Multiple test suites and the Java Platform
  - Currently we test By Value 
    
      - Incorporating tests is (relatively) simple, since we develop to (relatively) 
        common standards 
        
          - All Sun-developed test suites use the same test harness (JavaTest)
- Some differences nevertheless exist, particularly between J2SE and 
            J2EE test suites 
            
              - Different test metadata formats, build mechanisms
- Different execution environments
 
 
 
- Considering testing By Reference due to rapidly increasing size 
    of the platform test suites 
    
      - Need to improve the user-experience when multiple test suites are to 
        be executed
 
- We also incorporate W3C tests (eg, for XML Core, Schema) 
    
      - We'd really like to use By Reference for W3C specs 
        
          - Plug in any parser you want, so long as it passes version x.y of 
            the W3C parser test suite, located <here>
