1. Navigation through Source Code
Prepared by
Soha Makady

2. Problem Statement
As the software changes, documents become obsolete, hence the source code becomes the only reliable documentation for the developer
But … as the software size increases, code navigation becomes a hard task
So… We need to provide a visual representation for the relationships between the source code elements

3. Data An XML-based representation for source code. Includes info about:
Packages
Classes (including attributes and operations)
Relationships
Inheritance: for classes and interfaces
Calls: records calls between different methods
References: for field references from a different class, or a method

4. Related Work
Locates a feature within the code

5. To Do (1) Visualize method calls to trace any feature Class1
attribute1
attribute2
method1()
method2()
method3()
Class2
Attribute3
Attribute4
method7()
method8()
method9()
m1() calls m9()
m3() calls m7() ….
m2() calls m9()

6. To Do (2) – May be 
Visualize the affected test cases by code modification
TestClass2
testMethod4()
testMethod5()
testMethod6()
Class1
attribute1
attribute2
method1()
method2()
method3()
TestClass1
testMethod1()
testMethod2()
testMethod3()
