title: RhinoMocks - Not specifying all parameters in AssertWasCalled
body: <p>I am using RhinoMocks. Now I want to assert that some function was called, but I only care about one of the arguments. Can I do a <code>AssertWasCalled</code> where I only specify one argument? </p>
  
  <p>In the following example I'd like the ignore what was sent to the second argument of SomeOtherFunction(). I.e. I want to check that SomeOtherFunction was called with first parameter 123 and I don't care what the second parameter was. </p>
  
  <pre><code>[Test]
  public void SomeTest()
  {
      var myMock = MockRepository.GenerateMock&lt;ISomeInterface&gt;();    
      var myObj = new MyClass(myMock); 
      myObj.foo()
  
      myMock.AssertWasCalled(factory =&gt; factory.SomeOtherFunction(123, null));  
  }
  </code></pre>
