeDT size = new SizeDT(x,y); 
         size.GreatStuff(100); 
         X = size.x; 
         X = -40; 
         Y = size.y; 
      } 

Note that this is a local "size". So this one is mocked, but the external "size" is not. Now, in the lines:

         X = size.x; 
         X = -40; 
         Y = size.y; 

The GET properties of the local (and mocked) "size" are called, and they are set into the external (and not mocked) "size". . However, since we didn't satisfy the expectation we set on the external "size", but on the local "size", and we didn't set anything on the local size.x, you get the verification exception.

So what you need to do is call Set on the instance you plan to mock.

Let me know if I can help further.

I see, thanks for your explanation..

Hi,
I am curious about how does the

ExpectSet("X", noOfRuns)

work.

Continuing on the previous example, I modified my test to the following

      [Test]
      [VerifyMocks]
      public void TestExpectSet2()
      {
                        int noOfRuns = 1;
         Mock mock = MockManager.Mock(typeof(SizeDT));
         mock.ExpectSet("X", noOfRuns);
         SizeDT size = SizeDT.Empty;
         size.ArgumentTest();

and the test passes. Good.

So I change the noOfRuns from 1 to 2, and it still passes.

If I change the noOfRuns to 3, then the test fails because

TestCase 'ClassLibrary1.Class1.TestExpectSet2'
failed: TypeMock.VerifyException :
TypeMock Verification: Method ClassLibrary1.SizeDT.set_X() has 1 more expected calls

As far as I know, the noOfRun specifies how many times you expect a property to be set. If you expect it to be set 1 times, then you can't expect it to be set 2 times, and the converse is true, isn't it? How can you have a property to be set 1 and 2 times at the same time?

Oops, I forgot to write down the modified ArgumentTest() function. This is the modified ArgumentTest() function:

      public void ArgumentTest()
      {
         x = 10;
         y =10;
         SizeDT size = new SizeDT(x,y);
         size.GreatStuff(100);
         X = size.x;
         X = -40;
         Y = size.y;
      }

Sorry for the confusion, I think I get the issue resolved.

Hi,

What is always helpful, is using the Trace tool - found under the Program Files->TypeMock.Net->Tracer. It can show you all expectations, on which instances, mocked and unexpected calls.

gilz, thanks for the information. :o
