Visualization of Program Data
Abstract
This research will focus on providing visualzation techniques that
(1) will let developers view data about their programs and (2) expose
information that is not available or understandable through other
analysis techniques.
To date, we have developed a visualization system, Tarantula
that displays the results of running suites of tests against software
systems. By showing what portions of the code are executed by passed and
failed tests, the system helps developers identify faults in their programs.
Using our technique, the program under test is instrumented to output
statement coverage information for each execution, or test
case. Instrumentation adds probes to the original program that record
the execution (or non-execution) of each statement. A file is
created for each test case that lists the statements that are
executed by that test case.
This leads to a huge amount of data that is difficult to interpret
manually. To make this data comprehensible, we have created
Tarantula.
More information about Tarantula is available
here.
We are also creating a generalized visualization system that will
let users configure their own Tarantula-like system that displays
desired information.
