You didn't look at my example very careful.

I give it in simplified form:

Procedure TTestSomething.MyTest;

begin
   If (MyObject.MyProperty<>'') then
     Fail('MyProperty must be empty');
end;

For a string, you would probably use AssertEquals, but there are lots of 
cases where you cannot use AssertEquals, as there is nothing to be equal to.

The above kind of construct tests all it needs to test, yet does not call AssertEquals.

Since no AssertEquals is called, it will give a false warning in your test framework.
