Parsing and conversion to CodeDOM 4

Accomplishments  Java and C# conversion into CodeDOM to support cross language detections are now equal (see green cells left)  Source code and statement line number associations now in place 5

White Box and Black Box Testing 20

 White Box Testing: ◦ Unit Testing  Black Box Testing: ◦ Production Rule Testing ◦ Stress Testing ◦ Functional Testing 21

 Console Project…bypasses GUI ◦ Parses source and builds CodeDOM ◦ No analysis ◦ Targets  JDK1.6  Microsoft Visual Studio

23

24

 Current Test Count: 33  Added test code to cover ◦ Clone analysis ◦ Some stress

28

 We are using our to track our bugs. 29

Where we currently stand 31

32  Below is the status of the tasks for this past iteration: ◦ Parsing/CodeDOM  C++ parsing – 15%  C# and Java are both equal for CodeDOM ◦ Clone Analysis  Tokenization & analysis – 75% ◦ GUI  Project management – 100%  Displaying source code – 100%  Sketches for visual design – 100% Where we stand….

33 ◦ Documentation – 96%  User Stories, Use Cases, UML Models, Sketches  Functional Tests  Update schedule ◦ Testing  Unit tests – 90%  Execute functional tests – 100%

 As of March 3, 2011  SLOC: ◦ CS666_Client = 5190 lines ◦ CS666_Core = 2988 lines ◦ CS666_Console = 287 lines ◦ CS666_CppParser = 484 lines ◦ CS666_CsParser = 3459 lines ◦ CS666_JavaParser = 3502 lines ◦ CS666_LanguageSupport = 84 lines ◦ CS666_UnitTests = 944 lines  Total = lines (including unit tests) 34 - Used lcounter.exe to count SLOC

Path Forward for the next iteration 37

38 Schedule

39  Below is a list of the tasks for our next iteration: ◦ Parsing/CodeDOM  C++ parsing  Java, C#, C++ conversion to CodeDOM ◦ Clone Analysis  Add property settings to clone analysis ◦ GUI  Project management  Clone analysis  Sketches for visual design Next Iteration

40 ◦ Documentation  User Stories, Use Cases, UML Models, Sketches  Functional Tests  Update schedule ◦ Testing  Unit tests  Execute functional tests  Record bugs/issues found Next Iteration
