This document describes the set of tests we need to build to have complete coverage
of incremental compilation for AspectJ. 

Please add additional test descriptions if you uncover basic scenarios that are missing.

 Types referred to in test specifications:
 ==========================================
 
 For the test descriptions that follow I assume a set of types with the following
 relationships:
 
 "Aspect" is an aspect
 "AbstractAspect" is the parent of "ConcreteAspect"
 "AspectDelegate" is a type called from within the body of the aspect
 
 "Class" is any class
 "SuperClass" is the parent of ....
 "SubClass"
 
 "ClassDelegate" is a type called from within Class, SuperClass, SubClass
 
 Simple Changes to Class
 =======================
 
 Class is advised by Aspect (both advice + ITD member(s)).
 
 INC-01 Change method signature in Class so that method that was previously unadvised now is. Structure model should
        update *all* markers for the Class with the new line numbers, and add new marker (both advised and advised-by)
        Expect 1xcompile, 1xincremental weave
        
 INC-02 As above, but change signature so that previously advised member is no longer advised.
 
 INC-03 Change a method that was advised, and remains advised after change - check line no's updated for relationships
   
 INC-04 Implement an additional interface in the Class, so that advice now matches
 
 INC-05 Add interface to Class, causing declare parents to match where it did not previously
 
 INC-06 As above but remove interface
 
 INC-07 Whitespace change in class with declare warning markers

 INC-08 Add interface X to Class, so that a declare parents now matches, adding additional interface Y.
        Another aspect in the system advises all calls to "foo" on instances of Y. Class has a foo method - 
        all types that call Class.foo should be rewoven. 
 
 Simple Changes to Aspect
 ========================
 
 Class is advised by Aspect.
 
 INC-11 Whitespace change in an aspect
 
 INC-12 Add method to an aspect
 
 INC-13 Change body of before advice
 
 INC-14 Change pointcut expression
 
 INC-15 Change body of around advice
 
 INC-16 Add new advice to aspect
 
 INC-17 Add new declare parents statement to aspect
 
 INC-18 Change declare parents statement
 
 Hierarchical Class Changes
 ==========================
 
 INC-20 Add interface to SuperClass such that operations in SubClass now become eligible for advising
 
 INC-21 Add method to SuperClass such that (now overridding) method in SubClass becomes eligible for advising
 
 INC-22 Add method to SuperClass with same signature as one ITD'd on an interface implemented by SubClass
 
 Hierarchical Aspect Changes
 ===========================
 
 INC-30 Change advice body in abstract aspect

 INC-31 Change comment in abstract aspect
 
 Delegate tests
 ===============
 
 INC-40 Change signature of operation in ClassDelegate, Class should be recompiled and re-woven
  
 INC-41 Change signature of operation in AspectDelegate, aspect should be recompiled and world re-woven  
  
 Cflow tests
 ============
 
 INC-50 A simple cflow is started by a join point in class Start and used in join point matching in Class. 
        Compile Class, Start, and Aspect. Change Start to remove the join point that starts the cflow.

 INC-51 As above, but make a white-space change in Aspect
 
 INC-52 As INC-50, but change Class
 
 INC-53 As 50, but cflow binds a context variable
 
 INC-54 As above, but make a white-space change in Aspect
 
 INC-55 As INC-53, but change Class
